esigned from the ground up exclusively
for the professional sound contractor,
Com-Tech® offers incredible features,
D
flexibility, and the best long-term value in
commercial audio today.
IOC® (Input/Output Comparator) circuitry im-
mediately alerts of any distortion exceeding
0.05%, providing dynamic proof of distortion-
free performance.

The Com-Tech 10 Series amps offer the same
features and performance of the original
Com-Techs while delivering upgraded fea-
tures to help make your job easier.

•
Unique power supply allows channels to be
independently operated in either 70-V or 8/4-
ohm mode.
Enhanced PIP2™ (Programmable Input Pro-
cessor) connector accepts new accessory
modules that tailor the amplifier to suit spe-
cific applications.
Remote feature allows amplifier to be turned
on and off from a remote location by adding
an optional R.S.V.P. accessory.
In a profession where unplanned service
calls quickly wipe out profits, Com-Tech 10
Series is designed to be the most reliable
amplifier you can install.
Crown’s Grounded Bridge™ design delivers
large voltage swings without using easily
stressed output-transistor configurations like
conventional amplifiers. The results are
lower distortion and superior reliability.
Full protection from shorted, open and mis-
matched loads; general overheating; DC;
high-frequency overloads, and full protection
from internal fault are provided by our latest
protection scheme: “Quad-Mute.”

•
Patented ODEP® (Output Device Emulation
Protection) circuitry compensates for over-
heating and overload to keep the amplifier
working when others would fail.

Three Year No-Fault Full Warranty completely
protects your investment and guarantees its
specifications.
