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 6. If after ringing out the system, you feel you need to squeeze a little more gain out of the

system before feedback, 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 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 AFS menu. “F” indicates Fixed filters and

“L” indicates Live filters. A highlighted F or L indicates a filter that is set, or in use.

• LIVE LIFT [ON, OFF]

This parameter turns the LIVE LIFT feature on and off. When turned on, this parameter essentially enables a timer. Turn

LIVE LIFT on when you want AFS to lift (release) 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).

• 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 remove a set Live filter. The selectable options range from 5S (5 seconds) to 60M (60 minutes). The updated AFS

algorithm in the PA2 will slowly release Live filters by 3 dB increments to determine if it is safe to remove them. If it gets to

0 dB and no feedback reoccurs, the filters are completely lifted. If feedback attempts to reappear while releasing, the filters

are 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 needs to remain set.

• SELECTED FILTER [1 - 12]

This parameter selects between the available filters shown at the bottom of the LCD display when in the AFS menu and

provides information on each filter. “L” represents a Live filter and “F” represents a Fixed filter. As you select each filter, the

set frequency, Q, and amount of attenuation will be shown for the filter in the bottom of the LCD display.
