Video and audio mute commands
RGB/video mute X@ *1B Vmt X@ *1 ] Mute output X@ RGB (video off).
RGB/video unmute X@ *0B Vmt X@ *0 ] Unmute output X@ RGB (video on).
Read RGB/video mute X@ B X$] 1 = muted, 0 = not muted.
Global RGB/video mute 1*B Vmt1 ] Mute all RGB outputs.
Global RGB/video unmute 0*B Vmt0 ] Unmute all RGB outputs.
Audio mute X@ *1Z Amt X@ *1 ] Mute output X@ audio (audio off).
Audio unmute X@ *0Z Amt X@ *0 ] Unmute output X@ audio (audio on).
Read audio mute X@ Z X$] 1 = muted, 0 = not muted.
Global audio mute 1*Z Amt1 ] Mute all audio outputs.
Global audio unmute 0*Z Amt0 ] Unmute all audio outputs.
View output mutes E VM } X% 1 , X% 2 , ... X% 12 ] Each X% response is the mute status of an
output, starting from output 1.
Example: E VM } Mut023010000000 ] 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.
N The “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
N The set gain (G) and set attenuation (g) commands are case sensitive.
Set input audio gain to +dB value X! * X^ G In X! •Aud X&]
Example: 1*2G In01•Aud+02 ] Set input 1 audio gain to +2 dB.
Set input audio attenuation to -dB
value X! * X* g In X! •Aud X&]
Increment gain X! +G In X! •Aud X&] 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 In X! •Aud X&] 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)
