The Behringer ULTRAGRAPH PRO FBQ3102 is a professional 31-band stereo graphic equalizer with the proprietary FBQ Feedback Detection System, which instantly reveals feedback frequencies by lighting LEDs on the offending faders - invaluable for taming rings during live shows in venues and churches. The FBQ display can also be used as an audio analyzer for quick system tuning. Each channel offers 31 ISO-centred bands plus sweepable low-cut and high-cut filters that remove floor rumble, room resonance and electrical hum, freeing up power amp headroom for cleaner, punchier output. A dedicated mono subwoofer output with adjustable crossover simplifies integration of sub-bass systems in mobile PA and installed setups. Servo-balanced XLR and 1/4" TRS connectors handle professional signal levels, while accurate 12-segment LED input/output metering and input gain controls make level setting straightforward. Rack-mountable in two rack units, the FBQ3102 is a practical mastering tool for live sound engineers, DJs and studios across Kenya.
