Volume commands
Use these commands to control volume levels for both inputs and outputs. Input
levels are typically adjusted to minimize drastic changes in volume when switching
between inputs.
Command Description
Mute/un-mute
[MUTEx] Mutes or un-mutes Master Audio output.
x = 0 to disable mute and 1 to enable mute.
x = ? to request current state.
x
= (left blank) to toggle current state.
Adjust volume Level
[VOLoox] Adjusts Master Audio or microphone volume level.
oo = 01 for Master Audio or 02 for microphone.
x = + (plus sign) to increment output volume.
x
= – (minus sign) to decrement output volume.
x = @ to return output volume to factory default.
x = ? to request current volume level.
Adjust volume level—simultaneous
[VOLx] Adjusts Master Audio and microphone volume level.
x
= + (plus sign) to increment output volume.
x = – (minus sign) to decrement output volume.
x = @ to return output volume to factory default.
x = ? to request current volume level.
Set volume level
[VOLooxxx] Sets the volume level to a specific value.
oo = 01 for Master Audio or 02 for microphone.
xxx = -550 to 090
090 equals maximum gain (+9dB), 000
equals factory default (unity gain), and
-550 equals minimum gain (-55dB).
Adjust volume level—left
[VOLLoox] Adjusts Master Audio or microphone volume for left
channel.
oo = 01 for Master Audio or 02 for microphone.
x = + (plus sign) to increment output volume.
x = – (minus sign) to decrement output volume.
x = @ to return output volume to factory default.
x = ? to request current volume level.
Set volume level—left
[VOLLooxxx] Sets Master Audio or microphone volume for left channel.
oo = 01 for Master Audio or 02 for microphone.
xxx = -550 to 090
090 equals maximum gain (+9dB), 000
equals factory default (unity gain), and
-550 equals minimum gain (-55dB).
