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 X# * X* G In X# •Aud X&]
Example: 1*2G In01•Aud+02 ] Set input 1 audio gain to +2 dB.
Set input audio attenuation
to -dB value X# * X( g In X# •Aud X&]
Increment gain X# +G In X# •Aud X&] Increase gain by 1 dB.
Example: 5+G In05•Aud+03 ] Increase input 5 audio level from +2 dB to +3 dB.
Decrement gain X# -G In X# •Aud X&] Decrease gain by 1 dB.
Example: 7-G In07•Aud-09 ] Decrease input 7 audio level from -8 dB to -9 dB.
Read input gain X# G X&]
Audio mute commands
Audio mute X! *1Z Amt X! *1 ] Mute output X! audio (audio off).
Audio unmute X! *0Z Amt X! *0 ] Unmute output X! audio (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 unmute 0*Z Amt0 ] 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
as a global preset X1) , Spr X1)] Command character is a comma.
Example: 9, Spr9 ] Save current ties as preset 9.
Recall a global preset X1) . Rpr X1)] Command character is a period.
Example: 5. Rpr05 ] Recall preset 5, which becomes the current
configuration.
Direct write process —
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 E + X1) P0*! } Spr X1)] Clear all ties in preset X1) .
Directly write a global
preset E + X1) P X! * X@ ! X! * X@ % X! * X@ $ ... X! * X@ % } Enter as many ties as are valid for this
configuration. The ! tie all, & tie RGB, % tie
video, and $ tie audio commands are all valid.
Spr X1)]
Example: E +27P0*! } Spr27 ] Clear all ties in preset 27.
E +27P2*5!10*2$13*11%3*6&
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.
Spr27 ]
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
