Crown recommends using pre-built or profes-  
sionally wired, balanced line (two-conductor  
plus shield), 22-24 gauge cables with 6 AWG  
terminal forks, less than 0.31 inch (7.8 mm)  
wide. Unbalanced line may also be used but  
may result in noise over long cable runs.  
Crown recommends using pre-built or pro-  
fessionally wired, high-quality, two- or four-  
conductor, heavy gauge speaker wire and  
connectors. You may use banana plugs, spade  
lugs or bare wire for your output connectors  
(see Figure 3.4). To prevent the possibility  
of short-circuits, wrap or otherwise insulate  
exposed loudspeaker cable connectors.  
Refer to Figure 3.3 for correct connector pin  
assignments.  
Using the guidelines below, select the appro-  
priate size of wire based on the distance from  
amplifier to speaker.

3 Setup  
4 Operation  
3.7 Connect to AC Mains  
4.1 Precautions  
4. Never connect the output to a  
power supply, battery or power  
main. Electrical shock may result.  
Connect your amplifier to the AC mains power  
source (power outlet) with the supplied AC  
power cordset. First, connect the IEC end of the  
cordset to the IEC connector on the amplifier;  
then, plug the other end of the cordset to the  
AC mains.  
Your CP660 amplifier is protected from internal  
and external faults, but you should still take  
the following precautions for optimum perfor-  
mance and safety:  
5.  
Tampering with the circuitry, or making  
unauthorized circuit changes may be  
hazardous and invalidates all agency  
listings.  
1.  
Before use, your amplifier first must be  
configured for proper operation, includ-  
ing input and output wiring hookup.  
Improper wiring can result in serious  
operating difficulties. For information  
on wiring and configuration, please  
consult the Setup section of this  
manual or, for advanced setup tech-  
niques, consult Crown’s Amplifier  
Application Guide available online at  
NOTE: The third prong of this connector  
(ground) is an important safety feature. Do not  
attempt to disable this ground connection by  
using an adapter or other methods.  
6.  
7.  
Do Not operate the amplifier with the  
red Clip LEDs constantly flashing.  
Do Not overdrive the mixer, which will  
cause clipped signal to be sent to the  
amplifier. Such signals will be repro-  
duced with extreme accuracy, and loud-  
speaker damage may result.  
Amplifiers don’t create energy. The AC mains  
voltage and current must be sufficient to deliver  
the power you expect. You must operate your  
amplifier from an AC mains power source with  
not more than 10% variation above or below  
the amplifier’s specified line voltage and within  
the specfied frequency requirements (indicated  
on the amplifier’s back panel label). If you are  
unsure of the output voltage of your AC mains,  
please consult your electrician.  
8.  
Do Not operate the amplifier with less  
than the rated load impedance. Due to  
the amplifier’s output protection, such  
a configuration may result in premature  
clipping and speaker damage.  
2.  
3.  
Use care when making connections,  
selecting signal sources and controlling  
the output level. The load you save may  
be your own!  
Do not short the ground lead of an  
output cable to the input signal ground.  
This may form a ground loop and cause  
oscillations.  
3.8 Startup Procedure  
Use the following procedure when first turning  
on your amplifier:  
Remember: Crown is not liable for  
damage that results from overdriving  
other system components.  
1. Turn down the level of your audio source.  
2. Turn down the level controls of the ampli-  
fier.  
3. Turn on the “Power” switch. The Power  
indicator should glow.  
4. Turn up the level of your audio source to  
an optimum level.  
5. Turn up the Level controls on the ampli-  
fier until the desired loudness or power  
level is achieved.  
6. Turn down the level of your audio source  
to its normal range.  
If you ever need to make any wiring or instal-  
lation changes, don’t forget to disconnect  
the power cord.  
For help with determining your system’s  
optimum gain structure (signal levels)

CONDITION: Distorted sound.  
POSSIBLE REASON:  
POSSIBLE REASON:  
This is normal operation for your amp.  
Input signal level is too high. Turn down  
your amplifier level controls. NOTE: Your  
amplifier should never be operated at  
a level which causes the Clip LEDs to  
illuminate constantly.  
OR  
Amplifer is too hot. Turn down input  
signal level to allow ampifier to return  
to normal operating temperature. Check  
speaker loads for short-circuits or too low  
impedance level.  
CONDITION: No power to the  
amplifier.  
POSSIBLE REASON:  
The amplifier’s “power” switch is off.  
The amplifier is not plugged into the  
power receptacle.  
The amplifier’s high-voltage power supply  
fuse has blown. Fuse NOT user-replace-  
able. Return amp to Crown or an  
authorized Crown Service Center for  
servicing.  
CONDITION: No sound.  
POSSIBLE REASON:  
The amplifier has just been turned on and  
is still in the 4-second turn-on delay.  
No input signal.  
Input signal level is very low.  
Level controls are turned down.  
Speakers not connected.
