CAM160 / CAM80 – 3

2. 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.
