CONGRATULATIONS!

You now have the state-of-the-art in feedback control. The Sabine

FBX-SOLO

gives you automatic real-time feedback control for any channel on your mix. In

setup

and

during the performance, it gives you more gain and increases the clarity of your

mains and monitors. It's the affordable solution to feedback problems, perfect for wireless

mics, monitors, acoustic/electric instruments, harmonica mics, multi-mic locations like

conference rooms and courthouses -- wherever there's an open microphone.

The FBX-SOLO

incorporates the latest in design and digital signal processing technology.

It automatically senses feedback in a sound system and determines its pitch. It then places

one of its six constant "Q" micro-filters on the resonating frequency and eliminates the

feedback in typically less than one second.

Special features of the SL-620 and SM-620:

• The SL-620 has

1/4" in/out connectors

and

input/output level switches

for any

combination of ins and outs. The SL is for use with acoustic/electric guitars and guitar

amplifiers, mixer insert points, powered mixer patch points and high impedance mics.

• The SM-620, with

selectable phantom power,

has

XLR in/out connectors

for use with

balanced microphones.

• Both models offer standard FBX features like

switchable filter widths

and

lockable

fixed filters.
