| The RS110 is a true analogue multimode filter. It is built from discrete components, and it eschews the use of the filter chips used by other manufacturers of analogue synthesisers. This means that the RS110 has a unique character.
The cut-off frequency control Fc from 30Hz to +15kHz. Fc can also be controlled using one or both of the CV inputs.
The filters have a common resonance, 'Q', that can be controlled using the RESONANCE knob from zero, (no emphasis of the signal at Fc) to self oscillation, even in the absence of an input. Each mode will now produce a stable tone at the cutoff frequency determined by the various controls. This oscillation takes the form of (approximately) a sine wave, and it is produced by all four of the conventional audio outputs. The exact nature of the wave varies slightly from mode to mode, and you can use these subtle differences to create tonal variation when using the RS110 as an oscillator.

2 channel audio mixer
, 4parallel, resonant filters with voltage controlled frequency
"insert" point in the feedback path that generates and controls resonance.
4 filter modes.
12dB/oct. The RESONANCE control then acts as a LEVEL control for the tapped signal.
RES OUT & RES IN include the introduction of voltage controlled resonance (achieved by routing the signal via an RS180 VCA) or the creation of special effects (achieved by modifying the signal using devices such as reverb units).
2 inputs: SIG 1 IN and SIG 2 IN, each with an associated LEVEL control.
The inputs accept signals in the range ±10V,
these signals are mixed so that they can be filtered simultaneously.
4 outputs, one for each mode, and these each carry a signal in the range ±10v.
