Microphone Feedback Problem

JojoD818 · 30th June 2003, 10:42 AM

Hi,

Is there a circuit that I can build to reduce if not eliminate the feedback when I use my microphone?

Thanks in advance!

Standard equipment is a 1/3 octave graphic equaliser to cut the problem frequencies.

There are also frequency shifters (shift by 1Hz, or so). Surrey Electronics makes them.

However, by far the best solution is to put the microphone nearer the source (reducing required gain) - that's why you see the likes of Britney with a diddy mike looping round her face and kissing her lips. Cardioid response helps too.
