			digital over analog audio.
View input audio selection	EIAFMT}	AfmtIX&]	View the input audio format setting.

Audio gain and attenuation

NOTE: Audio gain (G) and attenuation (g) are case sensitive.

Set audio gain	X1@G	AudX1@]	Sets audio gain on current input to X1@.
Set audio attenuation	X1#g	AudX1#]	Sets audio attenuation on current input
			to X1#.
Increase gain	+G	AudX1$]	Increments audio level.
Decrease gain	-G	AudX1$]	Decrements audio level.
View gain	G	AudX1$]	View the audio level of the current input.
Loop-through audio mute
Mute loop-through audio	1Z	Amt1]	Mute the embedded audio.
Unmute the loop-through audio	0Z	Amt0]	Unmute the embedded audio.

Black signal for audio only

NOTE: The transmitter uses a black signal to simulate a 720p or 1080p, 50 Hz or 60 Hz signal so audio can be passed without video.

Set black signal resolution	EAX2)AFMT}	AfmtAX2)]		Set the black signal resolution.
View black signal resolution	EAAFMT}	AfmtAX2)]		View the current black signal resolution.
Enable black signal	EB1AFMT}	AfmtB1]		Enable the black signal for audio only.

X1@ = Audio gain		0 - 24 = decibels above 0
X1# = Audio attenuation		–18- 0 = decibels below 0
X1$ = Audio level		–18- +24 (0 dB = default)
X1% = Audio mute		0 = unmute all
		1	= mute loop-through audio
X2) = Black signal resolution		2 = 1280 x 720p, 50 Hz
