BSS Audio FCS-960 Dual 30-band Graphic EQ

The BSS FCS-960 is a dual-channel 30-band graphic EQ built around BSS's Frequency Conscious filter design — a proprietary approach where cuts behave with a narrower Q and boosts open up wider. That asymmetry matters in real ring-out work: you can notch a feedback frequency tightly without gutting the surrounding octave, then add a gentle presence lift without creating a harsh spike. Two fully independent channels in 2U means a single unit handles a stereo IEM mix or two discrete monitor sends, which is exactly how most touring monitor racks use it.

At 240mm deep and 5.8kg, the FCS-960 sits comfortably in a standard shallow rack without fighting for real estate, and 24 watts idle means it won't stress a modest power strip. Both channels are XLR in and out — balanced, line level throughout — so there's no adapter gymnastics patching it between a console aux and a drive rack or amplifier. The faders are long-throw and well-spaced for a 30-band unit, which makes precise adjustments under stage lighting less of a guess. Thirty bands at ISO centers gives you the resolution to chase a specific monitor build's resonances without the coarse compromises of a 15-band.

If your workflow is analog monitor world or you're maintaining a touring rig that needs a physical graphic in the chain, the FCS-960 earns its rack space. Engineers who prefer its filter character over the Klark DN360 often cite a slightly warmer quality in the low-mids when boosting. If you're running a fully digital signal path with a console that already provides per-output GEQ — an SD-Range or a DiGiCo with internal processing — a hardware graphic may be redundant weight and cost. Similarly, if you only need one channel, look at the single-channel FCS-966 before doubling your rack space.
