Set the equalizer for the monitor channel being set to flat with all of the sliders at their
center detents.
Slowly bring up the microphone gain until feedback occurs. Cut the level of the
frequency band that the feedback occurs in. It takes practice to know which frequencies
are in each band. As soon as the first tone disappears, increase gain more and a new
tone will begin to build. Again, reduce the slider for the corresponding frequency.
Continue this procedure until tones start to come on in multiple frequencies. At this
point, you are probably done. Expect to actually remove from 1 to 4 tones.
Repeat the procedure for the other monitor channels.
Additional adjustments may then be done by taste for best sound or intelligibility.
Please remember, no method is perfect, experiment.
