If you alter the main GEQ you will affect all sound passing through your PA, rather than just the mic that’s causing the problems. Although it may be the case that it’s feeding back there because the PA is producing too much of that frequency.

Input EQ would generally be better, assuming the PA sounds correct.

In the GEQ window you will see red bars lighting up to indicate which frequency is feeding back, though you may have to let it squeal a bit to see this clearly.

“Q” is filter quality. It is basically referring to the bandwidth of the filter (the EQ band). Higher Q values will give a narrower band.
