The FBQ Feedback Detection System lets you immediately recognize and eliminate feedback frequencies. Unlike other systems, it is extremely fast-acting, responding within milliseconds.

The FBQ Feedback Detection System also provides the function of a spectrum analyzer. A spectrum analyzer helps to identify frequency areas whose energy levels are significantly higher or lower than the rest of the musical program. Often caused by specific room acoustics or characteristics of your sound system, these frequencies cause feedback. Our amazing FBQ Feedback Detection System helps you to easily detect and smooth out these irregularities during the sound check and youre ready and done with when the show starts. Once youve got the critical frequencies under control, your system is efficiently protected against feedback and tuned to offer maximal gain reserve.

The ULTRAGRAPH PRO FBQ1502 is a professional, ultra-musical 15-band stereo graphic equalizer that is equally at home in both live and studio applications. It features the amazing, patent-pending FBQ Feedback Detection System that instantly detects feedback frequencies and can also be used as an audio analyzer, making the FBQ1502 a welcome addition to any touring rack. Another FBQ1502 highlight is its dedicated mono subwoofer output with adjustable crossover frequency that lets you add some extra punch to your music.

An additional low cut filter removes unwanted frequencies such as floor rumble, while a highly accurate 4-digit LED output metering and input gain control let you easily adjust levels.
