Offering the ultimate ease of operation, the FS-4N is the straightforward solution to feedback and hum problems in live sound applications.

Single rack space (1U) rugged metal housing for reliability

Four extremely narrow (1/60 octave) notch filters, each independently adjustable from 60 to 6,000 Hz, allow quick elimination of unwanted problem frequencies without affecting the integrity of the overall sound.

A control for adjusting the notch depth on each filter enables precise attenuation (up to -20 dB) at each selected frequency.

A push button bypass switches all four notches in and out simultaneously for fast monitoring of results during use.

An in-line 8-band audio spectrum analyzer LED display enables quick identification of the frequency range of any problem frequency, facilitating immediate reaction and suppression by the operator.

1/4" TRS balanced jacks for both SIGNAL IN and OUT

Internal shielded power supply with external fuse and ~115V (60Hz) / ~230V (50Hz) AC select switch

IEC power cord socket for AC operation and screw terminals for optional +24 VDC input powering
