Feedback suppression function operations
[Suppressing acoustic feedback with a simple operation]
Step 1. Set the volume controls of connected external equipment to the state in which they will actually be
used. Establish connection between the unit and a PC for communication.
Step 2. Click the Auto start button in the FBS view to activate the Auto mode.
All filters (12 bands) that suppress feedback are set after they are initialized.
Notes
• Auto mode cannot be initiated if the number of Auto mode filters is set to 0.
• Large sounds are produced during Auto mode operation.
• During auto mode operation, the dynamic mode in all the FBS boxes for that unit remains
suspended.
• Setting takes about 1.5 minutes. (This may differ depending on the unit installation circumstances.)
• No keys can be used during Auto mode operation. Click the Auto start button again to interrupt
setup operations.
[Settings to be performed as required]
Step 3. Set the Dynamic mode or the number of filters in the FBS view as required.
Notes
• When the number of filters to be used for the Auto and Dynamic modes have been changed,
reactivate the Auto mode.
• Take care when executing filter initialization, as feedback may occur.
• It is recommended that the Auto mode be reset when the equalizer setting value has been changed,
because the feedback points may change.
