RS-180N

VCA with logarithmic and linear inputs

Classic, high quality VCA module with logarithmic and linear control inputs. This way the module is suitable to control audio signals as well as CVs.

Thanks to a new front panel and bus concept, this version of the RS-180 is fully compatible to Doepfer-style Eurorack systems.

With the "initial level" control you can open the VCA manually which is handy if the modulation signal is bipolar: e.g. when doing a tremolo with a sine wave LFO. Two CV inputs with attenuators are available: The linear one is better when you want to control CV signals or if the modulation signal is a slow LFO. The logarithmic input is more akin to human hearing and recommended when you want to control audio signals and a "natural" response from the envelope.

Two signal inputs make an mixer module obsolete in many cases.
