8.49. GAINGIM -- Set Gain of Microphone Inputs as a Group
This command sets the gains of all the microphone inputs simultaneously. This is different from using a wildcard,
* with the
GAINI command because that command sets all the mic and line inputs together, while the GAINGIM
sets only the mic inputs.
This command will generate acknowledgements from each of the mic inputs separately.
This command is an integer command. See
Section 6.2 for more information on this type of command. The
minimum and maximum values for this command are 0 and 30, respectively.
This command is saved to non-volatile memory only as part of a preset. The state of this command will be
restored after power-up only if a preset is saved and that preset is set to be the power-on preset.
