Gain Mode
When the Imagestore 750 Configurator is in ‘Gain Mode’, you can define gain presets which can
then dynamically adjust overall gain and the level, trim, mute, and phase characteristics of indi-
vidual audio channels at various points within the audio mix.
To enter ‘Gain Mode’, select it from the drop-down list at the top right corner of the Imagestore
750 Configurator.
You can then create or edit gain preset files by selecting ‘File > New’ or ‘File > Open’. When you
create a gain preset file, you must specify the number of channels.
The following attributes may be defined for each gain preset file:
•
Number of channels
1 to 48
•
Master gain
+28 dB to –100 dB
0 dB default
•

•
Per-channel trim

•
