Line 11:

# Turn the volume down on the microphone channel

# Turn the volume down on the microphone channel; mute any other microphone channels.

# Set the Para EQ Level to 10 dB boost (boost, not cut)

# Set the Para EQ Width to 0.20 oct

Line 22:

If there are multiple microphones in the system you may find that the whole system feeds repeat this procedure ~~if necessary~~ for the other microphones.

If there are multiple microphones in the system you may find that the whole system feeds; if so, repeat this procedure for the other microphones (muting the other microphones while adjusting the Para EQ on one of them).

~~Then, once~~ you know the frequency (and the T1 tells you this in Hz), you can ~~apply~~ the same notch to other microphones.

Once you know the frequency for one microphone (and the T1 tells you this in Hz), you can start by applying the same notch to other microphones -- but you may find that some adjustments are needed for each due to differences in the microphones and their different locations.

How much does this hurt the sound? You should experiment a little, since - it depends. The notch will have different effects on the tone depending on how deep it is (how much you cut), how wide it is (keep it as narrow as you can), and where it is relative to your voice or instrument. Use your ears to tell you if you've gone too far.

This technique was described in [[T1 ToneMatch® Audio Engine / Using the Para EQ to Control Feedback - field report|a field report]] by Bill-at-Bose.

Here is a video about the relationship between the ToneMatch Presets, zEQ, ParaMetric EQ.
