Doepfer’s A-110-2 is a smaller, reduced version of the A-110-1 VCO. Unlike its predecessor, the module does not have a sine wave out, and features a toggle switch for its octave control rather than a rotary switch. However, the module features additional linear FM and soft sync inputs. Additionally, there is a jumper that determines the tuning range, from 1/2 octave to 4 octaves.  

• Low cost VCO
• Saw, Square (with variable pulse width), and Triangle waveshape outputs
• Hard sync and soft sync inputs
• Linear and Exponential FM inputs
• Three position octave switch
• Pulse width modulation input
