Dual Mode Graphic EQ

BSS Audio

FCS-960

In most sound systems, the graphic equaliser is an essential element in sweetening and response contouring a system or program channel, or tuning out room resonances or onstage feedback. Of the units available, many are only suited to one function or the other. In the BSS FCS-960 you have an equaliser which is ideally suited to either task through front-panel filter WIDTH switching, allowing you the option to select between smooth or fine control characteristics which have been carefully optimised for each application. The same unit may be used throughout an installation, making it interchange trouble-free, and ensuring operator familiarity. Many conventional equalisers using a gyrator filter design produce undesirable contours and colourations when adjacent filters are boosted or cut together, producing a response which affects the overall sound, in some cases dramatically. BSSs design, using a MFB constant-Q topology, results in a smooth contour in such situations, producing a response that you would expect from combined filters, and a sound that is free from non-musical colourations. Long travel 45mm faders provide accurate control resolution while the constant-Q filters ensure consistent selectivity at any fader setting. Faders are positioned on the 30 standard 1/3 octave ISO centres from 25Hz to 20kHz and have centre detents with filter by-pass for absolute zero accuracy. This also means that you have the reassurance that if a filter is not being used, it is absent from the signal path. For touring systems use, the dual channel FCS-960 is already hugely popular. In just 3U of rack space (5.25"), the FCS-960 provides two channels of 30 band equalisation, each channel independently switchable to operate with normal or fine filter widths. Patching the two channels in series combines the options, allowing you to apply smooth or fine boosts or cuts at any isocentre frequency. PA companies and Artistes around the world specify the FCS-960 Dual Equaliser for all acts, major and support, and the same model is being installed in major entertainment venues such as Theatres and Performing Arts Centres. In fixed installations, the FCS-960, with its choice of filter bandwidths, means that youll never be compromising on the use to which you put the equaliser. The FCS-960 is ideally suited for installations in Conference Centres, Performing Arts Centres, Airport PA systems, Hotels, Houses of Worship, Discotheques, and many other such installations.

TECHNICAL SPECIFICATIONS Both inputs and outputs on the FCS-960 are fully balanced as standard, with the outputs floating, and use standard XLRtype 3-pin connectors. Transformers are available as options, should isolation be required. One common problem with graphic equalisers is the inability to view the fader positions accurately from various operating positions and under low-light conditions. BSS has produced a custom-designed control knob with ribbed edges which is highly visible under extreme conditions, and virtually eliminates parallax errors. Signal headroom indication is provided by a peak clip led which monitors a number of points within the circuitry, indicating signal levels within 2dB of clip at any of those points. Since its release the FCS-960 has steadily increased in popularity to become an industry standard. Combining all the required features with a superlative sonic performance has meant that the FCS-960 is now demanded by discerning engineers all over the world. Input Section IMPEDANCE MAX.
