The FS-4N Feedback Suppressor is typically connected between the mixer and other effects or processors and/or the
power amplifier in live sound applications. The entire audio in a given setup should feed through the FS-4N so that
you may control all hum, noises and feedback appearing anywhere in the signal you are amplifying. Since both
monitor (if used) and FOH (Front-of-House) amplification may cause feedback, it may be necessary to suppress
frequencies in each loop. Furthermore, you may also be using a stereo FOH mix. Since the FS-4N is a mono unit,
up to three units may be needed in stereo live sound setups for total control of the monitor and each side of the
stereo FOH amplification.
TYPICAL SETUP
NOTE: Insert any processors, EQ’s, etc. between the mixer and the FS-4N. The Feedback Suppressor should be the
last processor in line before connecting the audio to the amplifier.
