Example:	EVM}	Mut023010000000]

Mute output X@ RGB (video off). Unmute output X@ RGB (video on).

1 = muted, 0 = not muted. Mute all RGB outputs. Unmute all RGB outputs.

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

1 = muted, 0 = not muted. Mute all audio outputs. Unmute all audio outputs.

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

Output 2 audio left is muted, output 3 video and both audio channels are muted, and output 5 video is 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 – 12 (video mutes) or 01 – 06 (audio mutes)
X$ = Mute	0 = not muted, 1 = muted
X%= Video/audio mute:	0	= no mutes	4	= audio right (AR) mute
	1	= video mute	5	= video and AR mute
	2	= audio left (AL) mute	6	= AL and AR mute
	3	= video and AL mute	7	= video, AL, and AR mute

Audio input gain and attenuation

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

Set input audio gain to +dB value	X!*X^G	InX!•AudX&]
Example:	1*2G	In01•Aud+02]	Set input 1 audio gain to +2 dB.
Set input audio attenuation to -dB	X!*X*g	InX!•AudX&]
value
Increment gain	X!+G	InX!•AudX&]	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!•AudX&]	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	X&]
N X! = Input number	01 – 14
X^ = Audio gain	0 – 24 (1 dB/step)
X& = Numeric dB value	–18 to +24 (45 steps of gain or attenuation) (Default = 0 dB)
X* = Audio attenuation	1 – 18 (1 dB/step)
