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 FBQ1502HD 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.

How Does Equalization Work? Imagine the audio frequency range as a very wide highway with lots of “lanes”. 

Each of these lanes represents a specific frequency band.

The lanes on the left side contain the really low frequency content, mainly bass, bass vocals, and the kick and tom drums

The middle lanes make up the fundamental zone of most musical instruments and the male and female vocals

The right-hand lanes have all the highfrequency stuff, such as snare drums, cymbals, higher pitched percussion instruments and the content that adds sizzle to the mix.

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!
