NOTE: THE INFORMATION IN THIS MANUAL IS IN-

1.1 The Com-Tech Series
The
Com-Tech
series is a complete family of amplifiers
with a wide range of power output capabilities.
Com-
Tech
amplifiers can directly drive "constant voltage"
lines, so you can avoid the expense, distortion and
insertion loss associated with step-up transformers for
distributed loudspeaker systems.
Com-Tech
amplifi-
ers also utilize Crown's patented
ODEP
®
protection cir-
cuitry, which keeps the amplifier working under severe
conditions that would shut down a lesser amplifier. All
Com-Tech
amplifiers feature Crown's exclusive
P.I.P.
®
(Programmable Input Processor) expansion system.
The
P.I.P.
expansion system makes it easy to tailor
your amplifier to a specific application or to add future
technology as it develops.
1.2 Warranty
Each Reference Manual contains basic policies as re-
lated to the customer. For further assistance please
