IMPORTANT

The CP660 amplifi er requires Class 2 output
wiring.

MAGNETIC FIELD

CAUTION! Do not locate sensitive high-gain equip­ment such as preamplifi ers or tape decks directly
above or below the unit. Because this amplifi er has
a high power density, it has a strong magnetic fi eld
which can induce hum into unshielded devices that are
located nearby. The fi eld is strongest just above and
below the unit.

If an equipment rack is used, we recommend locating
the amplifi er(s) in the bottom of the rack and the
preamplifi er or other sensitive equipment at the top.

WATCH FOR THESE SYMBOLS:

The lightning bolt triangle is used to alert the user
to the risk of electric shock.

The exclamation point triangle is used to alert
the user to important operating or maintenance
instructions.

FCC COMPLIANCE NOTICE

This device complies with part 15 of the FCC rules. Operation is subject to the following
two conditions: (1) This device may not cause harmful interference, and (2) this device
must accept any interference received, including interference that may cause undesired
operation.

CAUTION: Changes or modifi cations not expressly approved by the party responsible for
complicance could void the user’s authority to operate the euqipment.

NOTE: This equipment has been tested and found to comply with the limits for a Class
B digital device, pursuant to part 15 of the FCC Rules. These limits are designed to
provide reasonable protection against harmful interference in a residential installation. This
equipment generates, uses, and can radiate radio frequency energy and, if not installed
and used in accordance with the instruction manual, may cause harmful interference to
radio communications. However, there is no guarantee that 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 encouraged to try to correct the interference by one or more of the following measures:

CP660 six-channel power amplifi er.

Crown
The CP660 has been designed to give you
super fl exibility and the best watts-to-dollar
ratio around. With six independent channels,
the CP660 takes the place of three, two chan­nel amplifi ers, yet still fi ts in a standard
two-rack space. Its 75 watts average output
per channel* is ideal for a variety of sur­round-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.

In addition, CP660 amplifi er includes a
number of features which require some expla­nation before they can be used to their maxi­mum advantage.

Please take the time to study this manual so
that you can obtain the best possible service
from your amplifi er.

* 6 channels into 4-ohm loads.

a wide range of applications.

• Six independent level controls on the back
panel allow convenient level balancing of

• Three Dual/Mono switches on the back
panel give a broad range of fl exibility in
confi guring your system.

• High-quality, standard-spaced double
banana-jack/binding-post output connec­tions facilitate any type of speaker connec­tion, including heavy-gauge wire.

• Super-quiet, variable-speed fan with auto
trigger for silent, effective cooling.

• Compact design is rack-mountable in two
rack spaces (31/2 inches/89 mm).

• The best Three-Year “No-Fault” Fully
Transferable Warranty in the business. It
even covers round-trip ground shipping in
the U.S. for all warranty work.

1.2 Unpacking Your Amplifi er

CP660 Power Amplifi er

3.1 Unpack Your Amplifi er

YOU WILL NEED (not supplied):

• Input wiring cables

• Output wiring cables

• Rack for mounting amplifi er (or a stable
surface for stacking)

WARNING: Before you start to set up
your amplifi er, make sure you read and
observe the Important Safety Instruc­tions found at the beginning of this
manual.

3.2 Install Your Amplifi er

CAUTION: Before you begin, make sure
your amplifi er is disconnected from the
power source, with power switch in the
“off” position and all level controls
turned completely down (counterclock­wise).

Use a standard 19-inch (48.3 cm) equipment
rack. See Figure 3.1 for amplifi er dimensions.

You may also stack amps without using a
cabinet.

NOTE: When transporting, amplifi ers should be
supported at both front and back.

3.3 Ensure Proper Cooling

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.
