Professional audio engineers have known for decades that a good EQ makes all the difference in how a performance is perceived. Although multi-band graphic equalizers have been around for a long time, they have changed very little until now! The ULTRAGRAPH PRO FBQ3102HD takes the graphic equalizer into the realm of high-definiton audio, providing robust features and our proprietary FBQ Feedback Detection System at a price that makes them a must-have for anyone who records or operates a live sound system.

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 benefits 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 specific 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-definition 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 amplifiers are employed throughout for the utmost signal integrity across the entire audio spectrum. With 15-bands of smooth and precise equalization per channel, the stereo FBQ3102HD adds the finishing 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 an ultra-effective Low-Cut filter on each channel, to help remove non-essential bass content, such as floor 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 fine-tune your system’s overall sound, creating crystal clear and dynamic output with incredibly tight and punchy bottom-end!
