CAM160 / CAM80 –
3
. INTRODUCTION
The CAM160 and CAM80 mixer 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 CAM160 has a 160 watt power amplifier, and the
CAM80 has 80 watts. Apart from this difference in power
output, the two models are identical in details and operation.
Six combination mic/line inputs are actively balanced,
with individual sensitivity controls and selection switches for
line-level input, mic-level input, mic-level input with 24 VDC
phantom power, 10 dB pad, and high-pass filtering.
Input 1 and 2 have automatic ducking and manual priority
over the other inputs. They also have a manual selectable
chime, and chime volume. The auto ducking has selectable
ducking threshold and adjustable depth control.
The stereo unbalanced RCA aux inputs are internally
summed to mono, have a front panel aux selector switch and
level control.
An unbalanced signal-processing loop is provided on the
rear panel with RCA connectors.
Output modes include 4 ohm constant impedance, and
constant voltage 25 V, 70 V and 100 V. The output stage is fully
protected against permanent damage caused by overloading,
shorts, and extreme temperatures.
The universal power supply will operate from 100 VAC to
240 VAC, 50/60Hz, supplied by a detachable IEC power cord.
Rear panel terminals are provided for connecting an
external 24 VDC backup battery, with automatic switching if
the AC mains fails.
The front panel provides level controls for each mic/line
input, aux, and master volume, as well as bass and treble
controls. Status LEDs indicate signal present, signal overload,
fault and power on.
