How to avoid Feedback

Feedback is the annoying howling and squealing that can heard when the microphone picks up sound from a speaker. The sound is then re-amplified back through the speaker again, creating a feedback loop. Follow these steps to minimize the likelihood of feedback:

• Avoid pointing the microphone directly at the speakers. In general it is recommended that the microphone be positioned behind the speaker enclosures. This uses the directional characteristics of the speakers and microphone to your advantage.

• Keep the microphone as far from the speakers as possible. This will help achieve isolation between the speakers and the microphone, and allow you to increase the overall output.

• Position the microphone as close to the sound source as possible. This will enable the microphone to pick up more direct sound, and allow you to reduce the microphone input gain control.

• Reduce the overall level of the speakers.
