To use the external mute or solo inputs 5 to 15 volts needs to be applied to the control input lines.
Polarity must be followed. These inputs are optical isolated.
The mute control is push on - push off, the talk input is also push on - push off
or latching. The solo switching remains in the soloed state as long as the control voltage is applied.
A jumper is provided on the main pcb that selects either the solo is the DAW or ANA1 input as the
solo input.
All audio signals are unbalanced
Starting with the rev5 pcb the low connection for mute and solo has changed
See the section on headphone setup and the external wiring connections.
