EAW Commercial CXA160 Specifications

2 INPUT X 1 OUTPUT 160 W POWER AMPLIFIER

DESCRIPTION

The new EAW Commercial CXA160 power amplier features a
exible input/output design that makes it ideal for stand-alone
operation as well as a convenient solution where additional system
zones need to be added. Specically intended for a wide variety of
installation applications, CXA160 is outtted with both a standard
audio input as well as a dedicated priority input, combining to make
them very cost-eective two-input by one-output units.

Two combination mic/line inputs are actively balanced, with
individual adjustable potentiometers for line level input, mic level
input, and mic level input with 24-volt DC phantom power. Input 1
and the priority input are divided into four discrete input sections:
a combination XLR/TRS connector, Phoenix connector, or barrier
strip. Meanwhile, a Parallel output provides handy “loop-through”
capability - the means to pass un-amplied line level signals
downstream to additional ampliers via barrier strip, Phoenix, 1/4­inch or XLR outputs.

Priority announcements can be initiated with external contact
closures or adjustable signal threshold levels. External volume
control is also possible through a Phoenix connector as well as
a user-supplied potentiometer. Further, a two-position Phoenix
connector allows the internal fault relay to be connected to
redundant systems.

Front panel controls include low and high EQ controls which oer
12 dB of boost or cut at 100 Hz and 10 kHz, respectively. A master
volume control oers output volume control, while distinctive LEDs
indicate power (green), signal (amber), overload (red), and fault (red).

CXA160

Features

• Two combination 1/4-inch/XLR/Phoenix,
or barrier strip Mic/Line inputs

• One parallel output on barrier strip, Phoenix,
1/4-inch or XLR

• Selectable 24-volt phantom power

• Dedicated priority input

• Internal fault-activated relay

• External volume control

• 4-Ohm, 25-volt, 70-volt and 100-volt outputs

• Automatic changeover to 24-volt DC backup power

• Universal power supply

The CXA160 provides 160 watts of output power at 100
volts, 70.7 volts, 25 volts and 4 Ohms. An intelligent output stage is
fully protected against permanent damage caused by overloading,
shorts and thermal faults.

CXA160 operates on 100 volts to 240 volts AC (50/60 Hz) and is
supplied by a detachable IEC power cord. A combination banana
plug/binding post connection is also provided for connecting an
external 24-volt DC backup battery.
