Operation Manual

This command is a boolean command. See Section 6.1 for more information on this type of command.
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 Status Message
F01ACKMOD1
Enable acknowledgement mode.
F01ACKMOD1
F01ACKMOD0
Disable acknowledgement mode.
F01ACKMOD0
F01ACKMOD2
Toggle acknowledgement mode.
F01ACKMODx , where x is 0 or 1 depending on the current
state of acknowledgement mode.
F01ACKMOD?
Query acknowledgement mode.
F01ACKMODx , where x is 0 or 1 depending on the current
state of acknowledgement mode.
8.2. AEC -- Enable or Disable Acoustic Echo Cancellation
This command sets or queries the status of the Acoustic Echo Cancellation (AEC) algorithm on input channels 1-8
.
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.
