The RS110 consists of a two channel audio mixer followed by four, parallel, resonant filters with voltage controlled frequency and a unique "insert" point in the feedback path that generates and controls resonance.
The RS110 offers four filter modes. These are 24dB/oct low-pass, 24dB/oct high-pass, 12dB/oct band-pass and 12dB/oct band reject (often called 'notch') filtering, with the cutoff frequencies (Fc) of the high-pass and low-pass outputs being the centre frequencies of the band-pass and notch outputs. Each of these filter characteristics is described in appendix 2.
There is no switch to select between the modes because all four are available simultaneously from the appropriate output sockets. However, the cut-off and resonance can not be defined individually for each, and the controls act upon each mode equally.
Usage with eurorack: Analogue Systems modules include their own custom ribbon connector that differ from the standard Doepfer ribbon connector. Many Eurorack cases include two types of power sockets (Doepfer and Analogue Systems type) for connecting modules. Please check that your case has compatible Analogue Systems sockets or please inquire about purchasing a converter cable from us. We are here to assist you with any questions you might have on connecting these modules but are not responsible for modules that are improperly installed. Please be sure to understand the connectors before purchasing.
