Product Overview

The BSS 966FCS is a professional dual-channel graphic equaliser designed for live sound reinforcement, touring and installed audio systems. It provides precise frequency shaping and feedback control for Front of House and monitor mixes, helping optimise system performance in challenging acoustic environments.

The unit features two independent 31-band graphic EQ channels, each with ±15 dB of gain control per band. Balanced input and output connections using XLR connectors allow straightforward integration into professional analogue signal chains. The 966FCS also includes a switchable high-pass filter and signal present LEDs to support accurate system setup and monitoring.

Housed in a 1U rack-mount chassis, the 966FCS combines robust build quality with reliable operation, making it suitable for touring racks, fixed installations and rental fleet use where flexible, high-resolution equalisation is required.
