Read ties
NOTE: The & read tie command for RGB and the % read tie command for video can be used interchangeably on the matrix switchers.
Read RGB (video) output tie X@ & X!] RGB input X! is tied to output X@ .
Read video output tie X@ % X!] Video input X! is tied to output X@ .
Read audio output tie X@ $ X!] Audio input X! is tied to output X@ .
Video mutes
RGB or video mute X@ *1B Vmt X@ *1 ] Mute output X@ video (video off).
RGB or video unmute X@ *0B Vmt X@ *0 ] Unmute output X@ video (video on).
Read RGB or video mute X@ B X#] X# = 1 = enable (muted)
0 = disable (unmuted) ( default).
Global RGB or video mute 1*B Vmt1 ] Mute all video outputs.
Global RGB or video unmute 0*B Vmt0 ] Unmute all video outputs.
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 In01•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 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 gain X$ G X^]
Example: 3G -06 ] Audio input 3 level is at -6 dB.
NOTE: X! = Input number (for tie) 00 – (maximum number of inputs for your model) (00 = untied)
X@ = Output number 01 – (maximum number of outputs for your model)
X# = Mute status 0 = off (unmuted) 1 = on (muted)
X$ = Input number (for other than tie) 01 – (maximum number of inputs for your model)
X% = Audio gain 0 – 24 (1 dB per step)
X^ = Numeric dB value –18 to +24 (45 steps of gain or attenuation) (Default = 0 dB)
X& = Audio attenuation 1 – 18 (1 dB per step)
