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.
These merchants probably sell this module. Huh?
