Behringer Ultragraph Pro FBQ6200 EqualizerThe
flagship Behringer FBQ6200 Ultragraph Pro is an ultra-musical 31-band stereo graphic EQ that goes the distance to offer a maximum in performance and flexibility both live and in the studio. Its patent-pending feedback detection system instantly reveals feedback frequencies and also can be used as an audio analyzer. A whole battery of superb features includes dedicated limiters with meters for each channel; a pink noise generator; a mono subwoofer output; and sweepable high and low cut filters for each channel. Level setting is no sweat thanks to 8-digit LED I/O metering and input gain control. Top-drawer components include ultra low-noise op-amps, servo balanced 1/4 inch TRS & gold-plated XLR I/Os and relay-controlled hard-bypass. Expect lasting reliability with the high quality illuminated 45-mm faders and detent ALPS pots.
FBQ Feedback Detection

The FBQ Feedback Detection System lets you immediately recognize and eliminate feedback frequencies. Unlike other systems, it is extremely fast-acting, responding within milliseconds. Plus it works as 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. This feedback is often caused by specific room acoustics or characteristics of your sound system.
Our amazing FBQ Feedback Detection System helps you to easily detect and smooth out these irregularities during the sound check and you're ready and done with when the show starts. Once you've got the critical frequencies under control, your system is efficiently protected against feedback and tuned to offer maximal gain reserve.
