Graphic Equalizer Behringer FBQ800 V2 31-band 24-bit

The Behringer FBQ800 V2 31-band 24-bit graphic equalizer provides precise tonal control for live sound rigs, rehearsal spaces and studio installations. With 31 individual frequency bands and 24-bit internal processing, the unit allows subtle to significant frequency shaping to correct room response, reduce feedback and improve mix clarity. The FBQ feedback detection system highlights problematic frequencies on the front panel, helping users identify and attenuate feedback-prone bands quickly. Rack-mount format and straightforward controls make it suitable for integration into PA systems, monitor chains and outboard processing setups.

Advantages

The FBQ800 V2 combines high-resolution 24-bit processing with a full 31-band layout to offer detailed equalization across the audible spectrum. The FBQ feedback detection function simplifies feedback control by visually indicating offending bands, reducing the need for trial-and-error adjustments. Its balanced I/O and standard rack width provide flexible connectivity and easy installation in live and studio racks. The control layout and durable construction support reliable operation during repeated setup and transport.

Suitable for

• Live PA systems for tuning house sound and eliminating feedback
• Stage monitor mixes to increase intelligibility for performers
• Rehearsal rooms and venues for correcting room acoustic anomalies
• Recording and mixing chains where precise tonal shaping is required

Key specifications

• 31 graphic bands covering the audible frequency range for fine adjustment
• 24-bit internal processing for high resolution EQ operations
• Front-panel FBQ feedback detection for visual identification of critical frequencies
• Balanced inputs and outputs for reduced noise and improved signal integrity
• Rack-mount design compatible with standard 19-inch racks
• Detented sliders for repeatable settings and accurate recall

How to use

Insert the FBQ800 V2 into the signal path between your mixer and power amplifier or between the mixer and monitor sends as required. Set all sliders to the flat position, play program material or have a performer sing or play while adjusting individual bands to achieve the desired tonal balance. Use the FBQ feedback detection to locate frequencies that produce feedback and attenuate those bands slightly until stability is achieved. For subtle shaping, make small incremental adjustments; for corrective work, more pronounced cuts in problematic bands can be applied.

Recommendations

For live setups, perform a soundcheck with the full band or vocal source to identify resonant frequencies and use the FBQ indicator to address feedback quickly. When shaping mixes in the studio, use reference material and moderate settings to preserve natural sound; record dry and apply equalization as needed during tracking or in the monitoring chain to inform mix decisions.
