Mute output X@ audio (audio off). Unmute output X@ audio (audio on).

1 = mute on, 0 = mute off. Mute all audio outputs. Unmute all audio outputs.

Each X( response is the mute status of an output, starting from output 1.

n = the maximum number of outputs for this model.

Output 2, 3, 5, 10, 11, and 13 audio or RS-232 are muted. All other outputs are unmuted.

NThe “Mut” portion of the response appears only when the switcher is in Verbose mode 3. See the Verbose mode command on page 4-10.

N X@= Output number	01 – (maximum number of outputs for your model)
X*= Mute	0	= off (unmuted)
X(= Audio or RS-232 mute:	1	= on (muted)
	0	= no mutes
	2	= audio or RS-232 mute

Audio input gain and attenuation

NThe set gain (G) and set attenuation (g) commands are case sensitive.

Set input audio level to +dB value	X!*X1)G	InX!•AudX1!]
Example:	1*2G	In01•Aud+02]	Set input 1 audio gain to +2 dB.
Set input audio level to -dB value	X!*X1@g	InX!•AudX1!]
Increment gain	X!+G	InX!•AudX1!]	Increase gain by 1 dB.
Example:	5+G	In05•Aud+03]	Increase audio input 5 level from +2 dB to +3 dB.
Decrement gain	X!-G	InX!•AudX1!]	Decrease gain by 1 dB.
Example:	7-G	In07•Aud-09]	Decrease audio input 7 level from -8 dB to -9 dB.
Read input level	X!G	X1!]
Audio output volume
Set the audio volume to a specific	X@*X1#V	OutX@•VolX1#]
value
Example:	1*50v	Out01•Vol50]	Set output 1 volume to 79%.
Increment volume	X@+V	OutX@•VolX1#]	Increase volume by 1 step.
Example:	1+V	Out01•Vol51]
Decrement volume	X@-V	OutX@•VolX1#]	Decrease volume by 1 step.
Read output volume	X@V	X1#]

N X!= Input number		01 – (maximum number of inputs for your model)
