17.2. Enabling the FBS Function
If acoustic feedback occurs when the FBS function is enabled, the feedback suppressor filter automatically
operates to suppress the feedback.
The FBS function set to each channel of the MONO INPUTs 1 – 8 operates independently.
Note
The function can also be set using the supplied M-864D PC Software.
For details, read the separate Software instructions.
Tips
• The feedback suppressor filter to which the guard setting is not assigned will be cleared when the unit is
powered on.
For the guard setting, read the separate Software instructions.
• Even if you switch the Preset memory number during operation, the feedback suppressor filter currently in
operation remains active and unchanged.
