Each X1% response is the mute status of an output, starting from output 1.

n = the maximum number of outputs for this model.

Output 2, 3, 5, 10, 11, and 13 audio or RS-232 are muted. All other outputs are unmuted.

Audio input gain and attenuation

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

Set input audio gain to +dB value	X!*X1^G	InX!•AudX1&]
Example:	1*2G	In01•Aud+02]	Set input 1 audio gain to +2 dB.
Set input audio attenuation to -dB	X!*X1*g	InX!•AudX1&]
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 level	X!G	X1&]
N X!= Input number	01 – (maximum number of inputs for your model)
X1^= Audio gain	0 – 24 (1 dB per step)
X1&= Numeric dB value	–18 to +24 (45 steps of gain or attenuation) (Default = 0 dB)
X1*= Audio attenuation	1 – 18 (1 dB per step)
