Analogue Systems RS-100S LPF Mk3 (Dual Bus)


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.


The Dual Bus version of the RS-100s features two power connectors, meaning it can be directly connected to either an Analog Systems or a Doepfer modular system. – Adapters are no longer necessary.

Because of the different position of the mounting holes there will be a gap of 0.5HP (= 2.5 mm) when mounting an Analogue Systems module next to a Eurorack module. Take this into consideration when planning your system. Gaps can be covered with 1.5HP wide blank panels by Doepfer.


Two audio inputs with level controls. One audio output.
Two cutoff CV inputs: one with fixed 1V/octave, the other is variable


3U module in Analogue Systems form factor, 12HP wide, 64mm deep
30mA power consumption
