RS-215

Eight Octave Filterbank

The RS-215 is a modern filterbank with steeper filters than the RS-210, and which operate in a slightly higher range. It allows you to shape the sound more precisely than the RS-210.


Filterbank module with eight fixed filter frequencies, each one octave apart. It is the successor of the RS-210 which was based on a rare 70ies filter bank from EMS.

The newer version has different frequencies for a wider frequency range and the filters have a higher slope. The fixed frequencies are 100Hz, 200Hz, 400Hz, 800Hz, 1.6kHz, 3.2kHz, 6.4kHz and 12.8kHz

Each frequency has a dedicated control attenuating the according filter band. If only one control is turned all the way down, the frequency band will be attenuated -9dB.

If all filters are closed then the attenuation is infinite. At maximum position of the control the frequency band´s level is almost unity gain.

In use :

The RS-215 incorporates eight static filters with centre frequencies of 100Hz, 200Hz, 400Hz, 800Hz, 1.6kHz, 3.2kHz, 6.4kHz and 12kHz, 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 MAX, a filter will attenuate the signal. With just one knob at MIN the level in that band is reduced by approximately 9dB. With all knobs at MIN the signal attenuation approaches ∞dB.

If a knob is in its fully clockwise position (MAX) the gain in that band is approximately unity.

  • IN:

    The input accepts audio signals and CVs in the range ±10V.

     
  • OUT:

    The RS-215 outputs signals and CVs in the range ±10V.
