Keep in mind if the performer moves to a different position, the sound reaching the mic will change, and feedback could occur. Find the setting where you get the maximum volume possible without feedback. Once you've improved placement of the performer (with the mic) and the speaker, adjust the volume UP until feedback starts to occur, then turn it DOWN, to a little bit below the level where feedback starts to occur. It will allow the performer to hear themselves the best, but the audience won't be able to hear as well.ДЇeedback is more likely at higher volumes because the sound is able to spill around corners from the speaker into the microphone.

This arrangement is less resistant to feedback than 1a above. This arrangement has the mic and the speaker 'looking' in the SAME direction, and the mic is not pointed at the speaker.

Position the speaker in front of the performer, pointing at the performer.

This arrangement is the most resistant to feedback, and makes the most sense for karaoke. This arrangement has the mic and the speaker 'looking' in the OPPOSITE direction, AWAY from each other.

Position the speaker in front of the performer pointed at the audience.

Improve the placement of the performer (with the mic) relative to the speaker.

This won't work with any system and is a recipe for a bad time. This arrangement has the speaker and mic 'looking' directly at each other. If they can see each other, you're probably going to get feedback.Дon't position the speaker behind the performer (with the mic) pointing at the back of the performer's head. To help visualize this.imagine that the head of the mic, and the face of the speaker both have eyeballs. To do this, you need to minimize the amount of amplified that is sound coming out of the speaker and going back into the microphone. So, to avoid feedback, you need to prevent the mic from hearing itself. What causes feedback, and how can I prevent it?ДЇeedback can occur any time a microphone can hear 'itself' being amplified by the speaker.

These tips apply to small karaoke setups or large stage venues alike and are the first measures you should take to reduce feedback in your setup. We've put together some common steps that should be taken with any system, large or small, to reduce theВ likelihood of feedback. Feedback is possible any time you have a microphone that is amplified by a speaker or PA system.
