Example:	F			Frz0			Freeze mode is off.
Zoom
Zoom in	+{			Zom			Zoom in on the video image.
Zoom out	–{			Zom			Zoom out from the video image.

Audio gain and attenuation

The SIS commands for setting audio gain and attenuation are case sensitive. “G” sets gain and “g” sets attenuation. Increment, decrement, and view are not case sensitive.

Set gain

X12 G Aud

X14	Set gain for the selected input to
			dB.
		X12

Example:	3G	Aud+03	Set gain for the selected input to
			3 dB.

Set attenuation

X13

gAud

X14	Set attenuation for the selected
	input to		dB.
		X13

Example:	15g	Aud-15	Set attenuation for the selected
			input to -15 dB.

Increment level +G Aud

X14	Increase the selected input’s
	audio level by +1 dB.

Decrement level -G Aud

X14	Decrease the selected input’s
	audio level by -1 dB.

View audio level	G	Aud	X14	View gain for the selected input.
Example	G	Aud-03		The IN1508 reports that the
				audio level for the selected input
				is at -3 dB of attenuation.

Audio output volume

Set the output volume

X15 V Vol

X15	Set the volume for the audio
	output.

Increment the output volume +V Vol

X15	Increase the output’s volume
	level by 1 step.

Decrement the output volume -V Vol

X15	Decrease the output’s volume
	level by 1 step.

View the output volume V Vol

X15 Show the volume level.

Audio delay

Set the audio delay on	1@	Ad1		Delay audio to match the delay
				inherent in video scaling.
Set the audio delay off	0@	Ad0
View the audio delay	@	Ad
			X4
Example:	@	Ad1		Audio delay is on.
