The CXA120 is designed for continuous duty in speech, music, paging, and sound reinforcement applications demanding high performance, flexible features, and rugged dependability. Screw terminals provide connections for the two, discrete, actively balanced inputs. The main program input is a conventional input, featuring a 0 dB (Main) / -20 dB (Aux) sensitivity switch for lowlevel and high-level input signals. The second telephone/paging input has voice-activated priority over the main program input as well as a volume trim control.

IThe CXA120 provides outputs for 4 ohm loads and for 25 V, 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. Front panel controls include master volume, bass, and treble. The bass and treble controls provide shelving equalization at 100 Hz and 10 kHz. The front panel meter indicates the output signal level, ranging from -20 dB to +6 dB.
