Unpacking the RSP-975
About Rotel
Your RSP-975 underwent quality control tests before we sent it on
its way to you and should perform perfectly out of the box.
A family whose passionate interest in music led them to manufac-
ture high fidelity components of uncompromising quality founded
Rotel over 30 years ago. Through the years that passion has re-
mained undiminished and the family goal of providing exceptional
value for audiophiles and music lovers regardless of their budget,
is shared by all Rotel employees.
Remove the unit carefully from its packing. Look for the handheld
remote controller and other accessories. Save the packing and
box if possible as it will protect the RSP-975 if you move or need to
return it to us for maintenance.
Placement
The engineers work as a close team, listening to, and fine tuning
each new product until it reaches their exacting musical stan-
dards. They are free to choose components from around the world
in order to make that product the best they can. You are likely to
find capacitors from the United Kingdom and Germany, semi con-
ductors from Japan or the United States, while toroidal power
transformers are manufactured in Rotel’s own factory.
Place the RSP-975 on a solid, dry, level surface away from direct
sunlight, excessive heat, high humidity, or strong vibrations.
Make sure the RSP-975 is close to the other components in your
audio/video system as that makes initial hookup and any subse-
quent troubleshooting easier.
Rotel’s reputation for excellence has been earned through hun-
dreds of good reviews and awards from the most respected re-
viewers in the industry, who listen to music every day. Their
comments keep the company true to its goal - the pursuit of
equipment that is musical, reliable and affordable.
If at all possible, put the RSP-975 on its own shelf. This makes ini-
tial cable routing, hookup, and any subsequent system changes
easier. It also minimizes potential interference or heat buildup
from other components.
Make sure there is enough room behind the RSP-975 for easy
hookup. Remember, you’re connecting many other components to
this unit and you’ll probably need more space than you think.
All of us at Rotel, thank you for buying this product and hope it will
bring you many hours of enjoyment.
Don’t stack other objects (components or other items) on top of
the RSP-975. Don’t let water fall into the RSP-975 as this could
damage delicate circuitry.
Getting Started
Thank you for purchasing our RSP-975 Digital Surround Sound
Processor. The RSP-975 is a full-featured audio/video processor
designed to decode both analog and digital surround sound sig-
nals including Dolby Pro Logic and 5.1 channel Dolby Digital
sources. It will provide accurate reproduction of both movie
soundtracks and demanding musical selections and is a natural
extension of our well-known passion for good sound.
Front Panel Controls
We suggest you look over the RSP-975’s front and rear panels be-
fore you start connecting other components to it. The following
explanations will help you get familiar with the units connections,
features, and controls, with number references corresponding to
the illustrations at the front of this manual.
To get the most from your RSP-975, we suggest you read this
manual and keep it as a reference to answer any future questions.
Most functions are duplicated on the front panel and on the
handheld remote control shipped with your unit. A few may be
available only on one or the other. When two reference numbers
appear, one refers to the location of the button on the front panel,
the other to the location of the button on the handheld remote
control.

VOLUME Display
This button overrides all other input selectors (both analog and
digital) and directly connects an external adaptor (such as Rotel’s
RDA-986 DTS Processor) to the RSP-975’s MASTER VOLUME con-
trol. This allows the RSP-975 to remain the central controller for
even the most advanced audio/video systems. When activated, all
of the RSP-975’s inboard Dolby processing is bypassed.
As you adjust the volume, a digital display located above the con-
trol will provide a volume indication in one decibel steps with
+12dB being maximum output level and –67dB being minimum.
18
TONE Controls
BASS and TREBLE controls increase and decrease the audio
signal’s low and high frequency content. Rotate each one clock-
wise to increase output in the respective frequency range and
counterclockwise to reduce it. The center detent removes each
control from the audio path for maximum signal integrity.
17
SURROUND MODE LEDs
The RSP-975 provides three different surround sound modes to
accommodate different types of audio and video source material
as described below. These LEDs tell you which surround sound
mode you’ve selected. Here is a brief description of the various
surround modes.
5
34
LISTENING SOURCE Buttons
Eight large front panel LISTENING buttons allow you to select an
audio or video source component such as CD, TUNER, VCR, DVD,
etc. Simply push any of these buttons to select an input source.
(The handheld remote has functionally identical buttons.) You will
hear this source and, if you have selected a video source, see its
picture on your TV monitor. An LED indicator on each pushbutton
lights to confirm your selection.
STEREO is a conventional 2-speaker stereo direct bypass mode
with no surround sound or other processing. The FRONT LEFT
speaker, the FRONT RIGHT speaker, and the SUBWOOFER (if
present) are on; all other speakers are off.
DOLBY DIGITAL provides proper playback decoding processing
for any discrete 5.1 channel Dolby Digital encoded digital audio
source such as an AC-3 Laser Disc or DVD disc. Dolby Digital pro-
vides the highest level of surround sound performance with 5
channels of discrete surround information plus subwoofer. Dolby
Digital is only available when using one of the DIGITAL inputs. It is
not available for ANALOG inputs.
Note: As delivered from the factory, pushing one of these buttons
activates the analog audio inputs for each component. However,
to accommodate digital signals available from many source com-
ponents (such as CD players and Dolby Digital DVD players), the
RSP-975 also provides four digital inputs which may be used in-
stead. See below.)
DOLBY PRO LOGIC provides proper playback decoding and pro-
cessing for any Dolby Surround encoded analog audio source,
whether it be a music CD, videotape, videodisc, conventional ste-
reo TV broadcast, or satellite broadcast. Dolby Pro Logic process-
ing and playback through a properly calibrated system will
preserve the directionality, ambiance, and spatial effects intended
by the source’s producers. Dolby Pro Logic can also provide ex-
cellent surround sound playback of musical recordings.

DIGITAL INPUT Button
/ INPUT LEDs
In addition to analog audio inputs for each of eight source compo-
nents, the RSP-975 provides DIGITAL INPUTS for up to four digital
audio sources. These four DIGITAL INPUTS can be assigned to
any of the eight LISTENING inputs

SURROUND MODE Button
PEAK LED
The SURROUND MODE button is used to select one of three sur-
round modes (Dolby Pro Logic, Dolby Digital, or Stereo) as de-
scribed in the section immediately above. To make a selection,
press the SURROUND MODE button. Each time you press the but-
ton, the mode will cycle to the next available setting as indicated
by the SURROUND MODE LEDs.
This front-panel LED lights to indicate that the input signal of the
selected source may be overloading the input circuitry of the
RSP-975. Momentary occasional flashes of this LED on signal
peaks are acceptable. However, if the LED repeatedly or continu-
ously lights, you should reduce the input level for that source.
8
REMOTE LED
NOTE: If an ANALOG input is selected, the only available surround
mode options are DOLBY PRO LOGIC and STEREO. All three op-
tions are available for DIGITAL inputs.
This front-panel LED lights to indicate that a command is being re-
ceived from the handheld remote control.
6
DYNAMIC RANGE LED
The surround mode selection for ANALOG inputs (STEREO or
DOLBY PRO LOGIC) is memorized as soon as it is made for each
LISTENING INPUT and will be automatically engaged the next
time that LISTENING INPUT is selected.
Today’s digital sources are capable of extremely high dynamic
range (the difference between the softest and loudest sounds). In
some cases, the available dynamic range may tax the amplifiers
or speakers. In other cases, it may be desirable to reduce the dy-
namic range, for example, when listening at low volume levels.
The RSP-975 provides the capability to reduce the dynamic range
in three progressive steps (25% / 50% / 75% reduction) with a
pushbutton on the handheld remote control. See the Remote Con-
trol section of this manual for details.
The surround mode setting for DIGITAL INPUTS is not memorized
and is only a temporary override as long as that LISTENING INPUT
is activated.
Every time a DIGITAL INPUT is selected, the surround mode set-
ting will default to DOLBY DIGITAL. If a digital signal is detected
that is not DOLBY DIGITAL, the mode will automatically switch to
DOLBY PRO LOGIC. [???? Is this auto-sensing in the RSP-975?]
This front-panel LED lights to indicate that the dynamic range has
been reduced.
16
11
INPUT LEVEL Buttons
DIGITAL LOCK LED
These two pushbuttons allow you to adjust the level of each
source component so that the volume level remains relatively
constant when switching between source components.
The RSP-975 digital circuitry can lock onto digital signals with a
number of different sampling rates. The DIGITAL LOCK LED lights
to indicate that the digital circuitry has recognized and locked
onto a digital signal.
NOTE: The INPUT LEVEL adjustments only effect the ANALOG in-
put for each source. They have no effect on the DIGITAL inputs.
RR-939 Remote Control
To reduce the input level of the selected source, press the INPUT
LEVEL < button. To increase the level of the selected source press
the INPUT LEVEL > button. As the setting is adjusted, the VOLUME
DISPLAY changes to show the INPUT LEVEL. The range of the ad-
justment is from 0dB (full gain) to –12dB.
The RSP-975 includes a handheld remote control that does far
more than operate the RSP-975. The RR-939 is a full-function pro-
grammable remote control that can operate 8 A/V components.
The setting is memorized as soon as it is made so that it will auto-
matically be recalled whenever that source component is se-
lected.
A separate manual, included with the remote, gives detailed infor-
mation on programming and using the RR-939 to replace all of the
remote controls in your system. This section is intended to provide
only that information which pertains to the use of the RR-939 to
operate the RSP-975.
Note: For optimum performance, it is important not to set the
source input levels so high that the signal overloads the RSP-975’s
input circuitry. If the PEAK LED on the front panel is repeatedly
flashing, adjust the input level for that source downward.
Note: Many functions duplicate the RSP-975 front panel controls
and are listed here only for your reference. Please refer to the
previous Front Panel Controls section of this manual if you need
additional information.
10
MUTE LED
This front-panel LED lights to indicate that the output of the
RSP-975 has been muted from handheld remote control.
To operate the RSP-975 with the remote, make sure that the AU-
DIO mode is active by pressing the AUD button on the remote be-
fore you start. If it is active, pressing command keys on the RR-939
will cause the AUDIO button to flash red. Once the AUDIO mode is
active, it will stay active unless you press one of the other DEVICE
buttons to control a different component.

DIGITAL SURROUND SOUND PROCESSOR RSP-975
Programming the RR-939
SELECT Button (Digital Input) 40
The RR-939 is preprogrammed from the factory to operate the
RSP-975. Should the AUDIO command set on your RR-939 not op-
erate the RSP-975, it’s possible that the programming had been in-
advertently changed. To reprogram the remote to operate the
RSP-975:
Duplicates the DIGITAL INPUT button on the front panel. Selects
the ANALOG input or one of the DIGITAL inputs for the currently
selected source.
32
SURROUND + Button
1. Press the AUDIO button at the top of the remote while simulta-
neously pressing the MUTE button and hold both for at least one
second. The AUDIO button will light in red for 20 seconds, indicat-
ing that you have entered the program mode. The next step must
be done within this 20 second period, or the RR-939 will revert to
its standard operating mode.
Duplicates the function of the front-panel SURROUND MODE but-
ton. Steps sequentially through various surround sound operating
modes. Your current selection will be indicated by front panel
LEDs and will be memorized for ANALOG inputs.
38
SURROUND DELAY Button (remote only)
2. Use the NUMERIC buttons to enter the 3-digit code (001) for the
RSP-975 – press 0, then 0, then 1. The AUDIO button will flash
each time you enter a digit.
The surround processing in the RSP-975 delays the signal sent to
the rear surround speakers as a means of simulating a larger
physical space (such as a movie theater or concert hall) and to
ensure that sounds from the front speakers reach your ear first.
The SURROUND DELAY button steps sequentially through four
available settings for your selected surround mode (not applicable
in STEREO modes).
3. Store the code number by pressing the corresponding AUDIO
button again. The button will blink twice to confirm the storage of
the code in memory.
30
POWER Switch
NOTE: The SURROUND DELAY setting is system-wide. Changing it
will increase or decrease the relative delay time for all inputs and
both surround modes. The setting is automatically memorized as it
is made.
Duplicates the function of the Standby Switch on the front panel.
Press to activate the RSP-975. Press again to deactivate.
29
MASTER VOLUME Controls
You will get visual confirmation of your delay time setting on the
VOLUME DISPLAY as you adjust the setting. The delay time setting
also appears in the ON-SCREEN DISPLAY (see below).
A pair of buttons which duplicate the function of the front panel
volume control. Press VOLUME DOWN to reduce the volume and
press VOLUME UP to increase the volume.
There are no hard and fast rules for setting proper delay times.
Many listeners will be satisfied with the default settings. Others
will want to experiment. In the end, it is a matter of personal taste.
The VOLUME UP/DOWN buttons are also used in making certain
system configuration settings.
In general, longer delay time settings will tend to create the illu-
sion of a larger acoustic space, although if overdone, the effect
can be exaggerated and unnatural. Longer delay settings may
typically be more spectacular. Shorter delay times may be more
natural.
34
SELECTOR Buttons
A group of ten buttons which duplicate the function of the LIS-
TENING SOURCE SELECTOR buttons on the RSP-975 front panel.
Select any input source by pressing the appropriate button.
Delay times also may need to be adjusted depending on the rela-
tive distance from the listening position to the front and rear
speakers. As a general rule, your attention should never be drawn
to the surround speakers as a primary sound source, particularly
when listening to music. If you are closer to the rear speakers, in-
creasing the delay time may prevent this problem.
The labels on the remote buttons match the front panel buttons,
except that the button labelled PHONO/LD corresponds to the
front panel DVD input button and the button labelled AUX 1 corre-
sponds to the front panel AUX input button. The remote buttons la-
belled AUX 2 and TAPE 2 are not used with the RSP-975.
The four DELAY TIME choices for each surround mode are:

will disappear after all six speakers have been highlighted and
you may need to re-enter the menu by pressing and holding the
BACK button.
36
CENTER DELAY Button (remote only)
The CENTER DELAY button works like the SURROUND DELAY but-
ton above, except that it increases the delay the center channel
speaker, if present. CENTER DELAY is only available in Dolby
Digital surround mode. The CENTER DELAY button steps sequen-
tially through five available settings (O, 1, 2, 3, 4, 5 ms).
While seated in the normal listening location, switch the test tone
to the various speakers and listen to hear if any are noticeably
louder or quieter than the front speakers. If so, adjust the quieter
speakers volume levels up or down to match the louder speakers
using the VOL UP/DOWN remote buttons, while the speaker you
wish to adjust is highlighted. Continue switching among the
speakers and adjusting until all of the speakers are approximately
the same volume (or to suit your listening preference).
NOTE: The CENTER DELAY setting is system-wide. Changing it will
increase or decrease the relative delay time for all inputs in Dolby
Digital surround mode. The setting is automatically memorized as
it is made.
This setting will be memorized when you leave the menu and will
become the system-wide default setting.
You will get visual confirmation of your delay time setting on the
VOLUME DISPLAY as you adjust the setting. The delay time setting
also appears in the ON-SCREEN DISPLAY (see below).

ENTER/OUTPUT BALANCE (remote only)
The ENTER button on the remote control has a similar function to
the BALANCE CHECK calibration described above, except that its
adjustments are temporary and apply only to the selected source
input. As soon as you select a different source, the settings revert
to the system-wide defaults as set during the BALANCE CHECK
calibration.

DYNAMIC Button (remote only)
This button is used to reduce the dynamic range to accommodate
program material that could tax your system or for low-volume lis-
tening. This feature is only available in Dolby Digital surround
mode.
Press the button repeatedly to step through the four available set-
tings: NONE (full dynamic range), 25% reduction, 50% reduction,
and 75% reduction. While making the adjustment, the setting will
appear in the VOLUME display. The setting is also shown in the
ON-SCREEN DISPLAY (see below).
NOTE: Although these adjustments can be made directly using the
ENTER button, we strongly recommend that you only make these
adjustments from the ON-SCREEN DISPLAY system. For this rea-
son, the instructions are included in the section on the ON-
SCREEN DISPLAY (see below).
A front-panel LED lights to indicate that the dynamic range has
been reduced.

BACK/BALANCE CHECK (remote only)
The BACK button on the remote control is used during initial cali-
bration of relative speaker volume levels. Generally, it is only used
during initial setup of the system and not during normal operation.
35
ON-SCREEN Button (remote only)
To enter the BALANCE CHECK calibration, press and hold the
BACK button for 2 seconds. The following screen will appear on
your TV monitor, for adjusting the relative volume levels of the
front, center, and rear speakers, along with the subwoofer.
Push this button to turn on the ON-SCREEN DISPLAY. If the ON-
SCREEN DISPLAY is already visible, push this button once or twice
to cancel the display. See next section for details.
When the menu appears, the L/F speaker label will be flashing and
you will hear a test tone coming from that speaker. You can select
the other speakers by sequentially pressing the BACK button. The
test tone will shift accordingly to the selected speaker. The menu

OUTPUT BALANCE Screen
The On-Screen Display
The RSP-975 features two ON-SCREEN DISPLAY screens to help
operate the system. These screens are available at any time by
pressing the ON-SCREEN MENU button on the remote control to
activate the first screen. Push the button a second time to go to
the second screen (OUTPUT BALANCE). Push the button a third
time to cancel the ON-SCREEN DISPLAY.
MAIN Screen
The OUTPUT BALANCE screen provides a temporary adjustment
to the relative output levels of each speaker in the system. Unlike
the BALANCE CHECK calibration procedure, the changes made on
this screen are temporary. They change the output balance only
for the current source input and only until a different source is se-
lected, when the settings will revert to the system-wide default
established during the BALANCE CHECK calibration.
SPEAKER OUTPUT LEVELS: The main portion of the screen con-
sists of labels for each of the speakers in the system, along with
an output level setting. The screen above shows ALL possible
speakers as would appear in a full system in Dolby Pro Logic
mode. Depending on your system configuration and surround
mode setting, you will see a smaller complement of speakers. For
example, in STEREO mode, you will only see FRONT speakers (and
the SUBWOOFER, if your system is configured for a subwoofer).
The MAIN menu provides status information and configuration op-
tions for the source inputs and other system parameters. Some of
the items shown above will not be available for all surround
modes. For example, C DELAY and DYNAMIC will only appear in
DOLBY DIGITAL mode.
INPUT: Two lines showing the currently selected input source and
the audio input for that source. Change the source using the LIS-
TENING SOURCE SELECT buttons on the front panel or remote.
Change the audio input using the DIGITAL INPUT button on the
front panel or the SELECT button on the remote.
To adjust the output of your speakers:
1. Press the ENTER button on the remote. The first speaker label will
flash. Adjust its output level up or down with the VOLUME controls
on the front panel or remote.
S MODE: The currently selected surround mode. Change using the
SURROUND MODE front panel button or the SURROUND + button
on the remote.
C DELAY: The current center channel delay setting, only shown in
Dolby Digital surround mode. Adjust using the C DELAY button on
the remote.
S DELAY: The current surround delay setting, only shown in Dolby
Digital and Dolby Pro Logic surround modes. Adjust using the SUR
DELAY button on the remote.
2. Press the ENTER button on the remote again to move to the next
speaker. Adjust its output level, and press the ENTER button again
to continue the process until all speakers have been adjusted.
3. Press the ENTER button on the remote again to move to the next
speaker. Adjust its output level, and press the ENTER button again
to continue the process until all speakers have been adjusted.
DYNAMIC: The dynamic range setting, only shown in Dolby Digital
surround mode. Adjust using the DYNAMIC button on the remote.
5.1 CH INPUT: whether or not the 5.1 channel input is active
VOLUME: Duplicates the front panel VOLUME display, along with a
bar graph volume indication. Adjust using the VOLUME controls
on the front panel or remote.
4. Once you’ve started adjusting, the screen will return to the MAIN
screen after 5 seconds of inactivity or when you press ENTER af-
ter the final speaker.
NOTE: You can reset the temporary OUTPUT BALANCE settings to
0dB for all speakers at any time by pressing the RECALL button on
the remote control.
Press the ON-SCREEN MENU button a second time to go to the
next screen:
S MONO: This indication appears in the screen only in DOLBY PRO
LOGIC surround mode to indicate that the surround speakers re-
produce a mono signal in this mode.

RSP-975
INPUT: This indication appears only when an ANALOG source in-
put is selected. It shows the current INPUT LEVEL setting for the
active source input and can be adjusted with the front panel IN-
PUT LEVEL buttons. This change is not temporary. It is memorized
and will be recalled each time that source input is selected.
To take full advantage of the built-in digital decoding capability,
the RSP-975 accepts digital signals from up to four different
source components in a number of formats. The digital inputs are
as follows:
OPTICAL: This input allows connection of a standard optical digi-
tal output from a CD player or other source component. Requires
an optical digital cable.
Rear Panel Input Connections
COAX 1 and COAX 2: Two standard coaxial digital connectors for
use with the digital output of any component (CD player, Satellite
TV, etc.)
This section of the manual provides complete information on all of
the audio and video signal input connections on the rear panel of
the RSP-975. For convenience, each topic begins with an over-
view of the particular connection, followed by detailed hookup in-
structions.
DVD: Standard coax digital connection for use with Dolby Digital
DVD players.
To use the digital inputs, simply connect the appropriate cable
from the digital output of your source component to the corre-
sponding digital input on the RSP-975.
Note: DO NOT plug any system component into an AC source until
system hookup is complete. Wait to apply power until you’re con-
fident that all component-to-component connections have been
properly made.
It is necessary to select the appropriate digital (or analog) input
for each component. Once the selection is made, it is memorized
so that simply selecting a SOURCE INPUT activates the appropri-
ate audio input. This procedure is detailed in the DIGITAL INPUT
button section of this manual.
All video and digital audio cables should have a 75 ohm imped-
ance rating. Because the video and digital cable standards are as
close as they are, you can safely use a video cable for digital au-
dio data transmission and, conversely, a digital audio cable for
video data transmission. We strongly advise that you NOT substi-
tute a conventional analog audio interconnect cable for either
digital or video.
20
5.1 CH INPUT
This 25-pin input connects six discrete channels of analog infor-
mation from an outboard processor (DTS, for example).
External adaptors may provide both RCA and DB25 outputs. We
suggest that you use a DB25-to-DB25 cable to reduce the number
of cables and to insure proper channel-to-channel continuity.
26
Source Inputs
These eight sets of RCA-type inputs (TUNER, CD, TAPE, AUX, DVD,
VIDEO 1, VIDEO 2, and VIDEO 3) accept line level audio and com-
posite video signals from source components. The first four inputs
are audio-only, the other four source inputs accept both left and
right channel audio plus a video signal.
If your external adaptor does not have a DB25 output, you will
need to purchase a multi-RCA to DB25 adaptor cable from your
Rotel retailer. Make sure to observe proper channel continuity.
All RCA-type connections on the RSP-975 follow these standard
color codes:
22
REMOTE EXTERNAL IN Jack
This 3.5 mm jack accepts a remote infrared sensor which dupli-
cates the function of the front panel IR sensor in installations
where the front panel sensor could be blocked by a cabinet. See
your authorized Rotel dealer for a selection of remote sensors that
will work with your RSP-975.

Connect the OUTPUTS of your source components to the appro-
priate INPUTS on the RSP-975. For example, if your system in-
cludes a CD player, connect its left and right channel analog
outputs to the RSP-975’s CD inputs. If your system includes a video
source, connect its analog audio outputs to one of the RSP-975’s
VIDEO audio inputs and its video composite RCA output to the cor-
responding composite RCA video input.
Rear Panel Output Connections
This section of the manual provides complete information on the
audio and video signal output connections on the rear panel of the
RSP-975 which are used for routing the output signals to a televi-
sion monitor, audio amplifiers, and recording devices. For conve-
nience, each topic begins with an overview of the particular
connection, followed by detailed hookup instructions.
24
Digital Inputs
The RSP-975 features a D/A conversion capability which allows it
to accept digital input signals from source components. These in-
clude digital signals from CD players, satellite TV receivers, and
5.1 channel Dolby Digital signals from DVD players. The D/A auto-
matically senses and adjusts to the correct sampling rates.

Source Outputs
Rear Panel Configuration Switches
Four of the input sources have corresponding sets of RCA output
connections for routing the signal of the RSP-975 to audio or video
tape recorders for recording.
The RSP-975 has five switches that must be set according to your
particular system configuration. Details follow:
TAPE provides a stereo pair of audio outputs. Connect standard
RCA cables from the LEFT and RIGHT outputs to the LEFT and
RIGHT record inputs on your audio tape recorder.
23
NTSC/PAL Video Switch
There are two different video standards used in different parts of
the world. In the United States, broadcast TV and video compo-
nents adhere to the NTSC standard. In Europe, the PAL standard
is more common. These differ in their technical details (scanning
frequency, etc.) and are not interchangeable.
VIDEO 1, VIDEO 2, AND VIDEO 3 include left and right channel au-
dio plus composite coax video output from the RSP-975 to VCRs or
other components (VCR, etc.) for recording. Standard color coding
applies.
Connect the RSP-975's VIDEO 1 left and right audio outputs to the
audio inputs of the first source component. Then, connect the
VIDEO 1 composite video output to the video input of the same
source component. Repeat these steps for Video 2 and Video 3
connections, if necessary/
You must set the rear panel switch to match the video standard in
your country. If set incorrectly, the video signal sent to your TV
monitor will be unrecognizable.
19
SPEAKER CONFIGURATION Switches
Once properly connected, whatever input signal is selected by the
LISTENING INPUT SOURCE buttons is available for recording at
any or all of the output connections.
There are four speaker configuration switches on the RSP-975’s
rear panel — CENTER (small/none/large), FRONT (small/large),
REAR (small/large), and SUB (on/off). These switches let you cus-
tomize the RSP-975’s main outputs to precisely match system con-
figuration and speaker capabilities.
NOTE: Only analog audio signals are available at the record out-
puts. Therefore, even if you choose to use digital signals from
your source components, you should also connect their analog
signals to the RSP-975, for recording purposes.

Main Audio Outputs
These six outputs (LEFT FRONT, CENTER FRONT, RIGHT FRONT,
LEFT SURROUND, RIGHT SURROUND, and SUBWOOFER) connect
the RSP-975's main audio output to a multichannel power ampli-
fier or multiple power amplifiers for the primary listening area via
six individual RCA-style jacks.
These switches are crucial to proper system configuration and
must be adjusted so that you enjoy all the performance your sys-
tem can deliver.
Standard color coding applies with black insets to distinguish
center channel and subwoofer outputs from left (white) and right
(red) Front and Rear outputs.
Home theater speaker systems vary considerably in their size and
performance, particularly in their bass output. For this reason,
today’s surround sound processors feature elaborate logic which
can send thunderous bass information from movie soundtracks to
the speaker(s) best able to handle it – subwoofers and/or large
speakers. For optimum surround sound performance, it is neces-
sary to tell the RSP-975 what speakers your system includes and
what type they are.
To hook up the RCA main audio outputs, connect a standard audio
cable from each output to the input of the amplifier channel that
will power the corresponding speaker. In a full home theater sys-
tem, you will need to make six different connections correspond-
ing to the six speakers (LEFT FRONT, CENTER FRONT, RIGHT
FRONT, LEFT SURROUND, RIGHT SURROUND, and SUBWOOFER).
The following configuration instructions refer to LARGE and
SMALL speakers. The size refers more to the bass performance of
the speaker than its physical size. A full-range speaker that has
extended bass response is considered LARGE. A compact
minispeaker with limited bass response or power handling is con-
sidered SMALL.
It is important to make sure that you have the correct output con-
nected to the proper amplifier channel. Take your time.
21
MONITOR TV Output
The video output of the RSP-975 sends the video signal to your TV
monitor from an RCA-type composite video connection. Simply
connect the MONITOR TV output to a video input on your televi-
sion monitor, using a standard RCA composite video cable. What-
ever signal is selected on the RSP-975 will appear on screen.
While understanding the terms LARGE and SMALL is useful, it is
probably more important to understand what these different
speaker types mean in terms of system performance. This will
help determine how you should configure your system. In a nut-
shell, the system will redirect bass information away from
SMALL speakers and send it to the LARGE speakers and/or the
SUBWOOFER in your system.
14
RSP-975
Things become a little more complex in systems with a subwoofer.
For example, the system will generally not redirect bass informa-
tion away from a LARGE speaker to the subwoofer. Thus, the de-
cision you need to make when confronted with a choice of LARGE
or SMALL is whether or not you want the particular speaker to
play the deep bass information or whether your would prefer that
the deep bass information be sent to the subwoofer. If you have
invested in a robust subwoofer for your system, you might very
well decide to send all of the bass to it, regardless of how capable
the other speakers in the system may be. In this case, you would
tell the RSP-975 that all of your speakers are SMALL, without re-
gard to how big they may actually be.
25
AC Outlets
These two outlets lets you plug AC cords from source components
or other accessories into the back of the RSP-975 so that they will
be turned on and off automatically. The outlets are powered
whenever the RSP-975 is fully active and are off when the
RSP-975 is in STANDBY mode.
Note: We DO NOT RECOMMEND that you use this outlet for a
power amplifier. Do not exceed the maximum 800 watt capability
of these switched outlets.
An alternative configuration for setting up front SMALL speakers
with a subwoofer would be to follow the speaker manufacturer’s
instructions, wiring the SMALL speakers to the subwoofer’s
crossover and then connecting the subwoofer directly to the front
speaker connection terminals. In this arrangement, the speakers
would be classified as LARGE and the subwoofer setting would be
OFF for all surround modes. No information will be lost during
playback because the system knows to redirect the bass informa-
tion to the front LARGE speakers. This configuration may be opti-
mal for many users as it can improve the way the bass integrates
into the listening room and ensure correct satellite speaker op-
eration by using the speaker manufacturer’s own crossovers.
