8.70.LAGCMAX -- Set Maximum Allowed Line Input AGC

Gain

This command sets the maximum gain that the AGC can apply on input channels A-B. For example, if LAGCMAX is set to 10, then the AGC for that channel can apply a maximum of 10 dB of gain to the input signal.

This command was introduced in firmware version 2.5.0.

This command is a channel integer command. See Section 6.3 and Section 6.2 for more information

on this type of command. The minimum and maximum values for this command are 0 and 15, 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.
