The alphaton Feedback-Controller FC-100 is a revolutionary product for every microphone application including wireless types. It can provide effective feedback control to any sound reinforcement situation. It can also eliminated string feedback in guitars and bass instruments which are equipped with piezo or condenser pickups. The FC-100 provides 6 to 10 dB of feedback protection by analysing the incoming signal, detecting the presence of feedback and then notching out the feedback frequency.

The FC-100 relieves the sound engineer automatically. It works dynamically and eliminates a feedback signal before it can grow into a peak. Internally a discriminator circuit detects the presence of regenerative feedback and triggers the automatic equaliser to insert a notch where the feedback peak is coming up. This normally prevents other peaks from developing but if they do, the process is repeated at high speed, thus keeping feedback under control.
