Audio input gain and attenuation (HVA models)
The set gain (G) and set attenuation (g) commands are case sensitive.
Set audio input gain to + dB value X1 * X6 G In X1 •Aud X5
Example: 1*2G In01•Aud+02 Set input 1 audio gain to +2 dB.
Set audio input attenuation to - dB value X1 * X7 g In X1 •Aud X5
Increment gain X1 +G In X1 •Aud X5 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 X5 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 X5
Audio output volume (HVA models)
The table on page 4-9 defines the value of each audio volume step.
Set audio volume to specific value X3 * X8 V Out X4 •Vol X8
Example: 1*50v Out01•Vol50 Set output 1 volume to 79%.
Increment volume X3 +V Out X3 •Vol X8 Increase volume by 1 step.
Example: 1+V Out01•Vol51 Audio output 1 level
incremented from 79% to 80.5%.
Decrement volume X3 –V Out X3 •Vol X8 Decrease volume by 1 step.
Read output volume X3 V X8
Audio mute commands (HVA models)
Audio mute X3 *1Z Amt X3 *1 Mute output X3 audio (audio
off).
Audio unmute X3 *0Z Amt X3 *0 Unmute output X3 audio (audio
on).
Read audio mute X3 Z X4 1= mute on, 0 = mute off.
Global audio mute 1*Z Amt1
Global audio unmute 0*Z Amt0
Names
Write global preset name Esc X9 , X13 NG Nmg X9 , X13
Example: Esc 1,Security•1NG
Nmg01,Security•1 Name global preset 1 “Security 1”.
Read global preset name Esc X9 NG X13
Example: Esc 2NG Security•1
• If a preset is unassigned, then
X13
displays [unassigned].
• If a global preset is saved, but not yet named, the default name is Global•Pr# X9 .
