RS-100S

Low Pass Filter Mk3

This low pass filter is a very good -24dB/octave Moog filter, based on the classic Moog cascade with selected, low-noise transistors.

Being the successor of the RS-100, the new "S" version features several improvements regarding stability, tracking, distortion behavoiur and also the frequency range.

24dB/oct low pass filter based on the design by Moog. Two signal inputs, resonance, manually and voltage controlled cutoff frewquency. Frequency range 10Hz to 35kHz with CVs applied. The transistors used in the filter cascade are low-noise, have been selected ans in addition matched in pairs what improves frequenc response over the whole frequency range. A better stability guarantees after one minute heating time that the flter can be used as a clean and well tracking sine wave oscillator.
