For best results, read all operating instructions
before using the FBX-SOLO (pages 12-19).
1.
Patch in the SOLO where appropriate
for your model, and select the input/
output level on the back.
2.
With gain down on the input channel,
put the SOLO in Active mode (green
bypass LED), then slowly raise the
channel gain to the point of feedback.
3.
Raise the gain slowly until 7 FBX filters
are set, then reduce gain slightly.
4.
Adjust the Clip Level on the SOLO, and
you're ready to go.

  • Page 1 LED), then slowly raise the channel gain to the point of feedback. Raise the gain slowly until 7 FBX filters are set, then reduce gain slightly. Adjust the Clip Level on the SOLO, and you're ready to go. © 2003 Sabine, Inc.
  • Page 2 CONGRATULATIONS! You now have the state-of-the-art in feedback con- trol. The Sabine FBX-SOLO gives you automatic real-time feedback control for any channel of your mix. In setup and during the performance, it gives you more gain and increases the clarity of your mains and monitors.
  • Page 3 THE 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 4 A DIRECT HIT ON FEEDBACK! The 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 5 SL820 & SM820 FRONT PANELS POWER The On/Off power switch is a two-position push button switch. The LEDs corresponding to all active filters will blink on power-up. ACTIVE/BYPASS In Active mode, the unit controls feedback auto- matically. The two-color "BY" LED lights green when the unit is in Active mode and lights red when in Bypass mode.
  • Page 6 Recommended setting of the Clip Level Adjust: the clip LED should blink intermittently. Regardless of the Clip Level Adjust, setting Unity on the back panel will maintain unity gain (no net gain or loss of signal level). When the back panel output is set to Line, the SOLO acts as a preamplifier, and the Clip Level Adjust knob becomes a gain control (see SL820 &...
  • Page 7 OUTPUT UNITY/LINE SWITCH Switch to Unity (for level in = level out) for use with amplifiers that accept low level signals, such as guitar amps. In the Unity setting, the SL820 input level equals the output level. Switch to Line (for line level out) if your signal needs pre-amplification.
  • Page 8 APPLICATIONS SL820: You can use the SL820 with acoustic/electric guitars and guitar SL820 amplifiers, mixer insert points, pow- ered mixer patch points and high impedance mics. Use the following wiring diagrams as guides for setup: NOTE: For Configurations 1-4, the output control on the back panel of the SL820 may actually be set to either Unity or Line.
  • Page 9 4. Instrument IN for Amp NOTE: an SL820 can be inserted at line level after the mixer and before the power amp on smaller systems. Note for SM820: Use the SM820 with balanced microphones. SM820 5. Mic Input to Mixer Line Input 6.

  • Page 11 signed frequencies (configured during setup). In- creased activity at one of those frequencies may cause the filter to go deeper (e.g.., deepen from -12 dB to -15 dB). Activating the Lock Fix function prevents the Fixed filters from going deeper at their assigned frequencies.
  • Page 12 (the Lock Fixed light will turn on), then press it again. (Lock Fixed light will go out). MOBILE vs. STATIONARY MICROPHONES One significant advantage offered by the Sabine family of FBX Feedback Exterminator products is their ability to adapt to changing acoustical relation- ships involving sound system components and vari- ous user applications.
  • Page 13 same time, raise the system gain and set the FBX filters one at a time. In some situations, raising the number of dynamic filters (versus fixed FBX filters) may allow a second layer of defense against new feedback from new locations.
  • Page 14 FBX SETUP INSTRUCTIONS Place the speakers and micro- phones in the positions where they will be used during the program. Avoid placing microphones di- rectly in front of speakers. If you are using a graphic EQ, adjust it only for the desired tonal quali- ties.
  • Page 15 Slowly raise the in- put channel level fader for the channel being set until feed- back occurs. The CHANNEL FIRST SOLO should quickly INPUT FEEDBACK LEVEL TONE remove the feedback. The first Filter LED will then blink to indicate a filter has been set.
  • Page 16 HOW TO USE THE "LOCK FIXED" FEATURE In certain situations the FBX may mistake music for feedback and drive the fixed filters deeper than necessary, like in a church with a pipe organ or during a performance with a great deal of intentional sustained electric guitar feedback.

  • Page 18 phone preamp still functions when the unit is in bypass mode. The SOLO will not pass signal if the power is off in either active or bypass mode. RESETTING THE FILTERS: You must reset the FBX if the microphones or speakers are moved significantly.
  • Page 19 Q. Why does my SOLO set filters when music is played through it? A. Make sure the FBX’s Turbo Mode has turned off before you program. Check the signal level ladder. If the red Clip LED lights with no other signal level LEDs lit, the FBX-SOLO is still in Turbo Mode.
