FBQ - Totally Feedback-Free
For more than 20 years, 
 has designed and manufactured some of the most successful 
FBQ Feedback Elimination processors. Now you can own and enjoy the benefi ts of this technology, 
as we have integrated the revolutionary FBQ Feedback Detection System in 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 specifi 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!
