Audio input gain and attenuation

NOTE: The set gain (G) and set attenuation (g) commands are case sensitive.

Set input audio gain to +dB value

Example:

Set input audio attenuation to -dB value

Increment gain

Example:

Decrement gain

Example:

Read input gain

X#*X*G	InX#•AudX&]
1*2G	In01•Aud+02]	Set input 1 audio gain to +2 dB.
X#*X(g	InX#•AudX&]
X#+G	InX#•AudX&]	Increase gain by 1 dB.
5+G	In05•Aud+03]	Increase input 5 audio level from +2 dB to +3 dB.
X#-G	InX#•AudX&]	Decrease gain by 1 dB.
7-G	In07•Aud-09]	Decrease input 7 audio level from -8 dB to -9 dB.
X#G	X&]

Audio mute commands

Audio mute	X!*1Z	AmtX!*1]
Audio unmute	X!*0Z	AmtX!*0]
Read audio mute	X!Z	X%]
Global audio mute	1*Z	Amt1]
Global audio unmute	0*Z	Amt0]

Mute output X! audio (audio off). Unmute output X! audio (audio on). 1 = mute on, 0 = mute off.

Mute all audio outputs.

Unmute all audio outputs.

Save, recall, and directly write presets

NOTES: • If you try to recall a preset that is not saved, the matrix switcher responds with the error code E11.

• The following characters are invalid or not recommended or not recommended in preset names: + - , ` @ = [ ] { } ‘ “ ; : \ and ?.

Save current configuration	X1),	SprX1)]
as a global preset
Example:	9,	Spr9]
Recall a global preset	X1).	RprX1)]
Example:	5.	Rpr05]

Direct write process —

Command character is a comma.

Save current ties as preset 9. Command character is a period.

Recall preset 5, which becomes the current configuration.

NOTE: The direct write of a global preset should always be preceded by a clear global preset ties command of that same preset number,

as shown below. In a directly-written preset, the tied input of each output position (or no tied input) remains unchanged unless

overwritten or cleared.

If you do not clear the ties in a global preset number before you directly write a global preset to that number, ties that are part of the previous version of the specified preset with the same number can unexpectedly become part of the newly-created preset.

Clear ties of a global preset

Directly write a global preset

Example:

E+X1)P0*!} SprX1)]

E+X1)PX!*X@!X!*X@%X!*X@$ ... X!*X@%}

SprX1)]

E+27P0*!} Spr27]

E+27P2*5!10*2$13*11%3*6&

Spr27]

Clear all ties in preset X1).

Enter as many ties as are valid for this configuration. The ! tie all, & tie RGB, % tie video, and $ tie audio commands are all valid. Clear all ties in preset 27.

Brackets are shown to separate ties for clarity only. Create global preset 27, which ties input 2 video and audio to output 5, input 10 audio to output 2, input 13 video to output 11, and input 3 video to output 8.

NOTE: X! = Input number (for tie)	00		(untied)	01	– 08 for the computer group	09 – 14 for the low resolution group
X@ = Output number	01		– 12 for video	01	– 06 for audio
X# = Input number	11		– 14 (the only valid inputs for the / command)
X% = Mute status	0	= off		1 = on
X& = Numeric dB value	–18 to +24 (45 steps of gain or attenuation) (default = 0)
X* = Audio gain	0	– 24 (1 dB per step)
X( = Audio attenuation	1	– 18 (1 dB per step)
X1) = Global preset #	32 maximum
