1. Voltage controlled LFO with two selectable frequency ranges: LOW goes from 0.3Hz to 6Hz and HIGH from 5Hz to 1.500Hz; using control voltages you can reach lower and higher frequencies, though. The CV input is not compliant to the 1V/octave characteristic. Two waveforms are available; square and triangle.
2. analog noise generator that produces white noise
3. Sample & Hold: due to normalized sockets you can use this sub-module without patching as the LFO´s square wave and the white noise are pre-patched. Alternatively you can insert other signals than the internal white noise through the Source In socket.
4. VCA: classic VCA with one signal input, two signal outputs and one CV input

The Dual Bus version of the RS-380 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.
