Congratulations on your purchase of a
Crown® CP660 six-channel power amplifier.
The CP660 has been designed to give you
super flexibility and the best watts-to-dollar
ratio around. With six independent channels,
the CP660 takes the place of three, two chan-
nel amplifiers, yet still fits in a standard
two-rack space. Its 75 watts average output
per channel* is ideal for a variety of sur-
round-sound uses, as well as many paging,
zoning, and background music applications.
Plus, when you need it, you can easily bridge
any pair of consecutive channels for double
the power.
•
•
Three Dual/Mono switches on the back
panel give a broad range of flexibility in
configuring your system.
Six-Channel Mode
1 Channel / 1 Load

YOU WILL NEED (not supplied):
CAUTION: Before you begin, make sure
your amplifier is disconnected from the
power source, with power switch in the
“off” position and all level controls
turned completely down (counterclock-
wise).
When using an equipment rack, mount units
directly on top of each other. Close any open
spaces in rack with blank panels. DO NOT
block side or front air vents.

Use a standard 19-inch (48.3 cm) equipment
rack. See Figure 3.1 for amplifier dimensions.
WARNING: Before you start to set up
your amplifier, make sure you read and
observe the Important Safety Instruc-
tions found at the beginning of this
manual.
You may also stack amps without using a
cabinet.
NOTE: When transporting, amplifiers should be
supported at both front and back.

3 Setup
3.4 Choose Input Wire
and Connectors
3.5 Choose Output Wire
and Connectors
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.
NOTE: Custom wiring should only be
performed by qualified personnel.

3.6 WireYour System
3.6.1 Stereo Mode
Typical input and output wiring is shown in
Figure 3.6.
INPUTS: Connect input wiring for each
channel. Maintain proper polarity (+/-) on
input connectors.
OUTPUTS: Maintain proper polarity (+/-) on
output connectors.
Connect Channel 1 positive (+) speaker load
to Channel 1 positive (red) terminal of amp;
repeat for negative (-). Repeat each channel
wiring as for Channel 1.
Figure 3.6. System Wiring, Stereo Mode
3.6.2 Bridge-Mono Mode
Typical input and output wiring is shown in
Figure 3.7.
INPUTS: Connect input wiring to lower-
numbered channel only for each channel
pair.
NOTE: Crown provides a reference of wiring
pin assignments for commonly used connector
types in the Crown Amplifier Application Guide
OUTPUTS: Connect the speaker across the red
binding post of each channel pair. Do not use
the black binding posts of the channel pair
when the pair is being operated in Bridge-
Mono mode.
Figure 3.7. System Wiring, Bridge-Mono Mode
NOTE: Set the level control for the
higher-numbered channel of the chan-
nel pair to zero (0) when operating the
channel pair in Bridge-Mono mode, as
the lower-numbered level control works
both channels.

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)
please refer to the Crown Amplifier

5 Troubleshooting
CONDITION: Normal operation.
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.
