Reply To: Vocal mic feedback destroyer channel settings?

[cornelius78]

The geq centres the cut at 1kHz, but will also affect get 1/6th of the octave either side of the centre freq (for a total of 1/3 of the octive for that geq fader: that’s why it’s called a 1/3rd geq.) If you use the peq and get the Q to be narrower (can go as narrow as 1/9th of the octave on the Qu, other desks (eg Midas Pro,) can get even narrower,) you’re cutting out less of the sound and still eliminating the feedback. To borrow an old analogy, using the geq instead of the peq is like using a hatchet instead of a scalpel; it works, but it does a lot of collateral damage in the process. Furthermore, what if the feedback isn’t precisely at 1k, what if it’s a bit higher or lower? The freqs on the geq are fixed and to get rid of the feedback you might have to adjust multiple ones, butchering the sound even further. The peq is sweepable, so you can sweep to the exact frequency that’s feeding back and notch it out properly.
