FBQ - Totally Feedback-Free
For more than 20 years, BEHRINGER has designed and manufactured some of the most successful
FBQ Feedback Elimination processors. Now you can own and enjoy the bene ts of this technology,
as we have integrated the revolutionary FBQ Feedback Detection System into this product, so your
sound system is completely feedback-free, allowing you to focus on your performance. Utilizingan
ultra-fast feedback detection system, this ingenious circuitry helps you recognize and tame feedback
frequencies immediately. When feedback is sensed in a speci c frequency range, the LED on the
associated EQ fader illuminates, showing you at a glance which fader to lower to overcome the
feedback. That simple!
Ultra-Low Noise Operation
The high-de nition FBQ3102HD provides superb, ultra-low noise performance thanks to top-notch
German engineering, and the use of highest-quality components. Industry-leading 4580 dual
operational ampli ers are employed throughout for the utmost signal integrity across the entire
audio spectrum. With 31-bands of smooth and precise equalization per channel, the stereo
FBQ3102HD adds the  nishing professional touch to your recordings and live shows.
Special Tools for Low and High Frequencies
The low-frequency sound range requires special attention. That’s why the FBQ3102HD features
ultra-precise, variable High- and Low-Cut  lters on each channel, with a sweepable frequency that
helps remove non-essential bass content, such as  oor rumble, room resonance and electrical hum,
etc., which really uses up your power amp’s headroom. This added high-precision control gives the
FBQ3102HD the power to accurately  ne-tune your system’s overall sound, creating crystal clear and
dynamic output – with incredibly tight and punchy bottom-end!
