2. INTRODUCTION

The CXA240 is designed for continuous duty in speech, 

music, paging and sound reinforcement applications in 

churches, schools, offices, arenas, hotel meeting rooms, 

convention centers, recreation facilities and other venues 

demanding high performance, flexible features, and rugged 

dependability.

The CXA240 has a 240 watt power amplifier, with an 

internal output transformer. The outputs are screw terminals 

that accept bare wire or spade terminals.

There are four inputs: two unbalanced RCA, and two 

combination inputs, capable of accepting balanced XLR, 

1/4" TRS, or unbalanced 1/4" TS connections from line-level 

sources. A rear panel level control allows adjustment of the 

input signals.

Output modes include 4

Ω

 low impedance, and 70 V 

and 100 V constant voltage. The smart output stage is fully 

protected against permanent damage caused by overloading, 

shorts, and extreme temperatures.

The CXA240 operates on either 115 or 230 VAC, 50/60Hz, 

determined by a rear panel voltage select switch, and is 

supplied by a detachable IEC power cord.

A rear panel terminal strip connection is provided for 

connecting an external 24 VDC backup battery, with a rear 

panel DC power switch.

The front panel provides a meter that indicates output 

signal strength, ranging from –20 dB to 0 dB and clipping.

Three status LEDs on the front panel show when the 

amplifier has a signal present, when the amplifier is in 

protection mode, and when the peak output is reached.

The front panel incorporates holes for rack mounting, and it 

will take up three rack spaces. There are two handles fitted on 

the front panel.
