The A-110-4 is Doepfer’s take on a thru-zero quadrature VCO that utilizes an extremely purse sine/cosine core, meaning there will be minimal distortion and no overtones compared to non-thru-zero oscillators. The module features two outputs, each 180 degrees out of phase with the other, and exponential and linear FM capabilities.
