Audio input gain and attenuation

N• The set gain (G) and attenuation (g) commands are case sensitive. The increment, decrement, and read level commands are not case sensitive.

•Individual controls, offering finer trim adjustments (in 0.1 dB increments) for the right and left channels and group master offsets are present in the DSP and available through software control (see “DSP Configurator Program”, in chapter 5, “Switcher Software“). The results of these controls are not shown in the responses below.

Set input audio gain to	X#*X&G	InX#•AudX*]
+ dB value
Example:	1*2G	In01•Aud+02]	Set input 1 audio gain to
			+2 dB.
Set input audio attenuation	X#*X(g	InX#•AudX*]
to - dB value
Increment level	X#+G	InX#•AudX*]	Increase audio level by 1 dB.
Example:	6+G	In06•Aud+03]	Increment audio input 6
			level from +2 dB to +3 dB.
Decrement level	X#-G	InX#•AudX*]	Decrease audio level by 1 dB.
Example:	7-G	In07•-09]	Decrement audio input 7
			level from -08 dB to -9 dB.
Read input audio level	X#G	X*]
Audio mute
Audio mute	X@*1Z	AmtX@*1]	Mute audio output X@
			(audio off).
Audio unmute	X@*0Z	AmtX@*0]	Unmute audio output X@
			(audio on).
Read audio mute	X@Z	X%]	1 = mute on, 0 = mute off.
Global audio mute	1*Z	Amt1]	Mute all audio outputs.
Global audio ummute	0*Z	Amt0]	Unmute all audio outputs.
N X@ = Output number		01 – 06 for audio
X# = Input number		01 – 14
X% = Mute		0 = off (unmuted)
X& = Audio gain		1 = on (muted)
		0 – 24 (1 dB/step)
X* = Numeric dB value		–18 to +24 (45 steps of gain or attenuation) (Default = 0 dB)
X( = Audio attenuation		1 – 18 (1 dB/step
