The Bogen CAM8PRO is an 8-input, dual-bus MIC/Line mixer that combines superb performance with a generous
array of simple-to-use features in a single-rack space design. It features 8 independently assignable inputs switchable between MIC and Line. Each input has a trim control, a switchable low-cut filter, and a Main/Auxiliary bus
output selector. An additional Auxiliary input can be routed to the Main output, AUX output, or both by setting
internal jumpers. Phantom Power is provided for condenser microphones.
The CAM8PRO also features a built-in Compressor/Limiter with adjustable Threshold and Ratio Controls. A Bar
Graph Output Meter indicates output signal levels. The CAM8PRO also includes a headphone output. Solidly
engineered, the Bogen CAM8PRO mixer will provide many years of trouble-free operation.
