The Doepfer A-196 Eurorack Phase Locked Loop Module is a Eurorack phase locked loop module, which includes a voltage-controlled oscillator, a phase comparator and low pass filter. The module A-196 contains a so-called phase locked loop (PLL). A PLL consists of three parts: voltage-controlled oscillator (VCO), phase comparator (PC), and low-pass filter (LPF). All parts are normally connected to form a closed-loop frequency-feedback system. It has to be pointed out that the A-196 is a very experimental module and its functions cannot be described straight forward as for other modules. Rather the user should try out the possibilities by trial and error.

The main features of the Doepfer A-196 Eurorack Phase Locked Loop Module include:

• Phase locked loop
• Consists of: Voltage-controlled oscillator, a phase comparator, and a low-pass filter
• Applications: frequency multiplication; special sound effects; generation of clock signals for graphic VCO; (high speed VCO, e.g. for A-155 as graphic VCO); clocked audio delays or switched-capacitor filter.
• Width: 8 HP / 40.3 mm
• Depth: 40 mm (measured from the rear side of the front panel)
• Current: 40 mA
