CP660
SIX CHANNEL AMPLIFIER
The Crown®CP660 six-channel power
amplifier 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
efficient design allows convenient, cost-effec-
tive, reliable operation in a compact, two-rack-
space format.
This highly efficient amplifier 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 efficient cooling in any rack.
The CP660 brings you maximum flexibility for
configuration, with six independent amplifier
channels. Each pair of output channels can
be bridged, using convenient switches on
the back panel, to provide three, four or five
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.
