DoepferA-110-4 Thru Zero Quadrature VCO

Doepfer A-110-4

The A-110-4 is Doepfer’s take on a thru-zero quadrature VCO that utilizes an extremely purse sine/cosine core to ensure minimal distortion and the absence of overtones. Its "quadrature" designation means that the oscillator outputs sine and cosine waveforms simultaneously. Consequently, the module features two outputs, each 90 degrees out of phase with the other, as well as exponential and linear FM capabilities.
