Behringer FBQ2496 FEEDBACK DESTROYER PRO Feedback reduction

Behringer FBQ2496 Feedback Destroyer Pro — Ultra-Fast Feedback Suppression for Live Sound

This 2-channel, 1U rack-mount feedback suppressor and parametric EQ features the fastest detection on the market (less than 0.2 seconds) and remains the only unit in its class offering a 96 kHz sampling rate. Live performers, houses of worship, and touring engineers rely on this model for automatic, transparent feedback control.

What Sets the FBQ2496 Apart

Proprietary FFT-based detection algorithms locate up to 20 feedback frequencies per channel and apply ultra-narrow notch filters as tight as 1/60th of an octave — surgical cuts that remove the offending ring. Paired with 32-bit DSP, the 24-bit/96 kHz A/D and D/A converters deliver a frequency response extending below 10 Hz up to 44 kHz, so the suppressor adds no audible coloration.

Technical Parameters — Speed, Precision, and Connectivity

The numbers behind this instrument explain why it has become a staple in live rigs.

• Detection Speed: less than 0.2 seconds — proprietary FFT analysis catches feedback before the audience notices
• With notch filter bandwidths reaching 1/60th of an octave, the device performs surgical suppression while leaving program material untouched.
• Filter Count: up to 40 total (20 per channel) — enough headroom for complex monitor mixes and PA mains
• Converter Resolution: 24-bit / 96 kHz A/D and D/A converters running on a 32-bit DSP engine — flagship-grade signal path with no audible coloration
• Dynamic Range: 107 dB with THD: 0.007% typical — quiet sources stay quiet, loud sources stay clean
• Connectivity: balanced XLR and 1/4" TRS inputs and outputs, plus 5-pin DIN MIDI IN / OUT / THRU for preset recall and remote control from a console or footswitch
• Form Factor: 1U rack, 44.5 × 482.6 × 190.5 mm, 1.9 kg — drops into any standard rack case

Who the FBQ2496 Is For

The FBQ2496 suits live sound engineers, worship tech teams, and small-to-mid touring acts who need automatic, hands-off feedback control on mono PA mains, monitor mixes, or both. Auto Mode continuously monitors the mix and resets filters in real time, freeing the engineer to focus on the band. Single-Shot Mode locks detected feedback filters until manually reset — useful in fixed installations. Manual Mode hands full parametric control for creative EQ shaping.
