Congratulations on your purchase of a

®
CP660 six-channel power amplifi er.
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 chan-
nel 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 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.
In addition, CP660 amplifi er includes a
number of features which require some expla-
nation before they can be used to their maxi-
mum advantage.
