Mic talk-over threshold

Display talk-over threshold

X8 *2 # Thr X8 Shows the mic threshold X

number. X8 = 0 through 15, default = 8.

Decrement threshold	-*2#	Thr	X8	Decremenst mic threshold one
				step.
Increment threshold	+*2#	Thr	X8	Increments mic threshold one

2 = talk-over threshold

X8 = Value range: 0 - 15 (8 = midrange = default)

Adjust audio ducking level

X12	*58#	Adl	X12	Adjusts how much
				(		= 0 to 30 dB) the program
					X12

audio ducks (automatically decreases) while the MPS is in talk over mode.

0 = audio ducking is off.

Increment audio ducking	+*58#	Adl	X12
Decrement audio ducking	-*58#	Adl	X12
View audio ducking level	58#	Adl
			X12

Program audio breakaway*

Switch program audio

X1 * X2 $ Pra X1 * X2 Selects any input from any X

group to be routed to the program audio output.

X1 = group 1 through 3 (1 = VGA, 2 = S-video, 3 = composite video).

X2 = inputs 0 through 4 for each group (input 0 = off).

This command works only in Separate mode with Follow sub-mode turned off. If Follow sub-mode is turned on or if the switcher is in Single Switcher mode, the program audio breakaway command does not work, and the response is an E10 error code.

*These groups of commands are new for units using firmware version 1.10 or higher. Earlier firmware versions do not support these four command groups.
