How to Eliminate Feedback in Amplifiers391

Feedback in amplifiers is a common problem that can cause a variety of issues, including squealing, humming, and distortion. In some cases, feedback can even damage the amplifier or speakers. Fortunately, there are a number of things you can do to eliminate feedback and ensure that your amplifier sounds its best.

What Causes Feedback in Amplifiers?

Feedback occurs when the output of an amplifier is fed back into the input. This can happen in a number of ways, including:* Acoustic feedback: This type of feedback occurs when the sound from the speakers is picked up by the microphone. This can happen when the microphone is too close to the speakers, or when the room is too small or reverberant.
* Electrical feedback: This type of feedback occurs when the output of the amplifier is fed back into the input through the electrical wiring. This can happen when the input and output cables are too close together, or when there is a problem with the amplifier's circuitry.

How to Eliminate Feedback in Amplifiers

There are a number of things you can do to eliminate feedback in amplifiers, including:* Move the microphone away from the speakers. This is the most effective way to reduce acoustic feedback. If possible, place the microphone at least 3 feet away from the speakers.
* Reduce the volume of the amplifier. This will reduce the amount of sound that is fed back into the input.
* Use a feedback suppressor. A feedback suppressor is a device that can be used to reduce feedback. Feedback suppressors work by automatically adjusting the gain of the amplifier to compensate for feedback.
* Check the input and output cables. Make sure that the input and output cables are not too close together, and that there are no kinks or breaks in the cables.
* Have the amplifier serviced. If you have tried all of the above steps and you are still experiencing feedback, you may need to have the amplifier serviced. A qualified technician can diagnose the problem and make the necessary repairs.

Conclusion

Feedback in amplifiers is a common problem, but it can be easily eliminated by following the steps outlined in this article. By taking the time to identify and eliminate the source of feedback, you can ensure that your amplifier sounds its best.
