8 Octave Fixed Filter Bank

The RS210 is based on a filter bank originally designed in the 1970s for inclusion in the ultra-rare EMS
Synthi 100 Mk2. (Only one of those instruments was ever built.) It operates in a relatively low frequency
range and has gentle (low 'Q') filters that are ideal for overall shaping of the sound.

IN USE

The RS210 incorporates eight static filters with centre frequencies of 75Hz, 150Hz, 500Hz, 700Hz, 1.5kHz,
3kHz and 7kHz, and the eight knobs on the front panel are gain controls that allow you to affect the
amplitude of the signal in each band.
With its knob below '5' on the marked scale, a filter will attenuate the signal. Due to the low Q, the
maximum attenuation in the band is heavily dependent upon the positions of the knobs in adjacent
bands.
If a knob is in its fully clockwise position (MAX) the gain in that band is approximately +2.5dB.

IN
The input accepts audio signals and CVs in the range +/-10V.

OUT
The RS210 outputs signals and CVs in the range +/-10V.
Note: If a !10V signal is presented to the input of the RS210 and
further boosted, distortion will occur
