8.57. GAINGIL -- Set Gain of Line Inputs as a Group
This command sets the gains of all the line 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 GAINGIL sets only the line inputs.
This command will generate acknowledgements from each of the line 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 20, respectively.
