The Autolearn function on my Behringer FBQ2496 Feedback Destroyer is not working properly.

The first time you power on your Feedback Destroyer, all 20 of the available filter slots may be already assigned to the parametric equalizer. In order for the Autolearn function to work, you’ll need to free up some or all of the filter slots so they can be assigned to the Learn function. To do this, follow the steps below:

1. When you power on the Feedback Destroyer, the display will briefly show the firmware version (ex: 1.1) and then it will show “run.” This indicates the unit is ready to be used.
2. Press and hold the PEQ button until you see the letter “P” followed by a number. The number represents how many filter slots are assigned to the parametric equalizer.
3. To reduce the number of filter slots assigned to the PEQ, turn the jog wheel counter-clockwise. You will see the Channel 1/L and Channel 2/R LEDs go out as you remove filter slots from the PEQ.
4. Press the PEQ button to exit this setting.
5. Next, tap the LEARN button. The display will show “S” followed by a number. This number represents the how many filter slots are assigned to the Learn function.
6. Turn the jog wheel clockwise to add filter slots to the Learn function.
7. Tap the LEARN button to exit this setting.
8. Now, when you run the Autolearn sequence (by holding the LEARN button) you will see the slots you have assigned to the Learn function illuminate as the troublesome frequencies are detected.
