Shrill feedback from microphones at a live performance is highly undesirable. To combat this high-pitched sound, manufacturers developed audio equipment, such as the Behringer Feedback Destroyer, to prevent it. The Behringer Feedback Destroyer is a 2-channel unit that's widely used and well-respected in the sound reinforcement industry.

Things You Will Need
Determine where in the mixer’s signal path to connect the unit. Your options are:
- One or two individual microphone channels via the mixer's CHANNEL INSERT in/out jacks.
- The monitor mix output via the mixer's MONITOR OUT jacks.
- The main mix output via the mixer's MAIN OUT jacks.
Connect a balanced cable with the appropriate connectors from CHANNEL INSERT OUT jacks on the desired mixer channel to INPUT RIGHT or LEFT on the Feedback Destroyer’s back panel for individual microphone channels. Connect a balanced cable with the appropriate connectors from the OUTPUT RIGHT or LEFT jacks on the Feedback Destroyer’s back panel to that mixer channel’s CHANNEL INSERT IN jack.
Connect a balanced cable with the appropriate connectors from the mixer’s MONITOR OUT jacks to the INPUT RIGHT or LEFT jacks on the Feedback Destroyer’s back panel for the monitor signal path. Connect a balanced cable with the appropriate connectors from the OUTPUT RIGHT or LEFT jacks on the Feedback Destroyer’s back panel to the monitor amplifier INPUT jack or amplified monitor speaker INPUT jacks.
Connect a balanced cable with the appropriate connectors from the mixer’s MAIN OUT jacks to the INPUT RIGHT or LEFT jacks on the Feedback Destroyer’s back panel for the main mix (FOH) signal path. Connect a balanced cable with the appropriate connectors from the OUTPUT RIGHT or LEFT jacks on the Feedback Destroyer’s back panel to the main amplifier INPUT jack or amplified house speaker INPUT jacks.
Warnings:
- Always lower the main volume to minimum before powering on any device in the audio signal path to avoid possible speaker or hearing damage.
