IR Video mute commands

An IR 501 user can mute video and/or audio 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:

IR 501 video and audio mute {none} Mut

X3	*1	Output
		muted.

X3 ’s video and audio are

IR 501 video mute	{none}	Vmt
IR 501 video and audio unmute	{none}	Zpz

X3 *1 Output X3 ’s video is muted.

Output X3 ’s video and audio are unmuted.

Audio input gain and attenuation

Set audio input gain to +dB value	X1	*	X5	G	In		X1	•Aud	X4
Example:	1*2G				In1•Aud+02					Set input 1 audio gain to +2 dB.
Set audio input attenuation to -dB value		*		g	In			•Aud
	X1		X6				X1		X4
Increment gain up	X1	+G			In		X1	•Aud	X4
Example:	5+G				In5•Aud+03					Audio input 5 level incremented
										from +2 dB to +3 dB.
Decrement gain down		-G			In			•Aud
	X1						X1		X4
Example:	7-G				In7•Aud-09					Audio input 7 level decremented
										from -8 dB to -9 dB.
Read input gain	X1	G				X4
Example:	3G				-06					Audio input 3 level is -6 dB.

Audio output level

Set audio output to consumer level (-10 dBV, default for RCA models)

Set audio output level to pro level (+4 dBu, default for captive screw models)

X3	*0*40#	Out	X3	•Lvl0	Set output	X3	level to the
					consumer level (-10 dBV).
	*1*40#	Out		•Lvl1	Set output		level to the pro

					level (+4 dBu).

Read output level		X3	*40#		X9
Example:	3*40#			1		Output 3 audio level is pro level
						(+4 dBu).
