| The RS20 incorporates a high quality AC-coupled ring modulator that sounds somewhat different to the RMs in synthesisers such as the ARP2600, Roland System 100M, and EMS VCS3. This is because these three instruments (and many others) use the same ring modulator chip: the LM1496. The RS20 is an altogether different design that offers accurate ring modulation over a wider range of frequencies and amplitudes. It offers two inputs and one output. There are no controls.

X-IN Accepts any signal with maximum amplitude ±10V.
Accepts any signal with maximum amplitude ±10V.
Outputs the results of AC-coupled ring modulation. The new signal will have a maximum amplitude of ±10V.
The RS20 also incorporates a passive "multiple" with four interconnected input/output sockets. These are hard-wired together and may be used to distribute any audio signal or CV to multiple destinations. This multiple may be used as a simple mixer with unity gain.
