B01AEC*?
Query AEC state on input channels 1-4.
B01AEC*abcd, where a-d are each 0 or 1 depending
on the current state of the AEC for each of the four
input channels.
8.4. AECMODE -- Set Amount of Double Talk Suppression used
in the AEC.
This command sets the amount of double talk suppression used in the AEC on input channels 1-4 . The
values correspond to the following settings.
● 1 = No Suppression
● 2 = Light Suppression
● 3 = Heavy Suppression
● 4 = Half Duplex
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 1 and 4, 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.
Example Description Status Message
B01AECMODE13
Set AEC on input channel 1 to
Heavy Suppression.
B01AECMODE13
B01AECMODE1?
Query AEC suppression level on
input channel 1.
B01AECMODE1x , where x is 1, 2, 3, or 4
depending on the current setting of the AEC
suppression level on input channel 1.
B01AECMODE*1
Set AEC on input channels 1-4
to No Suppression.
B01AECMODE*àààà
B01AECMODE*ààêê
Set AEC on input channels 1-2
to No Suppression and AEC on
input channels 3-4 to Half
Duplex.
B01AECMODE*ààêê
B01AECMODE*?
Query AEC suppression level on
input channels 1-4.
B01AECMODE*abcd, where a-d are each à, å, ç, or
ê depending on the the current setting of the AEC
suppression levels on input channels 1-4.
8.5. AGC -- Enable or Disable Mic/Line Input Automatic Gain
Control
This command sets or queries the status of the Automatic Gain Control (AGC) algorithm on input channels 1-
4 and T (the telephone input) .
When the wildcard character, '*', is used to specify the channel in this command, it only affects input
channels 1-4. To set or query the telephone input channel, T, you must specify it explicitly (e.g.,
'B01AGCT1', 'B01AGCT?').
