STEP 4: Slowly increase the amplitude of the microphone signal in the loudspeaker; to the point of oscillation (“ringing”).

STEP 5: Using the equalizer, set the EQ filter to the appropriate frequency and decrease 2-5dB

Repeat steps 4 and 5 until the desired GBF is achieved.A good stopping point is when the fader has reached 0dB or you can speak from about 30-50 feet from the podium and be heard through the loudspeakers.This should provide a good starting point from which to use the lapel microphone for the service. - Bill Johnson
