Bogen CAM2 - Manual (Page 7)

Input Connections
Microphone Inputs
Microphones are connected to the CAM2 using the MIC1 through MIC 4 connectors.The CAM2 uses male XLR
type connectors for making connections to its inputs. Microphones typically accept female XLR connectors. Cables
with male and female XLR connectors already attached are commonly available at retail stores or through Bogen.
The figure below shows the connection of various microphones.
Phantom Power
Each MIC input has a PHANTOM switch associated with it.This
switch must be set correctly for the type of microphone being
used with that MIC input. Microphones come in two basic
types: Dynamic and Electret Condenser. When using Dynamic
microphones, set the PHANTOM switch for that microphone
input to OFF. When using an Electret Condenser microphone, set the PHANTOM switch to ON. Elecret Condenser
microphones require a DC voltage to power their internal circuitry.When the PHANTOM switch is set to ON, the
microphone input will supply a DC voltage back to the Electret Condenser microphone through the microphone
cable (this is called providing Phantom Power to the microphone).
If the PHANTOM switch is set to ON when using a Dynamic microphone, you may hear a loud pop every time the
microphones ON/OFF switch is changed. If you do hear this, then check that the PHANTOM switch for that micro-
phone input is set properly.
Output Connections
LINE OUT
Unbalanced inputs are also popular on many pieces of equipment that the CAM2 may feed.
To make the connection as easy as possible, the CAM2 provides an unbalanced LINE OUT
signal that is of the proper signal level to connect to most equipment.An RCA patch cord is
used to make this connection and is commonly available at retail stores. Since this output is
unbalanced, it is important to keep the length of the connecting cable relatively short. Less
than 10 feet is recommended. The figure below shows the general way in which the LINE
OUT of the CAM2 is connected to the unbalanced input of an amplifier.
