8.2. ACKMOD -- Enable or Disable Acknowledgment Mode

This command controls whether or not status messages are sent. See
status messages. This parameter is enabled by default, and it is rarely turned off by the host controller.
This command is a boolean command. See
This command is saved to global non-volatile memory and is not part of a preset. Its value is saved each
time it is changed. It will retain its value after power-down. Since this command writes to non-volatile
memory, there will be a delay before an acknowledgment is returned.
Example Description
B01ACKMOD1 Enable acknowledgement mode. B01ACKMOD1
B01ACKMOD0 Disable acknowledgement mode. B01ACKMOD0
B01ACKMOD2 Toggle acknowledgement mode.
B01ACKMOD? Query acknowledgement mode.

8.3. AEC -- Enable or Disable Acoustic Echo Cancellation

This command sets or queries the status of the Acoustic Echo Cancellation (AEC) algorithm on input channels
1-4 .
This command is a channel boolean command. See
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.
Example Description
B01AEC31 Enable AEC on input channel 3 .
B01AEC30 Disable AEC on input channel 3 .
B01AEC32 Toggle AEC state on input channel 3 .
B01AEC3? Query AEC state on input channel 3 .
B01AEC*1 Enable AEC on input channels 1-4.
B01AEC*0 Disable AEC on input channels 1-4.
B01AEC*2 Toggle AEC state on input channels 1-4.
