ES20 - 1973 VCO
Let's Go Shopping

The ES20 starts with a classic sawtooth oscillator core and adds a voltage controlled wave shaper to the output.

Unlike most conventional VCOs' the ES20 does not have a 1V/Octave input. However the scalable input of the ES20 can be used in conjunction with the FREQUENCY control to provide tonal tracking.

The CV-B knob can be used as a FINE TUNE control for the oscillator.

The wave shaper allows the [SHAPED] output to swing from a sine wave to a modified sawtooth output and can be both manually and voltage controlled.

Frequency Range:
16Hz - >16kHz
SAW Output:
5V pk-pk
SHAPED Output:
3V pk-pk
