Redback® A 4480B 8 In to 8 Out Audio Switcher
A 4931 DIP SWITCHES
The A 4931 has a set of DIP switches on the rear which determine how the VOX (voice operated switch) priority functions.
The DIP switches are labelled 1) VOX BOTH, 2) VOX ENABLE, 3) VOX OUTPUT.
Dip switch 3 when set to ON, activates the VOX function. If this switch is in the OFF position the audio from the A 4931
will only override the A 4493 Input Source Wall Plate if the "Local Input" button has been selected on the A 4493 (see
section 6.0 for details). In this mode the Mic and AUX/Music input from the A 4931 will be mixed - there is no priority.
If DIP switch 3 is set to ON then the following VOX priorites result from DIP switches 1 and 2 without the need for the
"Local Input" button to be selected on the A 4493 Input Source Wall Plate.
DIP Switch 1 set to ON: The Mic and AUX/Music input will mix together and either will activate the VOX circuit. The audio
from the A 4931 will then override the A 4493 zone input audio source.
DIP Switch 2 set to ON: The Mic only will activate the VOX circuit and mute the AUX/Music input if used.The audio from
the A 4931 will then override the A 4493 zone input audio source.5.4
