The Behringer Ultragraph FBQ3102 is a 31 band stereo graphic equaliser with FBQ Feedback Detection System. 

It features a Low Cut filter, in addition to the frequency faders, to help remove unwanted low frequencies such as floor rumble, room resonance, electrical hum, etc.

All three FBQ-PRO models feature a dedicated subwoofer output with an adjustable (30 – 200 Hz) cut-off frequency. Balanced XLR Outs are provided so you can connect to power amps, or directly to your active subwoofers, without any additional hardware.

The FBQ Feedback Detection System helps you recognize and eliminate feedback frequencies immediately. 

When feedback is sensed in a specific frequency range, the LED on the associated fader lights, so you know at a glance which fader to lower to eliminate the feedback.

FBQ6200 has switchable Limiters per channel with separate Threshold controls, long-throw 45 mm frequency faders for added precision, and a built-in Pink Noise generator that enables the FBQ6200 to pull double-duty as an audio spectrum analyzer.
