ADDAC701 – Voltage Controlled Oscillator


Out of stock

SKU: ADDAC_.701 Maker:


The ADDAC701 is a fully analog Voltage Controlled Oscillator. It works at both the audio and sub-audio ranges (0.01 to 40.000 Hz), with four simultaneous waveform outputs (rectangular, sawtooth, triangle and sine).

Choose your octave and tune the frequency using several scaling options, including a dedicated CV input for microtuning.
The rectangular wave has two dedicated mixable CV inputs that control pulse width, to create incredibly dynamic timbres.

On the auxiliary output you can switch on any waveform, with straight or inverted outputs. A linear input allows you to control the frequency linearly, essential for operations like frequency modulation, with a dedicated knob for attenuation.

The ADDAC701 includes internal compensation for room temperature, so that your oscillations are always in tune, no matter where you are.
