Doepfer’s A-196 Phase Locked Loop module consist of three sections. The first is a VCO with a three position switch for selecting the tracking range. The second is a Phase Comparator with a three position switch between different comparator types that leads to distinctly different timbral characteristics. Finally, the module features a low-pass filter normalled to the output of the Phase Comparator.
Three position range switch for VCO tracking range
Offset knob for offsetting the range of the VCO
Square wave output normalled to the input of the Phase Comparator
Three position switch between phase comparator types - different timbral qualities
Input 1 is the waveform that locks to the Input 2 waveform
LED indication for locking type
Dedicated Low Pass Filter, normalled to the output of the phase comparator
