FBX-SOLO
Model SM-620
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.

  • Page 2: About The Fbx

    ABOUT THE FBX... WORLD'S BEST FEEDBACK CONTROLLER: Before the invention of the FBX, the most common device for controlling feedback was the 31-band graphic EQ. However, the FBX has three distinct advantages. The most obvious is the FBX functions automatically, even during the program. Another is the FBX micro- filters are precisely placed while EQ filters are fixed.
  • Page 3 A DIRECT HIT ON FEEDBACK! 0 dB FBX-SOLO targets feedback without taking a big chunk out of your sound. Tests prove that a single 1/3-octave EQ slider pulled down 12 dB removes almost half the power going to the speakers over a two-octave range.

  • Page 10: Operating Instructions

    INSTRUCTIONS FOR OPERATION SL-620 SYSTEM INITIALIZING PROCEDURE Choose the input level. Switch to LOW for instrument or microphone in (use with low level inputs such as piezo mics); this provides a 30dB boost in the FBX's input gain struc- ture. Switch to HIGH for insert or line in (use with high level output instruments and signal processors).
  • Page 11 Select Phantom Power ON/OFF. Your SM is delivered from the factory with the phantom power function disabled. If you wish to use phantom power, you may enable the function by switching to "PHANTOM POWER - ON" on the back panel. The majority of low impedance balanced non-phantom-powered mics are wired to ignore phantom power.
  • Page 12 1-U rack tray (model #SL6RACK): An optional 1-U rack tray holds up to six SOLOs. Mount the SL-620s, SM-620s, or a combination of both side by side on the tray. Use only Sabine supplied screws; use of any other screws may damage the SOLO and void the war- ranty.

  • Page 13: Troubleshooting Tips

    TROUBLESHOOTING TIPS Q. Can I patch the SOLO SL-620 after the mixer and before the power amp, just like other FBX models? A. Yes, but only in cases where just six feedback filters are needed, such as on the moni- tors alone.
