FIXED FILTERS [0 - 24]
This parameter sets how many of the AFS filters will be allocated as Fixed filters. There are a total of 24 AFS filters available.
The number of Live filters is the difference between the total number of filters and the number of Fixed filters. For example, if
you select a FIXED FILTER setting of 12, you will have 12 Live filters available for use (24 - 12 = 12).
HINT:
Since it's not really possible to predict exactly how many Fixed filters you may need, a good setting to start with is
the default setting of 12. If you feel you need to squeeze more gain out of the system after the ring-out procedure, you can
increase the FIXED FILTERS setting and run the AFS Wizard again or manually ring out only the newly added Fixed filters
in the AFS OPTIONS menu.
NOTE:
If the FIXED FILTERS setting is changed after filters have been set, the filters will be cleared one by one as you
increase or decrease the setting. For example, if you decrease the FIXED FILTERS setting by one, the last Fixed filter set
will be cleared because the Fixed filter will be changed to a Live filter. Likewise, if the FIXED FILTERS setting is increased
by one (and thus the number of Live filters goes down), then the first Live filter set will be cleared. The Fixed/Live filter
allocation is indicated at the bottom of the LCD display in the Home Screen or in the AFS OPTIONS menu. 'F' indicates
Fixed filters and 'L' indicates Live filters. A highlighted F or L indicates a filter that is set, or in use.
CLEAR MODE [ALL, LIVE ONLY]
This parameter lets you select whether you would like to clear all filters (Live and Fixed) or only the Live filters.
CLEAR <PRESS SELECT>
Selecting this option then pressing the
selected for the CLEAR MODE parameter. See 'Clearing Filters' on page 17 for more information on clearing filters.
LIVE LIFT [ON, OFF]
This parameter turns the LIVE LIFT feature on and off. When turned on, this parameter enables a timer for each Live filter.
Turn LIVE LIFT on when you want AFS to lift Live filters after a predetermined time set by the LIFT AFTER parameter. Higher
fidelity can be restored to the system by lifting Live filters when they are no longer needed (for example, if a singer steps to
the front of the stage and triggers feedback, setting a Live filter, and then backs off).
If LIVE LIFT is off, the Live filters will remain in place until they are cleared by the user, the unit is power cycled, or a different
preset is loaded.
LIFT AFTER [5S - 60M]
When the LIVE LIFT parameter is turned on, this parameter determines how long it will take before AFS will attempt to lift
a set Live filter. The selectable options range from 5S (5 seconds) to 60M (60 minutes). Once a timer has expired, AFS will
slowly release the Live filter by 3 dB increments to determine if it is safe to remove it. If it gets to 0 dB and no feedback
reoccurs, the filters are completely lifted. If feedback attempts to reappear while releasing, the filter is once again set and the
timer resets. This helps prevent a sudden reoccurrence of blaring feedback in the event a Live filter is still needed and should
remain set.
wheel will clear set filters. Which filters will be cleared is determined by the option
