Doepfer A-110-1

Standard VCO for Modular System A-100Module A-110-1 (VCO) is a voltage controlled oscillator. The A-110-1 produces frequencies in a range of about 8 octaves, of which four waveforms are available simultaneously: pulse, sawtooth, triangle and sine wave.

The frequency of the VCO is determined by the position of the range switch and tune controller and the control voltages at the CV inputs. Thus, the VCO provides the possibility of frequency modulation. You can set the footage (octave of the fundamental) with the selector switch. The Tune control is used to fine tune the VCO frequency.

In the pulse wave the pulse width can be adjusted manually or by voltage control or modulated (PWM).

  • Depth: 55 mm (measured from the rear of the front panel)
  • Power requirements: +90 mA (+12V)/ -20 mA (-12V)

Doepfer A-110 Standard VCO
Blair, 03.11.2013
When I first became interested in modular synthesis I bought one of these, and liked it so much I bought another! The A-110 is probably the cheapest vco available, but delivers a decent audio performance, and offers a wide sound palette. It is saw-wave based, and offers another three wave shapes: sine , pulse and triangle. CV baed modulation of frequency and pulse width is available. According to the manual, the sine and triangle waveforms are not true, but derived from the saw wave. In practice all the waveforms sounded good to me. A pair of A-110's track very well together, and deliver good hard sync and FM results.

Other things I liked about the A-110:
* it was well calibrated on delivery and it achieves stable tuning within 5 minutes.
* At 10HP it is perhaps wider than it needs to be, but the control knobs are easy to use.

Room for improvement:
* The fine tuning range is not enough to tune one A-110 a musical interval above another vco, for instance a 4th or a 5th. I understand that there is a modification that can be made to the circuit board, but I feel the module should come set up this way.
* The A-110 cycles down to 15hz, which is not quite low enough to act as an LFO.

However, for the price this VCO is an absolute bargain. I bought the A-110 as a 'starter' vco, thinking I would sell or trade it when I could afford a more expensive vco. Instead I kept it, and bought another.

A bit dull
omz , 16.01.2020
Perhaps to reinforce its marketing as a "basic VCO", it sounds quite dull: only the square wave has some character.
Triangle and saw wave sound pretty dull.
Regarding the hardware: the construction and interface feels solid overall, but the jack sockets feel low quality and poorly machined.
Overall, I don't know whether to recommend it, even to beginners. Consider instead investing a bit more in a more versatile module.

The old one's are the best
Wayne M., 01.09.2013
The A-110 is still the staple VCO of many modular synths. A tried and tested design that never ceases to impress. Ideal for first timers too!
