CONTROL DESCRIPTION

As well as a transparent and precise signal path the CMC2 Compact Monitor
Controller incorporates many impressive features which are invaluable to the sound
engineer when listening to and examining the quality of the audio.

inputs are heard at the

Speaker Outputs 

(7)

 and Headphones 

(5)

. Each can be operated individually or

simultaneously and in any combination. W hen operated simultaneously the
individual signals are summed into a single stereo signal. Note that the CMC2
does not provide individual level trims for the I/P1 and I/P2 inputs and so any level

matching should be applied before it reaches the CMC2.

An 

AUX

 3.5mm stereo jack input is located on the front panel 

(1b)

 to allow easy

access to connect a MP3 player, smartphone or similar audio device. A control
knob 

(1a)

 allows the adjustment of the 

AUX

 volume to match the system level.
