2. INTRODUCTION
The CXA120 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 CXA120 offers two discrete inputs with priority. The
main program input is actively balanced and terminated to
screw-terminal connections on the rear panel. The second
input is a telephone/paging input, which is also actively
balanced and terminated to a screw-terminal connection on
the rear panel. The telephone/paging input has voice-activated
priority over the main program input, and has an adjustable
rear panel volume control.
The main input features a 0/–20 dB sensitivity switch for
low-level and high-level input signals.
Output modes include 4
Ω
constant impedance, and
25 V, 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 CXA120
operates on either 115 or 230 VAC, 50/60Hz, determined by
a voltage select switch, and 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 master volume control, and
controls for Bass and Treble. The Bass and Treble controls
provide shelving equalization, with up to 10 dB of boost or cut
at 100 Hz and 10 kHz.
A front panel meter indicates output signal strength,
ranging from –20 dB to +6 dB.
