Analogue Systems RS-85 Extended VC-LFO


The Analogue systems RS-85 module is a voltage controlled LFO with four wave form outputs, reset and a very wide frequency range, up to audio frequencies so you can use the module as an auxilliary oscillator.



The LFO frequency is set with a potentiometer and/or a control voltage and is visualized by a LED. Three freqeuncy ranges are selectable:

  • very low: 0,005Hz - 1Hz
  • low: 0.02Hz - 5Hz
  • high: 3Hz - 1.4.kHz

four wave form outputs:

  • sine (±5V)
  • triangle (mit Pegelregler, ±5V)
  • square (mit Pegelregler, ±5V)
  • sawtootch (Bi-directional level control with center detent. Counterclockwise you set the level of a rising sawtooth, clockwise the level of the falling sawtooth)

The RS-85 has a reset socket for restarting the LFO.


Usage with Eurorack:
Analogue Systems' modules are designed solely for use in cases and cabinets made by Analogue Systems. Through the use of adaptors or adaptor cables, however, it is possible to connect them to Eurorack cases.
Should you chose to use an Analogue Systems module in an Eurorack case, please note that the warranties are thus void and the use occurs at your own risk! If the module is plugged in incorrectly and therefore damaged the customer has to bear any costs for repair and shipping!

Because of the different position of the mounting holes there will be a gap of 0.5HP (= 2.5 mm) when mounting an Analogue Systems module next to a Eurorack module. Take this into consideration when planning your system. Gaps can be covered with 1.5HP wide blank panels by Doepfer.


inputs: linear frequency CV, reset input
outputs: sine, triangle, square, sawtooth
