BSS Audio Opal FCS-966 — 2-Channel 30-Band Constant Q Graphic Equaliser
About this product
One of the most trusted tools in professional live sound — a dual-channel, 30-band constant-Q graphic equaliser for system tuning, feedback control and house curve management. A staple piece of outboard for any properly specified PA hire package.
30 bands of ISO-standard 1/3-octave EQ per channel spanning 20Hz to 20kHz, implemented in BSS's constant-Q design — meaning consistent bandwidth at every band regardless of cut or boost depth, avoiding the colouration you get with variable-Q designs. Bypass switch for A/B comparison during system setup, output level control with LED metering, and BSS's built-in GEQ limiting to prevent output clipping when multiple bands are boosted. Balanced XLR I/O on both channels.
