Nady FS-4N Rackmount Notch Feedback Suppressor

The FS-4N from Nady is a feedback suppressor that offers versatile features in a slim 1RU rackmount metal chassis. It features 4 extremely narrow notch filters, each of which is independently adjustable from 60Hz to 6kHz to allow quick elimination of unwanted problem frequencies without affecting the quality of your overall sound. Controls for adjusting the notch depth on each filter let you precisely attenuate each selected frequency by up to -20dB. A push button bypass will switch all 4 of the notches in and out simultaneously for live monitoring.
