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 Read video output tie Read audio output tie

X@&	X!]
X@%	X!]
X@$	X!]

RGB input X! is tied to output X@. Video input X! is tied to output X@. Audio input X! is tied to output X@.

Video mutes

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

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

X# = 1 = enable (muted)

0 = disable (unmuted) (default). Mute all video outputs.

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$*X%G
Example:	1*2G
Set audio input attenuation to -dB	X$*X&g
value
Increment gain	X$+G
Example:	5+G
Decrement gain	X$-G
Example:	7-G
Read input gain	X$G
Example:	3G

Set input 1 audio gain to +2 dB.

Increase gain by 1 dB.

Increase audio input 5 level from +2 dB to +3 dB.

Decrease gain by 1 dB.

Decrease audio input 7 level from -8 dB to -9 dB.

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	–18to +24 (45 steps of gain or attenuation) (Default = 0 dB)
X& = Audio attenuation	1	– 18 (1 dB per step)
