2 – CAM150 / CAM60 CAM150 / CAM60 – 3
2. INTRODUCTION
The CAM150 and CAM60 Paging Amplifiers are 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 CAM150 has a 150 watt power amplifier, and the
CAM60 has 60 watts. Apart from this difference in power
output, the two models are identical in details and operation.
Four combination mic/line inputs are actively balanced,
with individual switchable sensitivity controls for line-level
input, mic-level input, and mic-level input with 24 VDC
phantom power.
Input 1 has voice-activated priority over Inputs 2-4 and the
AUX Input. Inputs 1-4 have switch-activated priority over the
Aux input. A Telephone Paging input is provided on a terminal
strip, with a rear panel volume control, and has voice-activated
priority over all the inputs. The voice-activated priority has an
internal adjustable level control.
The stereo unbalanced RCA Aux inputs are internally
summed to mono, and have an input sensitivity switch to
optimize the input for a CD player, tuner, tape player, or other
auxiliary input. A small speaker can be used to monitor the
auxiliary music program, and its volume adjustment is provided
with a small monitor trim control on the rear panel.
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 CAM150
and CAM60 operate on either 115 or 230 VAC, 50/60Hz,
supplied by a detachable IEC power cord. A voltage selector
switch is accessable from the bottom panel. A rear panel
terminal strip connection is provided for connecting an external
24 VDC backup battery, with a rear panel DC power switch.
An unbalanced signal processing loop is provided on the
rear panel with RCA connectors.
The front panel provides level controls for each Mic/Line
input, Aux, and Master volume, as well as Bass and Treble. An
LED Meter indicates signal strength and output overload. The
Bass and Treble controls provide up to 10 dB of boost or cut at
100 Hz and 10 kHz respectively.
