Heritage Audio MCM20.4 - 20 Channel rackmount mixer with subgroups, aux sends and inserts

Heritage Audio MCM20.4 - 20 Channel rackmount mixer 

The Heritage Audio MCM20.4 is a 20 channel rackmount mixer with 16 input channels, two eight channel subgroups and four channels hard wired in left and right pairs. Each input channel has a rotary fader, pan control and switches for balanced insert and mute switches. The unit has four aux sends, one and two being mono and four being stereo. These can be routed pre or post fader. 

The insert send points always have the signal present, so they can be alternatively used as direct outputs for recording without additional patch bays.

Each group has its own stereo fader and balanced insert point and all 4 stereo subgroups are passively summed into the master bus. The gain is restored by means of a 1073 style class A , transformer coupled, mic preamplifier, featuring a total of 4 transformers (2 each channel).

The master section is also provided with its own balanced insert point.

All connections on the back are made by DSUB 25 connectors following the Tascam protocol, with the exception of the master bus connections, which are by dedicated XLRs.
