Audio input gain and attenuation
The set gain (G) and attenuation (g) commands are case sensitive.
Set audio input gain to +dB value X1 * X5 G In X1 •Aud X4
Example: 1*2G In01•Aud+02 Set input 1 audio level to +2 dB
gain.
Set audio input attenuation to -dB value X1 * X6 g In X1 •Aud X4
Example: 3*5g In03•Aud-05 Set input 3 audio level to -5 dB
attenuation.
Increment gain X1 +G In X1 •Aud X4 Increase gain by 1 dB.
Example: 5+G In05•Aud+03 Audio input 5 level incremented
from +2 dB to +3 dB.
Decrement gain X1 -G In X1 •Aud X4 Decrease gain by 1 dB.
Example: 7-G In07•Aud-09 Audio input 7 level decremented
from -8 dB to -9 dB.
Read input gain X1 G X4
Example: 2G +11 Input 2 audio level is +11 dB
gain.
Audio output volume
The adjustment range is between 0 and 100% audio output volume in 1 dB steps of attenuation.
Each 1 dB equals approximately a 2% reduction in audio output volume.
Set audio volume to % of max. value X3 * X7 V Out X3 •Vol X7
Example: 1*50v Out01•Vol50 Set output 1 volume to 50%.
Odd-numbered
X7
values are rounded up to even-numbered values.
Increase volume X3 +V Out X3 •Vol X7 Increase volume by 2%.
Example: 1+V Out01•Vol52 Audio output 1 level
incremented from 50% to 52%.
Decrease volume X3 -V Out X3 •Vol X7 Decrease volume by 2%.
Example: 1-V Out01•Vol50 Audio output 1 level
incremented from 52% to 50%.
Read output volume X3 V X7
Example: V Vol50 Audio output 1 level is 50%.
Audio mute commands
Audio mute X3 *1Z Amt X3 *1 Mute output X3 audio (audio
off).
Example: 3*1Z Amt03 Mute output 3 audio.
Audio unmute X3 *0Z Amt X3 *0 Unmute output X3 audio (audio
on).
Read audio mute X3 Z X8 1= mute on, 0 = mute off.
Global audio mute 1*Z Amt1 Mute all audio outputs. The
front panel Mute All LED lights.
Global audio unmute 0*Z Amt0 Unmute all audio outputs. The
front panel Mute All LED goes
out.
