CAM2 mixers
The Bogen Model CAM2 is a 5-input mixer/pre-amplifier that meets a wide variety of applications.
The CAM2 is particularly well-suited 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 allows for simple interconnetion of multiple CAM2 mixers for system expan-
sion 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 dis-
tortion, low-noise and high channel crosstalk isolation ensure superior sound quality. The CAM2’s balanced
mixer output can be switched between line level (+4 dBu) or microphone level (-50dBu) for compatibility to
a wide range of sound processing equipment.
The CAM2 is listed by UL and C-UL.
The unit may be rack-mounted with a Model RPK35B Rack Panel Kit (1or 2 rack spaces high), or vertically
in-wall mounted with a Model WMK1Wall Mounting Kit.The CAM2 operates from 120V AC, 60Hz.

The unit shall be a Bogen Model CAM2 or approved
equivalent. It shall operate from 120V AC, 60Hz.
Inputs shall be provided for four balanced, low-
impedance microphones and one high-impedance,
high-level, auxiliary sound source. All microphone
inputs shall use XLR connectors and have individual
phantom power switches. Each input shall include a
front-mounted clip indicator and the main output
shall be monitored by a 5 segment LED meter. The
pre-amplifier shall incorporate active mixing to mini-
mize both mixing bus noise and interaction between
channel gain controls, while providing exdellent
crosstalk isolation between channels.The pre-ampli-
fier shall provide a balanced output that can be
switched between providing a line level or micro-
phone level output signal.A separate unbalanced line
level output shall be provided. A bridging input shall
be provided that allows multiple CAM2 units to be
interconnected without the need to use any of the
MIC or AUX inputs. Operating parameters shall be as
set forth in the Technical Specifications table above.
