The FBX-SOLO SM820 is a single channel miniature version Feedback Exterminator based on the FBX-1020Plus. This solution for feedback control hosts several new features, including increased headroom, a programmable noise gate, and switchable input/output levels for more versatility. This model features XLR connectors for use with both dynamic and condenser microphones in various applications.
The SM820 targets feedback without taking a big sonic chunk out of the source material, since digital FBX filters are 10 times narrower than graphic EQ filters. The unit functions by precisely detecting the feedback frequency, and placing super-narrow (1/10 octave) digital filters directly on these frequencies, and finally setting the filters just deep enough to remove the feedback. The results are more gain, increased intelligibility - narrow filters target the feedback and leave the source material untouched - and automatic feedback control, both in setup and during a performance.
FBX filters come in two flavors. Fixed and Dynamic. Both types are placed the same way - feedback is detected and the filter is placed just deep enough to eliminate it. The difference comes after the filter is placed. Fixed filters remain on the initially detected feedback tone - they do not move. These filters provide the initial maximum gain before feedback and are set automatically during setup. Dynamic filters can release and move to new feedback frequencies and are for adaptive feedback control during the performance.
The FBX-SOLO SM820 is the perfect solution for wireless microphones, since performers are able to move freely without worrying about feedback. For locations like conference rooms and courthouses, the built-in noise gate provides the additional control needed in multi-microphone set-ups.
