That would work if you knew the exact frequency of the feedback. Unfortunately it isn't always the same frequency. I have had both high and low frequency feedback depending on what sounds were playing at the time the singer got too close to the monitor speaker. And those are only the frequencies within hearing range.
Actually, I was looking at the 2 or 3 models of automatic feedback suppresion units. These are supposed to trigger and set active narrowband filters to block any feedback frequency within 0.1 second or less. I was wondering if anyone had used any of these equipments and did they live up to their hype. Or did they reduce the quality of the overall output.
Thanks Admin, but even though I have spent my entire career both working in and teaching electronics, I would rather let someone else build the equipment, so I don't have to clutter my head with all those calculations.
