Audio or RS-232 mute commands
Audio or RS-232 mute X@ *1Z Amt X@ *1 ] Mute output X@ audio (audio off).
Audio or RS-232 unmute X@ *0Z Amt X@ *0 ] Unmute output X@ audio (audio on).
Read audio or RS-232 mute X@ Z X*] 1 = mute on, 0 = mute off.
Global audio or RS-232 mute 1*Z Amt1 ] Mute all audio outputs.
Global audio or RS-232 unmute 0*Z Amt0 ] Unmute all audio outputs.
View output mutes E VM } X( 1 , X( 2 , ... X( n ] Each X( response is the mute status of an
output, starting from output 1.
n
= the maximum number of outputs for this
model.
Example: MTPX 3216 E VM } Mut0220200002202000 ] Output 2, 3, 5, 10, 11, and 13 audio or RS-232
are muted. All other outputs are unmuted.
N The “Mut” portion of the response appears only when the switcher is in Verbose mode 3. See the Verbose mode command on page 4-10.

Audio input gain and attenuation
N The set gain (G) and set attenuation (g) commands are case sensitive.
Set input audio level to +dB value X! * X1) G In X! •Aud X1!]
Example: 1*2G In01•Aud+02 ] Set input 1 audio gain to +2 dB.
Set input audio level to -dB value X! * X1@ g In X! •Aud X1!]
Increment gain X! +G In X! •Aud X1!] 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 In X! •Aud X1!] 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!]
Audio output volume
Set the audio volume to a specific
value X@ * X1# V Out X@ •Vol X1#]
Example: 1*50v Out01•Vol50 ] Set output 1 volume to 79%.
Increment volume X@ +V Out X@ •Vol X1#] Increase volume by 1 step.
Example: 1+V Out01•Vol51 ]
Decrement volume X@ -V Out X@ •Vol X1#] Decrease volume by 1 step.
Read output volume X@ V X1#]
N
X@
= Output number 01 – (maximum number of outputs for your model)
X*
= Mute 0 = off (unmuted)
1 = on (muted)
X( = Audio or RS-232 mute: 0 = no mutes
2 = audio or RS-232 mute
N
X! = Input number 01 – (maximum number of inputs for your model)
X1) = Audio gain 0 – 24 (1 dB/step)
X1! = Numeric dB value –18 to +24 (45 steps of gain or attenuation) (Default = 0 dB)
X1@
= Audio attenuation 1 – 18 (1 dB/step)
X@
= Output number 01 – (maximum number of inputs for your model)
X1# = Volume adjustment range 0 – 64 (1 dB/step except for 0-to-1, which is 22 dB) (default = 64 [0 dB])
