CP660 six-channel power 

amplifi er is designed for a wide range 
of demanding applications, including 

multi-channel, distributed sound, surround 
and stereo systems. Perfect for applications 
with multi-zone needs, such as cafeterias, 
restaurants, schools and theaters, the CP660’s 
effi cient design allows convenient, cost-effec-
tive, reliable operation in a compact, two-rack-
space format. 

This highly effi cient amplifi er includes a power-
sharing design that provides extra power to 
channels where it’s needed most. A discrete-
component power design employs rugged, 
high-current metal output transistors for 
maximum reliability. The super-quiet, variable-
speed fan operates according to thermal de-
mand, while the front-panel air intakes provide 
the most effi cient cooling in any rack.

The CP660 brings you maximum fl exibility for 
confi guration, with six independent amplifi er 
channels. Each pair of output channels can 
be bridged, using convenient switches on 
the back panel, to provide three, four or fi ve 
channels with higher output power. In addi-
tion, each channel includes its own back-panel 
gain control for convenient system balancing. 
Barrier strip connectors are provided for the 
inputs, and heavy-duty 5-way binding posts 
allow secure output connections. Plus, your 
investment in a CP660 is backed by Crown’s 
unequaled Three-Year, No-Fault, Full Warranty 
that covers everything.
