CONNECTIONS
Rear Panel Connections
MIC INPUT
Channel 1 may be used with either an unbalanced line level signal or a lower level balanced
microphone signal, controlled by the CH 1 SOURCE SELECT switch on the front panel. A female
XLR connector is provided If you choose to use a microphone in Channel 1. An additional 40 dB of
gain is provided for use with low output level mics. Also, 48V phantom power to operate microphones
that contain active electronic circuitry (such as condenser mics) may be supplied by pushing in the
adjacent PHANTOM POWER switch. This is a mono signal input and is routed to both the left and
right channels.
Channel Inputs (1-8)
These inputs are used with either mono or stereo line level signals. A signal source plugged into the
top ( LEFT (MONO)) jack, with nothing plugged into the bottom (Right) jack, will be routed to both left
and right stereo channels. Otherwise, these inputs operate as two separate mono signals or one
stereo signal. Use cables with 1/4" TS plugs.
MAIN EXPAND (IN and OUT)
Use these jacks to chain multiple MX822s together. The MAIN EXPAND OUT jacks of the first mixer
connect to the MAIN EXPAND IN jacks of the next mixer in line, and so on. Use a stereo cable with
1/4" TRS plugs to make the connection. The last mixer in the chain will be the "master" of all the
previous mixers, meaning its MASTER LEVEL control will control the final volume to the output
device via its MAIN OUT connectors.
Note that the MAIN EXPAND OUT connection is brought out from a point in the signal path before
the MASTER LEVEL control, so this control will have no effect on the "slave" mixers located before
the master unit in the chain.
MONITOR OUT
This is an additional unbalanced version of the main outputs, affected by the MASTER LEVEL
control. Use a stereo cable with a 1/4" TRS plug to connect to an auxiliary recorder or other device.
