What Is a Feedback Destroyer?

The Feedback Destroyer is a 2-channel unit that helps eliminate high-pitched feedback on audio signals. It can be connected to individual microphone channels or the main mix output. It also has a manual mode, which allows the user to adjust individual parameters. The Feedback Destroyer is rack-mountable.

The Feedback Destroyer is extremely easy to use. There are push buttons on the back panel that allow you to change the level of the feedback. You can set the Feedback Destroyer to operate at -10 dBV for home recording, or up to +4 dB for professional studio use. The manual makes a false claim that the device will automatically nuke feedback within 0.2 seconds. While it might work, it will take some time to learn what frequencies cause feedback. In the meantime, you may end up blowing your speakers and eardrums.

Once you've identified the source of the feedback, the next step is to eliminate it. It can be caused by a variety of factors, including the placement of the monitor or mic in relation to the walls or ceiling. In this case, the feedback destroyer can be used to eliminate the problem, or to add a limiting filter to a signal.

Is a Feedback Suppressor Right For Your Application?

A feedback suppressor is an audio signal processing device used in the signal path of a live sound reinforcement system. Its primary purpose is to prevent audio feedback from being generated. These devices are available in a variety of designs. Regardless of how they are used, they will help you avoid audio feedback in your live performance.

A feedback suppressor works similarly to an automatic cut-only Parametric Equalizer. It uses floating bands of equalization to detect feedback frequencies and suppress these frequencies. A feedback suppressor should be used in conjunction with speaker time alignment and system EQ to achieve the best result. Whether or not a Feedback Suppressor is right for your application depends on how much time and energy you are willing to invest.

A feedback suppressor can handle up to four microphone inputs. It is best to use two microphones for better capture of a speaker's voice. The risk of acoustic feedback is greater when a speaker is in motion. A feedback suppressor's automatic mixer will automatically adjust the gain of weak signals, while increasing the gain of strong signals. This allows it to follow a speaker while in motion while maintaining maximum volume without acoustic feedback.

Automatic Feedback Suppression is a very useful feature for a feedback suppressor. It monitors the incoming audio and places narrow notch filters at each frequency to reduce the amount of feedback. The 1/80 octave filters are extremely precise, so they can cut out the offending frequencies without affecting the rest of the spectrum. Moreover, they also help to preserve the overall sound quality.

Using an Audio Feedback Suppressor

An audio feedback suppressor can be a great solution for dealing with feedback in a variety of settings. Its advanced feature set, including a built-in automatic mixer, will help you get the maximum volume without acoustic feedback. It is also flexible, which makes it easy to use.

The Automatic Feedback Suppression algorithm monitors audio for feedback, and then places narrow notch filters at each frequency. These filters cut out the offending frequencies, while maintaining the rest of the frequency spectrum. This process takes milliseconds, and it completes before the human ear can detect abnormalities.

Digital feedback suppressors come in different levels of effectiveness. The more advanced models can produce acceptable results. The cause of feedback varies with each environment. Frequency response of microphones, room resonant frequencies, and musical instruments characteristics are just some of the factors that may influence feedback. So, the first step in removing feedback is to determine the frequency of the problem.

Typically, commercial sound systems are designed with feedback control in mind. But even with these precautions, feedback may occur. For example, a soft-spoken presenter can bring a hand-held microphone too close to the speaker system, resulting in feedback. In this case, the sound system's volume may need to be increased to compensate.
