EAW CXA240 User manual

Part No. SW0142 Rev. B 07/07
DESCRIPTION
The CXA240 is a single channel power amplier designed
for continuous duty in speech, music, paging, and sound
reinforcement applications demanding high performance, exible
features, and rugged dependability. XLR and RCA jacks provide
two-channel connections to the amplier that are mixed internally.
This allows connection of stereo sources or two independently
controlled sources. A single level control adjusts the input
sensitivity for both input channels.
The CXA240 provides outputs for 4 ohm loads and for 70 V and
100 V distributed systems. The output stage is designed with
smart circuitry that protects against permanent damage caused
by overloading, shorts, and extreme temperatures. The front panel
has indicators for power on, signal level, signal presence, peak
(clipping), and protect mode.
The CXA240 operates on 115 V or 230 V AC mains determined by
a voltage select switch. A 24 V DC power input allows connecting
backup battery power with automatic AC to DC switchover in the
event of AC mains failure. Five year warranty.
