Redback® A 4432 4+4 Channel Mixer
10.8 A 4931 and A 4932 DIP Switch Settings
The A 4931 and A 4932 have a set of DIP switches on the rear which determine how the audio is output.
The DIP switches are labelled 1) VOX BOTH, 2) VOX ENABLE, 3) VOX OUTPUT.
When the A 4931/32 is used with the A 4433 there are only two possible audio output options.
1) The audio from the A 4931/32 microphone input and the line and/or music inputs are mixed together and output to the
A 4433
DIP Switches set as follows: 1-OFF ,2-OFF, 3-OFF
2) The A 4931/32 microphone input has VOX priority over the line and music inputs. I.e. the audio from the line/Music inputs
will be over ridden by the MIc input when a microphone is used.
DIP Switches set as follows: 1-OFF ,2-ON, 3-OFF.
The VOX sensitivity of the microphone is adjusted by the trimpot on the rear of the A 4931/32 labelled "VOX" or "VOX
sensitivity".
