RGB mute commands
RGB mute X@ *1B Vmt X@ *1 ] Mute output X@ RGB (video off).
RGB unmute X@ *0B Vmt X@ *0 ] Unmute output X@ RGB (video on).
Read RGB mute X@ B X#] 1 = mute on, 0 = mute off.
Global RGB mute 1*B Vmt1 ] Mute all RGB outputs.
Global RGB unmute 0*B Vmt0 ] Unmute all RGB outputs.
IR 501 mute command responses
NOTE :
An IR 501 user can mute video, audio, or both with a string of IR commands that cannot be duplicated by a computer or control
system sending SIS commands. The switcher sends the following responses shown in the entries below.
IR 501 RGB and audio mute {none} Mut X@ *1 ] The RGB and audio from output X@ are
muted.
IR 501 RGB mute {none} Vmt X@ *1 ] The RGB from X@ output is muted.
IR 501 RGB and audio unmute {none} Zpz ] The RGB and audio from output X@ are
unmuted.
Audio input gain and attenuation
NOTE :
The set gain (G) and set attenuation (g) commands are case sensitive.
Set audio input gain to +dB value X$ * X% G In X$ •Aud X^]
Example: 1*2G In1•Aud+02 ] Set input 1 audio gain to +2 dB.
Set audio input 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 In5•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 In7•Aud-09 ] Decrease audio input 7 level from -8 dB
to -9 dB.
Read input gain X$ G X^]
Example: 3G -06 ] Audio input 3 level is at -6 dB.
Audio output level
Set audio output to the consumer
level (-10 dBV) X@ *0*40# Out X@ •Lvl0 ] Set output X@ level to consumer (-10
dBV).
Set audio output to the professional
level (+4 dBu) X@ *1*40# Out X@ •Lvl1 ] Set output X@ level to pro (+4 dBu)
(default).
Read output level X@ +40# X*]
Example: 3*40# 1 ] Output 3 audio level is pro (+4 dBu).
Audio mute commands
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 = mute on, 0 = mute off.
Global audio mute 1*Z Amt1 ] Mute all audio outputs.
Global audio unmute 0*Z Amt0 ] Unmute all audio outputs.
NOTE: X@ = Output number 1 through 4 (MVX 44, MVX 84) or 1 through 8 (MVX 48, MVX 88)
X# = Mute status 1 = on 0 = off
X$ = Input number 1 through 4 (MVX 44, MVX 48) or 1 through 8 (MVX 84, MVX 88)
X% = Input audio gain 0 through 10 (1 dB per step)
X^ = Numeric dB value –18 to +10 (29 steps [dB] of audio attenuation and gain)
X& = Input audio attenuation 1 through 18 (1 dB per step)
X* = Output gain 0 = consumer level (–10 dBV) 1 = pro level (+4 dBu)
