With the digital capabilities we’ve just listed, it’s easy to see why we were able to include a highly-effective Feedback Destroyer (FBQ) feature – it’s essentially a dynamically-activated parametric EQ that “watches” the whole frequency spectrum in 1∕60-octave bands and then instantly identifies and notches out feedback. FBQ can be run in AUTO mode, or in Single mode. We’ve also included a Learn mode that generates short audio pulses, raises their gain until feedback occurs, and then locks onto feedback-prone frequencies. For more than 20 years, we have made some of the world’s most acclaimed FBQ Feedback Elimination processors. Now you get this revolutionary FBQ Feedback Detection System in every DEQ2496, so your sound system is always completely free from feedback. Utilizing an ultra-fast detection system, this ingenious circuitry helps you recognize and tame feedback frequencies immediately. LEDs on the associated EQ frequency-band fader illuminates, showing you at a glance which fader to lower to overcome the feedback – it doesn’t get any easier than this!
