Both models are equipped with six actively balanced combination mic/line inputs as well as individual adjustable potentiometers for line level input, mic level input and mic level input with 24V DC phantom power. Input 1 also offers the flexibility of an integrated transformer for connection to telephone paging systems.
Inputs 1 and 2 are divided into four discrete input sections: a combination XLR/TRS connector, Phoenix connector, or terminal strip. Meanwhile, Inputs 3, 4, 5 and 6 offer both Phoenix connectors and terminal strips. Two pairs of RCA connectors allow unbalanced auxiliary (Aux) signals to enter the amplifier via Aux 1 and Aux 2, both of which are attenuated by a potentiometer on the front of the amplifier.
Two levels of priority can be established on Inputs 1 and 2, initiated with external contact closures or adjustable signal threshold levels. External volume control is possible through a Phoenix connector and user supplied potentiometer. A two-position Phoenix connector allows the internal fault relay to be connected to redundant systems. And, an adjustable pre-announcement chime is also included.
Front panel controls include a level control for each input, a toggle switch for Aux 1 or Aux 2 selection, and one Aux master level control for the selected Aux. Low and high EQ controls offer 12 dB of boost or cut at 100Hz and 10kHz, respectively. A master volume control offers output volume control, while distinctive LEDs indicate power (green), signal (amber), overload (red), and fault (red).
The CAM160 provides 160W of output power at 100V, 70.7V, 25V and 4 Ohms, while the CAM80 offers 80 watts of output for the same power configurations. An intelligent output stage is fully protected against permanent damage caused by overloading, shorts and thermal faults.
Both units operate on 100V to 240V AC power (50/60Hz), and are supplied by a detachable IEC power cord. A combination banana plug/binding post connection is also provided for connecting an external 24V DC backup battery.
