Audio input gain and attenuation

NThe set gain (G) and set attenuation (g) commands are case sensitive.

Set input audio gain to +dB	X#*X1&G	InX#•AudX1*]
value
Example:	1*2G	In01•Aud+02]	Set input 1 audio gain to
			+2 dB.
Set input audio attenuation	X#*X1(g	InX#•AudX1*]
to -dB value
Increment gain	X#+G	InX#•AudX1*]	Increase gain by 1 dB.
Example:	5+G	In05•Aud+03]	Increase audio input 5 level
			from +2 dB to +3 dB.
Decrement gain	X#-G	InX#•AudX1*]	Decrease gain by 1 dB.
Example:	7-G	In07•Aud-09]	Decrease audio input 7 level
			from -8 dB to -9 dB.
Read input gain	X#G	X1*]
