1231 Dual 31-Band Graphic Equalizer The dbx? 12 Series were designed to meet the needs of the most demanding sound reinforcement environments, while offering the simplicity of straightforward controls. The 1231 provides standard features like dual-channels, 31 1/3 octave bands, ISO frequency centers, +/- 12 dB input gain range, and switchable 40Hz/18 dB per octave low-cut filters, but also includes other insightful features. These include 45 mm faders; selectable +/-6dB or +/-15dB boost/cut range for precise gain adjustments; XLR, barrier strip, and 1/4'' TRS connectors for installation ease; balanced inputs and outputs for quiet operation; and chassis/signal ground lift capabilities for quick hum isolation. The visionary design of the dbx 12 Series makes your job easier. The dbx 12 Series Equalizers were precision engineered to provide years of maintenance-free operation in any application. The magnetically isolated transformer, electronically balanced/unbalanced inputs and servo balanced/unbalanced outputs, RF-filtered inputs and outputs, and power-off hard-wire relay bypass with 2 second power up delay were steps our engineers took to ensure compatibility for all installations. Only the best components were utilized, yielding a 10Hz to 50kHz frequency response, greater than 90dB SNR (ref +4dBu), less than 0.005% THD +Noise (1kHz at +4dBu), and interchannel crosstalk of less than -80dB from 20Hz to 20kHz. All this attention to detail is contained in a 3U steel/aluminum chassis. SPECIFICATIONS:

PRICE WITHOUT V.A.T. BSS Opal FCS-966 Constant Q Graphic Eq Graphic equalisers 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 +/-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 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 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 FCS-966 are electronically balanced, with optional transformer balancing. To make installation of the FCS-966 easier, we'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.
