Video mute commands

Video mute	X@*1B	VmtX@*1]
Video unmute	X@*0B	VmtX@*0]
Read video mute	X@B	X#]
Global video mute	1*B	Vmt1]
Global video unmute	0*B	Vmt0]

Mute output X@ RGB (video off).

Unmute output X@ RGB video on).

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

Audio input gain and attenuation

NThe set gain (G) and set attenuation (g) commands are case sensitive. The increment and view commands are not case sensitive.

NYou can set the input level to whole dB values only, using the X$*X%G or X$*X&g command. The increment and decrement level (X$+G and X$-G) commands increase and decrease the level in steps of 0.5 dB only. The X^ values for all audio gain and attenuation commands are reported in whole dB levels only; the reported X^ value is rounded up to the next higher magnitude value (for example, +1.5 dB is reported as +2 dB and -3.5 dB is reported as -4 dB).

Set input audio gain to +dB	X$*X%G	InX$•AudX^]
value
Example:	1*2G	In01•Aud+02]	Set input 1 audio gain to
			+2 dB.
Set input audio attenuation	X$*X&g	InX$•AudX^]
to -dB value
Increment gain	X$+G	InX$•AudX^]	Increase audio level by 0.5 dB.
Example:	5+G	In05•Aud+03]	Increment audio input 5
			level from +2 dB to +2.5 dB.
Decrement gain	X$-G	InX$•AudX^]	Decrease audio level by 0.5 dB.
Example:	7-G	In07•Aud-09]	Decrement audio input 7
			level from -08 dB to -8.5 dB.
View input gain	X$G	X^]
N X@ = Output number		01 – (maximum number of outputs for your model)
X# = Mute status		0 = off, 1 = on
X$ = Input number		01 – (maximum number of inputs for your model)
X% = Audio gain		0 – 24 (1 dB/step)
X^ = Numeric dB value		–18 to +24 (45 steps of gain or attenuation)
X& = Audio attenuation		1 – 18 (1 dB/step)
