17. FBS FUNCTION SETTINGS

17.1. What is the Feedback Suppressor Function (FBS)?

FBS stands for Feed-Back Suppressor.

The feedback suppressor filter automatically operates to 

suppress acoustic feedback when the feedback occurs.

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.

 Step 1. Press the FBS switch when the Feedback suppressor indicator remains unlit.

Note

Use a fine-tipped object to press 

in the FBS switch.

Note

Feedback may not be suppressed as the case may be. In this case, decrease the input level by moving 

down the input fader of the corresponding channel.

 Step 2. Release the FBS switch when the Feedback suppressor indicator lights.

When the Feedback suppressor indicator lights, the FBS function is enabled.
