dbx FCS-966 Graphic Equalizer

The dbx FCS-966 Graphic Equalizer is a two channel graphic equalizer that provides a generous +/-15dB of control range on each of 30 constant Q frequency bands. For optimum performance, each filter band is arranged to be out of circuit if it's sliders are left in the center of its travel, and thus does not contribute unnecessary noise or distortion.

The dbx FCS-966 Graphic Equalizer is designed to render sweetness 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 the dbx 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 DBX Pro, 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 +/-15dB of adjustable gain, more than many competitive graphic eq's. The faders are long-throw 45mm types for precision control.

High Pass Filter

Also provided on the dbx FCS-966 Graphic Equalizer 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

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

Centre Bypass

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

Input/Outputs

All the inputs and outputs of the dbx FCS-966 are electronically balanced, with optional transformer balancing. To make installation of the dbx FCS-966 easier, they've provided three differerent 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 centres, each with nominal +/-15dB of gain. Positive centre-detent on 45mm long-throw precision faders.
  • HP Filter Sweepable high pass filter, frequency adjustable from OUT (flat) up to 250Hz.
  • LF Contour: Smooth shelving filter, +/-6dB of gain at 50Hz
  • HF Contour: Smooth shelving filter, +/-6dB of gain at 14kHz.
  • Gain: Used for overall unity gain adjustment. Adjustable from - infinity to +10dB.
  • 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 -24dBu to +18dBu in 8 steps.
