USING THE FEEDBACK FILTER
The FEEDBACK FILTER control lets you reduce or eliminate squeal and other noise caused by
feedback.
After you adjust MASTER VOLUME , MIC 1 , MIC 2 , MIC 3 , MIC 4/PHONO , and CD/AUX , turn on the
amplifier and any connected sound source. If you hear any feedback, turn FEEDBACK FILTER
clockwise until you reduce or eliminate the feedback.
Note: The FEEDBACK FILTER control decreases feedback frequencies by up to 12 dB. If it does
not eliminate the feedback, try using a frequency equalizer to further decrease the feedback
frequencies.
