Audio input gain and attenuation
	The set gain (G) and attenuation (g) commands are case sensitive.
Set audio input gain to +dB value		X1	*	X5	G	In		X1	•Aud	X4
Example:		1*2G				In01•Aud+02					Set input 1 audio level to +2 dB
											gain.
Set audio input attenuation to -dB value			*		g	In			•Aud
		X1		X6				X1		X4
Example:		3*5g				In03•Aud-05					Set input 3 audio level to -5 dB
											attenuation.
Increment gain		X1	+G			In		X1	•Aud	X4	Increase gain by 1 dB.
Example:		5+G				In05•Aud+03					Audio input 5 level incremented
											from +2 dB to +3 dB.
Decrement gain			-G			In			•Aud		Decrease gain by 1 dB.
		X1						X1		X4
Example:		7-G				In07•Aud-09					Audio input 7 level decremented
											from -8 dB to -9 dB.
Read input gain		X1	G				X4
Example:		2G				+11					Input 2 audio level is +11 dB
											gain.

Audio output volume

The adjustment range is between 0 and 100% audio output volume in 1 dB steps of attenuation. Each 1 dB equals approximately a 2% reduction in audio output volume.

Set audio volume to % of max. value

Example:

Odd-numbered

	X3	*	X7	V	Out	X3	•Vol	X7
1*50v					Out01•Vol50				Set output 1 volume to 50%.

X7 values are rounded up to even-numbered values.

Increase volume	X3	+V	Out	X3	•Vol	X7	Increase volume by 2%.
Example:	1+V		Out01•Vol52				Audio output 1 level
							incremented from 50% to 52%.
Decrease volume	X3	-V	Out	X3	•Vol	X7	Decrease volume by 2%.
Example:	1-V		Out01•Vol50				Audio output 1 level
							incremented from 52% to 50%.

Read output volume		X3
Example:	V

V X7

Vol50 Audio output 1 level is 50%.

Audio mute commands

Audio mute	X3	*1Z	Amt	X3	*1	Mute output	X3		audio (audio
						off).
Example:	3*1Z		Amt03			Mute output 3 audio.
Audio unmute		*0Z	Amt		*0	Unmute output				audio (audio
	X3			X3				X3
						on).
Read audio mute	X3	Z	X8			1= mute on, 0 = mute off.
Global audio mute	1*Z		Amt1			Mute all audio outputs. The
						front panel Mute All LED lights.
Global audio unmute	0*Z		Amt0			Unmute all audio outputs. The
						front panel Mute All LED goes
						out.
