    Overview
    Graphic equalizers are found in just about every sound application, from room contouring to feedback control and general audio sweetening.

    Traditionally, much general eq'ing takes place on the faders alone, but this restricts the use of the faders at each end of the scale for further precision eq work. So we provided the Opal FCS-966 with separate LF and HF contour filters which can change an overall sound balance without disturbing a detailed room or loudspeaker response.

    These filters are very musical gentle boost and cut shelving filters which can be used to add (or remove) room effects that change with temperature, audience numbers or humidity.

    All these effects can be easily made without disturbing the critical fader settings already made.
    Constant Q Filters
    The modern generation of graphic eq's
    uses the Constant Q topology, pioneered by BSS Audio, which means that the filter width is constant whatever the fader gain setting.

    Compared to the earlier 'gyrator' style of filters, Constant Q filters provide a smoother and more predictable interaction between adjacent faders and the resulting eq curve more closely resembles the actual fader positions.

    More Gain Control Per Filter
    Each eq fader has +/-15 dB of adjustable gain, more than many competitive graphic eq's. The faders are long-throw 45 mm types for precision control.

    High Pass Filter
    Also provided on the FCS-966 is a sweepable high-pass filter which can be used very effectively to restrict the low-energy output for better amplifier and loudspeaker performance. Stage monitors also benefit from the application of a high-pass filter to remove bass signals e.g. from vocal-only wedges.

    Metering
    BSS Audio believes in providing engineers with information, and the FCS-966's 8-segment led meter shows output level and warns of signal clipping within the eq. When the unit is switched to bypass, the meter will read the input level, allowing accurate matching of the 'dry' and equalized signals using the gain control.

    Center Bypass
    When any eq fader is in its center detent position, the filter is automatically bypassed, for optimum performance.

    Input/Outputs
    All the inputs and outputs of the FCS-966 are electronically balanced, with optional transformer balancing. To make installation of the FCS-966 easier, we've provided three different interface connectors: XLR-type, 1/4" TRS jack and Phoenix/Combicon screw terminals.

    Relay Bypass
    The EQ IN buttons switch the EQ path
    into circuit. When switched out, or power fails, a high-quality relay switches the input signal directly to the output connectors.

    Control Descriptions

    Faders
    30 EQ filter faders on ISO centers, each with nominal +/-15 dB of gain. Positive center-detent on 45 mm long-throw precision faders.

    HP Filter
    Sweepable high pass filter, frequency adjustable from OUT (flat) up to 250 Hz.

    LF Contour
    Smooth shelving filter, +/-6 dB of gain at 50 Hz

    HF Contour
    Smooth shelving filter, +/-6 dB of gain at 14 kHz.

    GAIN
    Used for overall unity gain adjustment. Adjustable from - infinity to +10 dB.

    CLIP
    Triple-point clip detector that indicates red when the internal signal is clipping at any one of three critical points.

    LED Meter
    Shows output signal level (input signal when eq is bypassed) from -24 dBu to +18 dBu in 8 steps.
