Power for the digital revolution.  
 
Introduction  
Thank you for choosing Harman Kardon.  
The CDR 20 CD Player/Recorder is a unique  
product, designed not only to play back your  
existing library of compact discs, but also to  
record compact discs from either analog or digi-  
tal programs. You may feed signals (for record-  
ing) to the CDR 20 from external sources such  
as an A/V receiver, a tuner, a tape deck or a CD  
player, or you may simply place a CD in one  
deck, and make a copy using a recordable CD  
in the other deck.  
Special Features  
Important Information About CD  
Recording  
Dual-Deck CD Player and CD-R/CD-RW  
Recorder  
In order to get the most enjoyment from your  
new CD-R recorder, please pay special attention  
to the following sections of the manual that  
provide information about the special features  
and capabilities of CD Recorders.  
X4 Dub Speed for Both CD-R and  
Erasable CD-RW Discs  
Audiophile-Grade Digital-to-Analog  
Converters for Highest Audio Quality  
The CDR 20 plays all standard CD audio  
discs but for recording, the CDR 20 uses  
special CD-R and CD-RW discs designed  
only for audio use. CD-R discs designed for  
computer use will not work in the CDR 20.  
See page 14 for more information on which  
types of discs are used with the CDR 20.  
Dual-Play Capability  
Extensive Playback Programming  
Capabilities  
Designed and engineered by Harman Kardon,  
the CDR 20 is among the first audio CD  
recorders with x4 speed capability. This means  
that it will take only 15 minutes to copy a  
60-minute disc.  
Coaxial and Optical Digital Inputs and  
Outputs  
The last step in making a CD-R recording is  
the finalization process. Unless this step is  
properly done, the disc will not work in other  
players. See page 22 for information on  
finalizing discs.  
Front-Panel Coaxial Digital Input for  
Use with Portable Devices  
The CDR 20 not only records with the highest  
speed and quality available but it is also an  
audiophile CD player. Through the use of  
Sample-Rate Converter Allows Use of  
DAT Players as Digital Source  
Ergonomic Remote Control  
Once finalized, CD-R discs will play in any  
CD player, but CD-RW discs will only play in  
the CDR 20 and certain other machines.  
Check the specifications of your CD player if  
you have questions about compatibility with  
CD-RW discs.  
audiophile-grade digital-to-analog converters  
(DACs), the CDR 20s performance rivals the  
most sophisticated high-end players. Should  
you wish to bypass the internal DACs and use  
an external digital processor, coax and optical  
digital outputs are available. Thanks to the CDR  
20s dual-tray design, you may even play back  
two separate discs at the same time, for parties  
or multi-room applications. To make CD play-  
back more enjoyable, the CDR 20 also features  
a wide range of program and repeat functions.  
As with all CD players, except those  
designed specifically for portable use, you  
should never move a CD player while there  
is a disc inside one of the decks. NEVER  
move the CDR 20 until discs have been  
removed from both decks.  
Since CD recorders are a relatively new technol-  
ogy, this may be your first CD-R product.  
Although CD recorders resemble play-only CD  
machines in many ways, there are some impor-  
tant differences between a standard CD and a  
CD-R. In addition, making a CD-R recording is  
also a different process than what you may be  
familiar with for making audio tape or cassette  
recordings. For that reason, we encourage you  
to read through this manual so that you are  
fully acquainted with the way CD recording  
works. This small investment in your time will  
pay major dividends in the enjoyment that will  
result from proper use of the CDR 20.

antee that harmful interference will not occur in  
a particular installation. If this equipment does  
cause harmful interference to radio or television  
reception, which can be determined by turning  
the equipment off and on, the user is encour-  
aged to try to correct the interference by one or  
more of the following measures:  
Important Safety Information  
Verify Line Voltage Before Use  
Your CDR 20 has been designed for use with  
100- to 240-volt AC current. Connection to a  
line voltage other than that for which it is  
intended can create a safety and fire hazard  
and may damage the unit.  
Make certain that proper space is provided  
both above and below the unit for ventila-  
tion. If this product will be installed in a  
cabinet or other enclosed area, make certain  
that there is sufficient air movement within  
the cabinet.  
Reorient or relocate the receiving antenna.  
If you have any questions about the voltage  
requirements for your specific model, or about  
the line voltage in your area, contact your sell-  
ing dealer before plugging the unit into a wall  
outlet.  
Increase the separation between the equip-  
ment and receiver.  
Do not place the unit directly on a carpeted  
surface.  
Connect the equipment into an outlet on a  
circuit different from that to which the  
receiver is connected.  
Avoid installation in extremely hot or cold  
locations, or an area that is exposed to direct  
sunlight or heating equipment.  
Do Not Use Extension Cords  
Consult the dealer or an experienced  
Avoid moist or humid locations.  
We do not recommend that extension cords be  
used with this product. As with all electrical  
devices, do not run power cords under rugs or  
carpets or place heavy objects on them.  
Damaged power cords should be replaced  
immediately by an authorized service depot  
with cords meeting factory specifications.  
radio/TV technician for help.  
Do not obstruct the ventilation slots on the  
top of the unit, or place objects directly over  
them.  
This device complies with Part 15 of the FCC  
Rules. Operation is subject to the following two  
conditions: (1) this device may not cause harm-  
ful interference, and (2) this device must accept  
interference received, including interference that  
may cause undesired operation.

When the unit gets dirty, wipe it with a clean,  
soft dry cloth. If necessary, wipe it with a soft  
cloth dampened with mild soapy water, then a  
fresh cloth with clean water. Wipe dry immedi-  
ately with a dry cloth. NEVER use benzene,  
aerosol cleaners, thinner, alcohol or any other  
volatile cleaning agent. Do not use abrasive  
cleaners, as they may damage the finish of  
metal parts. Avoid spraying insecticide near  
the unit.  
Handle the AC Power Cord Gently  
When disconnecting the power cord from an  
AC outlet, always pull the plug, never pull the  
cord. If you do not intend to use the unit for  
any considerable length of time, disconnect the  
plug from the AC outlet.  
NOTE: Changes or modifications may cause  
this unit to fail to comply with Part 15 of the  
FCC Rules and may void the users authority to  
operate the equipment.  
Unpacking  
The carton and shipping materials used to pro-  
tect your new receiver during shipment were  
specially designed to cushion it from shock and  
vibration. We suggest that you save the carton  
and packing materials for use in shipping if you  
move, or should the unit ever need repair.  
Do Not Open the Cabinet  
There are no user-serviceable components  
inside this product. Opening the cabinet may  
present a shock hazard, and any modification  
to the product will void your guarantee. If water  
or any metal object such as a paper clip, wire  
or a staple accidentally falls inside the unit, dis-  
connect it from the AC power source immedi-  
ately, and consult an authorized service station.

Before moving the unit, be certain to discon-  
nect any interconnection cords with other com-  
ponents, and make certain that you disconnect  
the unit from the AC outlet.  
To minimize the size of the carton in storage,  
you may wish to flatten it. This is done by care-  
fully slitting the tape seams on the bottom and  
collapsing the carton down to a more two-  
dimensional appearance. Other cardboard  
inserts may be stored in the same manner.  
Packing materials that cannot be collapsed  
should be saved along with the carton in a  
plastic bag.  
IMPORTANT NOTE: To avoid damage to the  
CDR 20 which may not be covered by the war-  
ranty, be certain that all discs are removed from  
the unit before it is moved. Once the CDR 20 is  
installed, discs may be left in the unit when it is  
turned off, but the unit should NEVER be  
moved with discs left in either deck.  
CAUTION: The CDR 20 uses a laser system. To  
prevent direct exposure to the laser beam, do  
not open the cabinet enclosure or defeat any of  
the safety mechanisms provided for your pro-  
tection. DO NOT STARE INTO THE LASER BEAM.  
To ensure proper use of this product, please  
read this owners manual carefully and retain it  
for future use. Should the unit require mainte-  
nance or repair, please contact your local  
Harman Kardon service station. Refer servicing  
to qualified personnel only.

11 REMOTE CONTROL FUNCTIONS  
 
Installation and Connections  
Important Note: To prevent possible damage  
to your speakers or other components in your  
audio system, we strongly recommend that ALL  
system components, including the CDR 20, be  
turned off and unplugged from their AC power  
source when any connections are made or a  
new component is installed.  
Play-Deck Connections  
To make recordings from external digital  
sources, such as a CD, DVD or MD player, con-  
nect the CDR Coax-In jacks §6 or CDR  
Optical In Jack on the CDR to the digital  
output jacks on your receiver or processor. If  
your receiver does not have digital-output jacks,  
you may connect the CDR Coax In jacks  
§6 or CDR Optical In Jack on the CDR  
20 directly to the digital outputs on your CD  
player or other digital device.  
The rear-panel connections labeled “CDP” refer  
to the outputs of the Play Deck 3, which  
functions as a standard CD player. Connect the  
analog left/right CDP outputs ¡ to the CD  
inputs on your receiver, preamp or surround  
processor. For best playback results, a digital  
connection is recommended, using the coaxial  
or optical ¢• outputs. Connect them to the  
matching digital inputs of your receiver, pre-  
amp, processor or external digital decoder. Note  
that you may have to change a setting on the  
receiver or processor to link the digital input to  
the “CD” button or input selector. Consult the  
owners manual on that device for details, as  
this configuration may vary from unit to unit.  
Locating the CDR 20  
Since the CD transports in the CDR 20 are pre-  
cision instruments, they are subject to interfer-  
ence from vibration. To minimize the possibility  
of skipping during playback or recording, it is  
recommended that the unit be placed on a  
level, solid, vibration-free surface.  
Connections to a portable digital CD or MD  
player may also be made by connecting the  
Coax Digital Output of the player to the Front-  
Panel Digital Input 6 on the CDR 20.  
Note that when both the front and rear panel  
digital inputs are connected to external sources,  
the CDR 20 will give priority to the front-panel  
input 6. If it is impractical to disconnect the  
front-panel input when you need to use the  
rear-panel jack, simply turn off the device con-  
nected to the front-panel input. This will stop  
the digital signal, and permit the rear-panel  
jack to be used.  
When installing the CDR 20 in a cabinet or  
tight space, always make certain that there is  
enough room in front of the unit for the disc  
drawers to open fully, and that there is enough  
space above the unit so that discs may easily  
be inserted in the disc drawers.  
Record-Deck Connections  
The rear-panel connections labeled “CDR” refer  
to the inputs and outputs for the Record Deck  
%. Depending on the capabilities of your  
receiver, preamp or processor, you may find it  
convenient to connect the analog inputs and  
outputs to the jacks marked for a tape recorder.  
As the CDR 20s functions resemble those of  
a standard tape recorder, this might make it  
easier to select it as an input on your receiver  
or preamp. Connect the analog CDR-Out jacks  
to the Play/In jacks of a Tape or Aux input  
on your receiver or preamp. Connect the CDR-In  
jacks £ to the Tape Rec/Out jacks on your  
receiver or preamp.  
In addition to the safety considerations outlined  
on page 4, it is also recommended that the  
CDR 20 not be placed in a location that is sub-  
ject to direct sunlight or extreme heat or cold,  
as these conditions may damage the discs used  
in the player, or the player itself. Note that  
audio amplifiers or high-power receivers, as  
well as certain other electronic products, may  
generate significant heat. For that reason, do  
not place the CDR 20 directly on top of an  
amplifier, receiver, or other heat source. Always  
allow at least one inch of free space on all  
sides of the CDR 20, as well as other electronic  
products, to allow for proper ventilation.  
IMPORTANT NOTES ON DIGITAL  
CONNECTIONS:  
Although digital-coax connections use the same  
type of “RCAphono jack as standard analog  
signals, please take special care to connect digi-  
tal signals only to digital jacks. In many cases,  
the digital jacks may be identified by an  
orange-colored insert ring around the center of  
the jack. When making digital connections, be  
sure to use coax-interconnect cables, such as  
the one supplied with the CDR 20 or cables  
intended for video applications. Even though  
they have the correct type of RCA connector, do  
not use audio-interconnect cables that have  
twisted-pair construction, as they are not  
appropriate for digital signal use. If you have  
any questions about the type of cables to use  
with the CDR 20, consult your dealer.  
To play the output of the Record Deck through  
the digital decoder in your receiver or an exter-  
nal processor, connect the CDR Coax-Out ∞  
jacks to the matching digital-input jacks on  
your receiver or processor. Note that you may  
have to change a setting on the receiver or  
processor to link the digital input to the “Tape”  
button or the specific input selector associated  
with the digital inputs. Consult the owners  
manual on your receiver or processor for  
details, as this configuration may vary from unit  
to unit.  
The unit should also be kept away from sources  
of water or damp conditions.  
Connections to Your Audio System  
When connecting the CDR 20, think of the  
process as if your were connecting a standard  
CD player and a tape or cassette recorder, with  
the addition of the digital connections.  
12 INSTALLATION AND CONNECTIONS  
 
Installation and Connections  
Batteries  
IR Remote Connections  
Insert the two AA batteries supplied with the  
CDR 20s remote by turning the remote over so  
that the bottom of the remote is facing towards  
you. Gently lift the plastic tab on the battery  
cover up and away from you, and lift the lid off.  
Insert the batteries in the remote, being careful  
to follow the + and – polarity indications in the  
bottom of the compartment. Replace the cover  
by first seating the two small tabs into the mat-  
ing holes at the top of the remote, and then  
gently push the cover down until the latch  
snaps into place with an audible click.  
If the CDR 20 is installed behind a cabinet or  
other obstruction that may block the path  
between the front-panel Remote Sensor Û  
and the location where you will use the remote,  
an optional external IR sensor may be used.  
Connect the sensor to the Remote IR In Jack  
ª on the rear-panel. This jack may also be  
connected to the IR Output jack of another  
compatible Harman Kardon component or a  
compatible IR system remote product.  
You may also use the IR Sensor in the CDR 20  
to send commands to other compatible remote  
products. Connect the Remote IR Out Jack  
to the input of the other product or system.  
Power Connections  
Connect the AC Power Cord to an AC  
power source. the CDR 20 uses sensitive, high-  
performance computer-grade CD drives, and to  
protect them we recommend that you consider  
the use of a surge protector, just as you would  
for a computer.  
If the rear-panel AC outlet on a receiver or  
other product is used, make certain that it  
provides at least 28 watts, and that the total  
power of all products connected does not  
exceed the maximum rated output of the prod-  
uct containing the outlets. If the CDR 20 is con-  
nected to a switched outlet, remember to turn  
on the outlet or product controlling it in order  
for the CDR 20 to operate.  
NOTE: When replacing batteries, it always a  
good idea to replace both at the same time.  
When the remote will not be used for an  
extended period of time, it is also a good idea  
to remove the batteries to avoid the possibility  
of damage due to corrosion. Batteries contain  
chemical substances and we recommend that  
you dispose of them properly and in compliance  
with any local regulations.  
13 INSTALLATION AND CONNECTIONS  
 
CD Recording Basics  
CD Recorders (CDRs) are similar to standard CD  
players, with the addition of the features and  
controls needed for recording. Functions such  
as play, search and programming for playback  
will be familiar, but the recorder will function  
slightly differently than what you may be used  
to for magnetic tape recorders.  
TOC: Stands for Table of Contents and it  
refers to the data recorded on each CD that  
tells the player how many tracks are on the  
disc, the total time of the disc and the running  
time of each individual track. Each time a disc  
of any sort is placed in the CDR 20, you will see  
a TOCto indicate that the unit is reading this  
data from the disc. This is required to copy the  
track information to any recording.  
R e c o r d a b le  
Re W r it a ble  
Discs designed for use in  
computer CD-R drives may not be used for  
recording in the CDR 20. Only discs specifically  
designed for use in consumer CD audio  
recorders may be used. If you attempt to  
use a blank-computer-type recordable disc for  
recording on the CDR 20 you will see a  
NOAUDIOmessage in the Information  
Display K and recording will not be possible.  
However, discs that have been recorded in the  
CD-R drive of a computer may be played in the  
CDR 20, provided that they have been properly  
finalized in accordance with audio standard  
IEC958.  
Disc Types  
Unlike a conventional CD player, the CDR 20  
uses three types of discs, and it is important to  
understand how each one plays.  
OPC: Stands for Optical Processing  
Calibration. When you see this message in the  
Information Display for the Record Deck  
K, it means that the laser transport inside the  
unit is making the calibrations and adjustments  
needed so that the recording process is  
optimized for the specific disc in use.  
Both decks in the CDR 20 will play  
back any conventional CD that bears this logo.  
Note that the CDR 20 is specifically designed  
for the recording and playback of consumer  
audio discs, and cannot be used to copy data  
discs, DVD discs, or other optical discs used by  
video- or computer-game systems.  
BUSY: When you see this message, it means  
that the Record Deck is completing part of the  
record operation. When you see this message,  
do not press any buttons; simply wait until the  
message clears from the display.  
R e c o r d a b le  
Discs that bear this logo may be  
recorded on one time, and when they are final-  
ized they will play in either deck in the CDR 20  
or in any conventional CD player, including  
home, car and portable models. The Record  
Deck % on the CDR 20 may also be used  
to record on these discs, and it will play  
CD-R/Audio discs even if they have not been  
finalized.  
CDR Terminology and Display Messages  
Compact disc recording has its own special  
terminology, and some of the messages  
displayed by the CDR 20 may be new to you.  
Before using the CDR 20, you may wish to  
familiarize yourself with some of the terms used  
by the CDR 20. Additional error message dis-  
plays may also appear. Please see page 23 for a  
complete explanation of error messages.  
DISC FULL: When there are only four  
seconds of record time remaining on a blank  
disc, a DISC FULLmessage will appear  
in the Information Display ˚. When you  
see this message, you will need to stop the  
recording process and, when a CD-R is being  
recorded, insert a new blank disc or, when a  
CD-RW is in use, either use a new disc or erase  
existing tracks following the instructions on  
page 22.  
Re W r it a ble  
Discs that bear this logo may be used  
Finalize: This term refers to the process  
that completes the recording of a disc by  
recording a final Table of Contents and prepar-  
ing the disc so that it may be played on other  
machines. A CD-R disc may not be played on  
other CD players until it is finalized. However,  
once the finalization process is complete, a  
CD-R disc may not be recorded on again. Only  
CD-RW discs may be “Unfinalized,” so that  
additional tracks may be recorded on a disc.  
for recording on the CDR 20, and they may also  
be erased and reused. They may be recorded on  
or played on the Record Deck % of the  
CDR 20 and in other CD-RW recorders or  
CD-RW compatible players. They will NOT play  
back in most current CD players unless the  
player is CD-RW compatible. CD-RW Audio  
discs will play on most DVD players once they  
have been finalized.  
14 CD RECORDING BASICS  
 
Playback Basics  
Playback of CDs on the CDR 20 resembles that  
for traditional CD players with a few exceptions  
to accommodate the availability of two sepa-  
rate playback decks. Before using the CDR 20,  
power-up the unit by pressing in the Main  
Power Switch 1. Note that the Status-  
Mode Indicator 2 will turn green, indicating  
that the unit is on and functioning. At the same  
time, the Information Display Ú will illuminate  
and the legends behind the front-panel controls  
will also light up.  
Load a disc in the tray with the printed (label)  
side facing up. Once the disc is seated, make  
certain that it is properly centered within the  
tray. When using 3" discs, take extra care to  
make certain that the disc is carefully centered  
within the smaller ridges in the disc tray.  
Using the Remote  
The CDR 20s infrared remote control is  
designed to operate both CD decks, as well as  
control the playback programming and record  
functions. To allow for efficient use of the  
remote, its operation is different from standard  
CD players. Some buttons are dedicated to one  
specific CD deck, while others are shared  
between the two decks.  
No matter which deck is playing, the Play  
Deck (CDP) and Record Deck (CDR)

Status-Mode Indicator 2 goes out, the  
CDR 20 is off and not drawing any power.  
When you will not be using the unit for an  
extended period of time, such as during a  
vacation, we recommend using the Main  
Power Switch 1 to turn the unit  
3 or the CDR button  
Record Deck %. When the button is pressed,  
a message reading CDP or CDR will appear in  
the appropriate Information Display K to  
confirm the selection.  
If the disc is a standard CD or a finalized CD-R  
or CD-RW disc, TOCwill flash while the unit  
reads the discs Table of Contents information.  
Once that data is read, the Information  
Display K will show the total number of  
tracks and the total time of all tracks on the  
disc. The CD Indicator S will also light to  
indicate that a standard CD is in use.

for the deck you wish to con-  
completely off.  
Note that features relating to the recording  
process, such as Speed s and the double  
row of record-function buttons in the center of  
the remote lmnotuvw  
and the Single/Dual buttons g` are  
dedicated feature buttons that do not require  
any special selection.  
Although compact discs are very reliable, rough  
handling may damage them. Avoid scratching  
the bottom (nonprinted) side of the discs, as  
this will affect playback of standard CDs and  
interfere with the recording of CD-R and  
CD-RW discs. It is also a good idea to always  
handle discs by their edges to avoid fingerprints  
which may also interfere with playback quality  
and possibly cause damage to the laser and  
lens assembly.  
When an unfinalized CD-R or CD-RW disc is  
placed in the Record Deck %, the letters  
OPCwill flash once the Table of Contents has  
been read. This indicates that the unit is opti-  
mizing its circuits for maximum compatibility  
with the specific recordable disc in use. The  
number and total running time of any tracks  
that have already been recorded will appear in  
the Information Display K, and the appro-  
priate indicator SP will light to tell you if a  
CD-R or CD-RW disc is in use.

15 PLAYBACK BASICS  
 
Playback Basics  
Normal Play  
To momentarily stop the disc at any time, press  
the Pause button y(¯. When a disc is  
paused, the Play/Pause Indicator Q will add  
two vertical lines to indicate a paused disc.  
Press either the Play button j*˘ or the  
Pause button y(¯ to resume playback  
at the point where the disc was paused.  
Search  
To play a disc, first make certain that the unit is  
properly installed and that the Main Power  
Switch 1 is turned on. Turn the CDR 20 on  
by pressing the Power-On button a on the  
remote and note that the front-panel display  
will illuminate.  
You may quickly scan through the contents of a  
disc while listening to the playback at high  
speed in forward or reverse. To move forward  
through a disc, press the Forward Search but-  
28  
ton  
on the remote or press and hold the  
Next button Óˆ on the front panel that is  
appropriate for the deck in use. To move back-  
wards through a disc, press the Reverse  
Search button f on the remote, or press  
and hold the Previous button Ô˜ on the  
front panel that is appropriate for the deck in  
use. When using the remote, always remember  
to make certain that you have selected the deck  
you wish to control by pressing the appropriate  
selector button d 29 before entering the  
desired remote command.  
Insert a disc following the instructions shown  
on the previous page. To start the playback,  
press the Play button on the front panel for the  
appropriate deck or press the Select but-  
ton on the remote for the desired deck d  
29 and then press the Play button on the  
remote j. The Play/Pause Indicator Q  
will show a right pointing triangle and the  
Information Display K will show the track  
number being played and the running time of  
the track. As each new track begins to play, the  
track time will reset to 00:00and begin to  
count up for the new track.  
When there is only one disc in the unit, it will  
automatically stop when all tracks on a disc  
have played through. To stop playback at any  
time, press the Stop button x&¸ for the  
deck in use.  
When there is a disc in each deck, the player  
will respond in one of two ways, depending on  
which way the dual-play setting is activated. In  
normal operation, when the disc in one drawer  
finishes, the disc in the other drawer will begin  
to play. When the Dual button is  
pressed so that the Dual-Play Indicator J is  
lit, each deck will operate as a separate, single-  
play CD unit without regard to the status of the  
other deck. For complete information on Dual-  
Deck and Dual-Play operation, see page 17.  
Track Skip  
To move from one track on a disc directly to  
another, enter the number for the desired track  
with the Numeric Keys p. The disc will  
pause briefly to locate the track, and then  
immediately play it. When entering a two digit  
track number, the second digit must be entered  
within three seconds of the first digit.  
NOTE: Remember that Unfinalized CD-R or  
CD-RW discs will only play in the Record  
Deck %. If you attempt to play an Unfinalized  
disc in the Play Deck 3, a DISC  
ERRORmessage will appear to remind you  
to play the disc in the other deck.  
At the end of a listening session, remove the  
discs from the decks by following the instruc-  
tions shown on the previous page. Do not leave  
the disc drawers open when the unit is not

be fed to all digital and analog jacks for both  
decks. This means you may select the input on  
your receiver, preamp or processor for either  
deck. For example, if you have the Play Deck  
connected to “CD” and the Record Deck con-  
nected to “Tape,” when only one deck is play-  
ing, either input may be selected.  
Since the CDR 20 has two separate CD decks, it  
may be used as a two-disc changer, so that you  
can continually play two discs.  
press the Display Button b  
the deck in use so that the Total Time  
Indicators NL illuminate. The Information  
Display K will show the total time remaining  
for all tracks on the disc and count down until  
the disc has finished playing. When the disc has  
played all the way through, the total number of  
tracks and the total running time of the disc  
will be displayed.  
When the CDR 20 is in the Single-Play mode,  
as shown by the Dual-Play Indicator J  
NOT being lit, when the disc in one deck has  
played through to the end, the disc in the other  
deck will automatically begin to play. Each disc  
will play through, and when one deck is fin-  
ished the other will start. To stop playback,  
press the Stop button x&¸ for the deck  
that is currently playing.  
Headphone Listening  
You may listen to the output of the CDR 20  
through headphones at any time by simply  
plugging the headphones into the Front-Panel  
Jack 4. The volume of the headphone output  
may be adjusted with the Headphones Level  
Control 5. Note that changes to the head-  
phone level will not alter the output settings to  
the analog outputs. Those levels are fixed, and  
the volume should be adjusted using your  
receiver, preamp or processor.  
It is also possible to play two discs at once,  
using the Dual mode. To initiate dual-mode  
playback, press the Dual button on the front  
panel or remote ı`. When the Dual-Play  
Indicator J is lit, you may play a different  
disc in both decks at the same time. The output  
of each deck will be sent to the appropriate  
output jacks, and you will need to select the  
deck you wish to listen to using the input selec-  
tors on your receiver, preamp or processor. You  
may also use the output of one deck to feed  
your main-room system, while the second deck  
is used to feed a remote room.  
To have the CDR 20 function as two separate  
CD players, where the deck in use stops at the  
end of a disc, press the Dual button `ı  
until the Dual-Play Indicator J lights. In the  
Dual mode, each deck acts independently of the  
other and when the disc in one deck finishes, it  
stops unless one of the Repeat functions has  
been activated.  
Note that when only one deck is playing back a  
disc in the Single-Play mode, the output of that  
deck will be fed to the headphone jack. When  
the unit is in the Dual-Playback mode, only the  
output of the Play Deck 3 will be fed to the  
headphone jack.  
Time Display  
The CDR 20s time display is capable of show-  
ing a wide range of information about the con-  
tents of a CD.  
As long as the Dual-Play Indicator J is lit,  
each deck functions as a separate CD player,

19 PROGRAM PLAY  
 
CD Recording  
Making recordings on the CDR 20 is simple and  
easy once you become accustomed to the  
basics of CD Recording. Before making your  
first recording, please take a moment to review  
the CDR Basics on page 14. In particular, you  
will need to become familiar with the types of  
discs that may or may not be used in the  
CDR 20. In addition, some terms used in the  
following pages may be new to you. The follow-  
ing definitions and information will help you to  
make CD recordings using the CDR 20s many  
features:  
Next, select a dub speed. The default speed is a  
real-time dub, where the recording takes as  
long as the actual running time of the disc.  
However, with the CDR 20 you may also select  
x2 dubbing or x4 dubbing. Press the Speed  
button s# to select a speed as indicated by  
the x2/x4 Indicators F. When no Speed  
Indicator lights, the unit is set to real-time  
recording. Note that the slower the record-dub  
speed, the more tolerant the unit is of errors on  
the blank disc. However, with most high-quality  
blank discs, the 2x and 4x speeds should not  
present a problem.  
Some commercial CD discs may contain a  
copy protection data bit that will prevent a  
digital copy of the disc to be dubbed. In that  
case, the Copy Prohibit Indicator G will  
light to remind you that the inability to record  
is intentional, and not the result of a problem  
with the CDR 20.  
This product is equipped with the Serial Copy  
Management System (SCMS) to protect the  
rights of copyright owners. Although it is  
possible to make a copy of most CDs for  
your own personal use, it is not possible to  
make a digital copy from another digital copy  
but it is possible to make an analog copy of  
a digital copy.  
The CDR 20 accepts analog inputs and digital  
coax or optical inputs. Before making a  
recording, be certain that you have selected  
the correct input.  
Before beginning a dub, make certain that there  
is sufficient blank space on the record disc. To  
do this, first determine the time available on  
the blank disc by subtracting the time of previ-  
ously recorded material, if any, that is shown in  
the record side Information Display K, from  
the total time available on the disc. That num-  
ber should be greater than the total time of the  
disc to be dubbed, which is shown in the play  
side Information Display K.  
RECORDINGS MAY BE MADE FOR  
PERSONAL USE ONLY, AND ANY  
UNAUTHORIZED COPYING IS SUBJECT  
TO THE APPLICABLE LAW.  
After a disc is recorded, it must be finalized.  
This process adds a table of contents data to  
the disc and makes it playable on other  
machines. Until a disc is properly finalized, it  
may not be played on standard CD players.  
The CDR 20 may record on either CD-R or  
CD-RW discs, but they must be of the type  
specifically designed for use in consumer-  
audio CD recorders. These discs may be rec-  
ognized by looking for the words “Digital  
Audio” in the compact disc logo on the blank  
disc or its packaging. Discs with the logo  
reading only “Compact Disc/Recordable” are  
designed for computer data recording, and  
they will NOT work in the CDR 20.  
The CDR 20 will not copy DVD discs, computer-  
data discs, CD-based computer or video-game  
discs, or digital audio discs with a sample rate  
that is not compatible with the range of the  
CDR 20s sample-rate converter.  
When you are ready to start the dub, press the  
Dubbing Button l). During this process  
the Dubbing Indicator H will light, the  
Record Indicator T will flash and a BUSY  
message will flash in the Record Decks  
Recordings on the CDR 20 may be made in a  
number of ways:  
Discs may be dubbed using the playback  
deck on the CDR 20 as a source. These copies  
may be made in real time, at twice normal  
speed, or at four times normal playback  
speed.  
Recordings may be made from an external  
CD player or other digital source that is  
synchronized with the dub being made in the  
CDR 20.  
Recordings may be made from any compati-  
ble external digital source.  
Recordings may be made from an external  
analog source.  
Information Display K. When both  
Information Display Indicators return to normal,  
with indications of 0100:00, press the  
Play/Select Button j*˘ to start the dub.  
CD-R discs may not be erased or have  
material added to them once they have been  
finalized.  
At least four (4) seconds of blank recording  
time must remain on an unfinalized disc for  
recording to take place.  
While the dub is in progress, you will see the  
track numbers and running time increase as  
the disc is copied. The Level Indicators will also  
flash but this is only for your reference, as  
record levels may not be adjusted during digital  
recordings. It is possible to listen to the source  
disc while it is being dubbed by selecting the  
appropriate input on your receiver, preamp or  
processor.  
The maximum number of tracks that may be  
recorded on a disc is 99.  
Note that some CD-R/CD-RW audio recording  
discs may be used for single-speed recordings  
only. If you use a disc with such a warning,  
make certain not to make a dub at x2 or x4  
speed. However, the CDR 20 has been tested  
for compatibility with a wide range of blank  
discs from manufacturers throughout the  
world. In most cases, blank discs will produce  
high-quality recordings at any dub speed.  
In some rare cases, a CD player may not be  
compatible with CD-R discs. If you find that a  
CD-R disc plays in some players but not in  
others, the fault is most likely with the player,  
not with the recorded disc or the CDR 20.  
Remember that CD-RW discs made in the  
CDR 20 will play only in CD players that are  
specially designed to accommodate CD-RW  
discs. Note that most DVD players are com-  
patible with finalized CD-RW discs.  
CD-RW discs may not be erased and reused  
more than 99 times. This is a limitation of the  
CD-RW format, not a fault of the CDR 20.  
Important Note: When a high-speed (x2 or  
x4) dub is being made, you will hear the play-  
back from the CDP outputs ¡¢• at the  
faster speed. Fast speed playback increases the  
pitch of a sound, and when played back at high  
volume levels this may damage your speakers.  
DO NOT use high volume levels when listening  
to high-speed dubs while they are in progress.  
Disc Dubbing  
The easiest way to make a copy of an entire  
disc is to use the CDR 20s internal dub  
capability.  
First, insert a blank or unformatted disc in the  
Record Drawer %. When the disc is inserted,  
the CDR 20 will examine it to determine if it  
is a CD-R or CD-RW disc, and optimize itself  
for the best possible recording. This is indicated  
by OPCmessage in the Information  
Display K.  
The dub will stop automatically when the  
source disc has played through to the end. After  
the dub is finished, the Information Display will  
show an UPDATEmessage, and then return  
to normal operation. To manually stop a dub-  
bing operation, press the Stop button  
x&¸ for either deck.  
Place the disc to be dubbed in the Play  
Drawer 3 and wait until the Table of  
Contents data is read and the Information  
Display K shows the track and running time  
data for the disc.  
20 CD RECORDING  
 
CD Recording  
As with all recorded CD-R/CD-RW discs, the  
disc must be finalized before it can be played in  
other machines. See page 22 for instructions on  
disc finalization.  
add track numbers manually by pressing the  
Track Increment button n when you  
wish to increase the track number. This mode  
is recommended for recordings made from  
analog sources.  
The Auto mode will add track numbers auto-  
matically, in one of two ways. When track  
data is present from a digital recording, it will  
be carried over to the new copy disc. Thus,  
when the CD being played moves from one  
track to the next track, the copy disc will also  
increase the track number by one. Activate  
the Auto mode by pressing the Auto/Manual  
button m once and note that the Auto  
Indicator W will light.  
In the Auto mode for recordings from an ana-  
log source or a digital source with no track  
data, the track number will be increased  
when the CDR 20 receives silence for 3 sec-  
onds. After 5 seconds of silence, the recording  
will stop. To activate the Auto mode, press the  
Auto/Manual button m once and note  
that the Auto Indicator W will light.  
To record the entire disc or tape, press the CD  
Sync Button twice so that ALLappears in  
the Record Deck Information Display K.  
When the desired mode has been selected,  
start the playback from the source machine. The  
CDR 20 will automatically recognize the incom-  
ing digital data and begin recording. If the  
source material is a CD, the track numbering  
from the original disc will be carried over to  
the dub. If the playback source is NOT a CD,  
you will have to increment the tracks manually.  
Notes on Dubbing:  
If you wish to make a dub with the tracks in  
a different order from the original disc, omit  
tracks on a disc, or make a dub that mixes  
tracks from different discs, create a Program-  
Playback List before pressing the Play/Select  
button j* to start the dub. Instructions  
for creating a Program List may be found on  
page 18. NOTE: Dubs containing Program  
Lists may be made at either the x1 or x2  
speed. If you attempt to make a Programmed  
Dub at the x4 speed, the unit will automati-  
cally select the x2 speed.  
The recording will continue until the CDR 20  
senses that the playback is finished when there  
in no incoming signal for more than three sec-  
onds. At that point the recording will stop. You  
may also stop the recording at any time by  
pressing the Record Deck Stop button  
x&. When there are only four seconds  
remaining on a blank disc, DISC FULL  
message will appear in the Information  
Display ˚. When you see this message, you  
will need to stop the recording process and,  
when a CD-R is being recorded, insert a new  
blank disc or, when a CD-RW is in use, either  
use a new disc or erase existing tracks follow-  
ing the instructions on page 22.  
The Pause buttons do not operate while a  
dub is in progress.  
Tracks will be added automatically to mirror  
the track structure of the original disc.  
The Total Time indication of the recorded CD  
may vary slightly from the original due to vari-  
ations in the spin speed of each drive, but this  
is normal. No information has been lost in the  
recording process.  
If the original disc being dubbed is a digital  
copy or if it contains copy-prohibit signals, the  
unit will automatically make an analog copy.  
To prepare for a recording, press the Record  
button t8. The Record Indicator T will  
flash, and the word BUSYwill briefly appear  
in the Information Display K. When the  
Display returns to the track and running-time  
information, the unit is ready to record.  
After the recording is complete, an UPDATE  
message will appear briefly, and the unit will  
then return to normal operation. Remember to  
finalize the recorded disc so that it may be used  
in other machines.  
CD Sync Recording  
Once the source material is playing, start the  
actual recording by pressing the Play/Select  
button j*. Note that the Record  
CD Sync recording allows you to make an auto-  
matic digital recording from an external CD  
player or MD. During CD Sync Recording, the  
0record unit starts in sync with the source, and  
tracks are added automatically.  
Recording from an External Source  
To record from an external source, first place a  
CD-R or CD-RW audio disc in the Record  
Deck %. Next, select the input to be used by  
pressing the Input button v. Pressing the  
button will cycle between the input choices,  
which will be shown in the Information  
Display K as COAX, OPTICALor  
ANALOG. In addition, the Digital Indicator  
Y will light when the coax input is selected,  
and the Analog Indicator X will light when  
the analog inputs are selected.  
Indicator T will stop flashing and the  
Information Display K will begin to show  
the running time of the recording and the track  
data. Depending on which mode of track incre-  
ment has been selected as described above,  
track numbers must be increased manually or  
they will be added automatically. Regardless of  
which mode has been selected, a track may be  
added at any time by pressing the Track  
Increment button n.  
To make a CD Sync recording: First, make cer-  
tain your playback source is selected and cued  
to the correct starting point. Next, select the  
appropriate digital input by pressing the Input  
button v until the desired COAXor  
OPTICALindication appears in the Record  
Deck Information Display K. CD Sync  
recordings may not be made from an analog  
input.  
Note: If there is a pause in the playback signal  
for more than 5 seconds for digital recordings  
or 10 seconds for analog recordings, the  
CDR 20 will stop the recording. Also, when the  
Pause button is pressed during a recording, the  
track number will increase by one number and  
the recording will stop and must be restarted  
by pressing the Play/Select button j*.  
When the recording is finished, press the Stop  
button &x.  
Note that when the digital input is selected,  
the connection may be made to either the rear  
panel Coax Input § or the Front-Panel  
Digital Input 6. If a signal is present at both  
coax inputs when a recording is made, the  
front-panel input will be used as the source.  
Next, make certain that there is a fresh disc in  
the Record Drawer for the recording. Press the  
CD Sync button w9 and note that the  
Sync Indicator I will light and the Record  
Indicator T will flash. Select the type of  
recording to be made:

Although the Level Indicator C will operate,  
this is only informative and the level may not  
be changed or adjusted. However, when you  
are making a recording from an external analog  
source such as a cassette recorder or the ana-  
log output of a receiver or preamp, you should  
adjust the input levels using the Record-Level  
Control ^. Adjust the levels so that the

sionally. If the red segments are constantly lit,

other players. The CD Indicator S will  
remain lit.  
Unfinalizing and Erasing CD-RW Discs  
CD-RW discs are unique in that they are both  
recordable and rewritable. This means that you  
may use them over again like a cassette tape.  
However, the process of reusing a CD-RW disc  
is slightly different from that used with tapes.  
To erase only the last track, press the Erase  
button u!. Note that the Information  
Display K will display 01TRKand the  
Erase Indicator V will flash. Press the  
Play/Select button j* within three sec-  
onds and note that the Erase Indicator will stop  
flashing. When the Erase Indicator V goes  
out the Information Display K will show  
the total number of tracks that now remain on  
the disc.  
Unfinalizing a CD-RW Disc  
To keep the material that is already recorded on  
a CD-RW disc but to add an additional track  
and erase single tracks, you must first unfinalize  
the disc. To do that, place the CD-RW disc in  
the Record Deck % and wait until the Table  
of Contents data has been read.  
To stop the recording, press the Stop button  
x&. The recording will automatically stop if  
it takes more space than is available on the  
CD-R/RW disc. A DISC FULLmessage  
will appear to remind you that a new disc is  
needed.  
You may erase more than one track, counting  
backwards from the last track. First, press the  
Erase button u!. Note that the  
Press the Erase button u! twice and  
check to make sure that the Erase Indicator  
V flashes and the word TOCappears in the  
Record Deck Information Display K.  
Within three seconds, press the Play/Select  
button j* to start the process. The Erase  
Indicator V will remain lit and stop flashing,  
and the Information Display K will switch  
to OPCand then back to TOC.  
Information Display will display 01TRKand  
the Erase Indicator V will flash. Press the  
Next button or Previous button  
until the number of tracks to be erased  
appears in the Information Display K. For  
example, when 06TRKappears in the dis-  
play a total of six tracks will be erased, count-  
ing back from the last track on the disc. Next,  
press the Play/Select button j* within  
three seconds of making the track selection and  
note that the Erase Indicator V will stop  
flashing. When the Erase Indicator V goes  
out the Information Display K will show  
the total number of tracks that now remain on  
the disc.  
At the end of a recording, a BUSYmessage  
and an UPDATEmessage will appear briefly,  
and the unit will return to normal operation.  
Remember to finalize the disc after recording so  
that it may be used in other players.  
Finalizing CD-R and CD-RW Discs  
When the process is finished, the Erase  
Indicator V will go out, and the display will  
return to normal. The disc is now ready to have  
single tracks removed or additional tracks  
added.  
Finalizing is a simple process that completes  
the recording of a disc so that it may be used in  
other players. When a recording is finished, a  
disc must be finalized. Once that is done, a  
CD-R disc may not be changed or added to.  
CD-RW discs are “locked” once they are final-  
ized, but they may be unfinalized to permit  
additional recording or erasure.  
Erasing an Entire CD-RW Disc  
Erasing the entire contents of a disc is simple,  
and it does not matter if the disc has been  
finalized or not. To erase the disc, press the  
Erase button u! twice if the disc has  
NOT been finalized and once if it has been  
finalized, so that the word DISCappears in  
the Information Display K and the Erase  
Indicator V flashes. To start the erasure,  
press the Select button j* and note that  
the Erase Indicator V will stop flashing. The  
erasure process takes about a minute, and it is  
complete when the Information Display resets  
to 0000:00 and the Erase Indicator V  
goes out. The disc is now totally erased and  
may be reused.  
Important Note: Tracks at the beginning or in  
the middle of the disc may not be erased until  
all of the tracks after them have been erased.  
To finalize a disc, place it in the Record  
Drawer %. Once the discs Table of Contents  
information has been read and the OPC process  
has been completed, press the Finalize button  
o@ and note that the Finalize Indicator  
U will begin to flash. Within three seconds,  
press the Select button j* and note that  
the Finalize Indicator U will stop flashing.  
Important Note on Erasure and  
Finalization Times: Regardless of the speed  
at which a disc was recorded, the CDR 20 will  
erase and finalize discs at the x4 speed to mini-  
mize the length of the process. However, in  
some cases, it may be necessary for the unit to  
repeat the erasure or finalization due to the  
nature of an individual disc. For that reason, it  
is normal for the time required to complete  
these steps to vary from one disc to another.  
The finalization process will take up to two  
minutes, depending on the length of material  
recorded on the disc. During the finalization  
process the Record Deck will not accept any  
operating commands.  
Erasing a Single Track  
When the finalization process is complete the  
Finalize Indicator U will go out, and the  
R/RW Indicator P will also go out as an  
indication that the disc is now playable on  
The individual tracks on a CD-RW disc may be  
erased one at a time, starting with the last  
track on the disc, or you may erase more than  
one track. Note that before individual tracks
