channels 1 and T (the telephone input) .

Using the wildcard character, '*', to specify the channel with this command is not supported for the EF2211. To set or query the command, the channels must be specified explicitly (e.g., 'S01AGC1?',

'S01AGCT0').

This command is a channel boolean command. See Section 6.3 and Section 6.1 for more information on this type of command.

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.

8.6.AGCMAX -- Set Maximum Allowed Mic/Line Input AGC

Gain

This command sets the maximum gain that the AGC can apply on input channels 1 and T (the telephone input) . For example, if AGCMAX is set to 10, then the AGC for that channel can apply a maximum of 10 dB of gain to the input signal.

Using the wildcard character, '*', to specify the channel with this command is not supported for the EF2211. To set or query the command, the channels must be specified explicitly (e.g.,

'S01AGCMAX1?', 'S01AGCMAXT7').

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.
