Behringer 000-B3S FBQ3102HD 31-Band Stereo EQ

The Behringer FBQ3102HD is a dual-channel, 31-band graphic equalizer built for both live sound reinforcement and studio signal processing. Each channel provides 31 frequency bands with individual sliders, giving you precise control to shape the tonal character of your audio signal. The standout feature is the FBQ Feedback Detection System, which uses LED indicators on each slider to visually highlight frequencies that are feeding back — an invaluable tool during live performances where quick identification and suppression of feedback can save a show.

Beyond the core EQ functionality, each channel includes sweepable high-cut and low-cut filters that let you set custom cutoff points to eliminate unwanted noise such as stage rumble, HVAC hum, or high-frequency hiss before it reaches the equalization stage. The dedicated mono subwoofer output with adjustable crossover frequency is a practical addition for live rigs, allowing you to send bass content to a subwoofer directly from the EQ without requiring a separate crossover processor. Housed in a standard 19-inch rack format and weighing just under 6 pounds, the FBQ3102HD fits easily into existing rack setups. The analog signal path keeps latency at zero, and the USB 2.0 hardware interface provides additional connectivity options.
