MIXERS
The CAM2 is a 5-input mixer/pre-amplifier suitable for a wide variety of applications, particularly for expanding the number
of inputs on Bogen or other public address amplifiers. The CAM2 provides four professional, low-impedance, balanced microphone
inputs through XLR connectors and one auxiliary input.
Individual phantom power switches for each input allow the use of both dynamic and condenser microphones on the
same unit. A bridging input permits simple interconnection of multiple CAM2 mixers for system expansion without the need
to sacrifice any mixer inputs. Clipping indicators for each input and an output level meter provide information to the system
operator about sound integrity. Wide frequency response, low distortion, low noise, and high channel crosstalk isolation ensure
superior sound quality. The CAM2's balanced mixer output can be switched between line-level (+4 dBµ) or microphone-
level (-50 dBµ) for compatibility with a wide range of sound processing equipment.
