A-196 Phase Locked Loop (PLL)

Doepfer A-196 Phase Locked Loop (PLL): Experimental Frequency Tracking and Modulation

The Doepfer A-196 is a unique Phase Locked Loop module designed to track and lock onto external frequencies using an XOR phase comparator, low-pass filter, and internal VCO. It’s capable of creating wild, unpredictable modulations and synchronized audio effects — ideal for adventurous sound design.

Key Features:

• Built-in PLL circuit with XOR comparator, filter, and VCO

• Syncs internal oscillator to external frequency input

• Produces chaotic, glitchy, or harmonically rich modulation

• CV-controllable parameters for full patching flexibility

• Perfect for experimental, noise, and feedback-based patches

Technical Specifications:

• Width: 12 HP / Depth: 55 mm

• Power Consumption: +12V: 40 mA / -12V: 20 mA

• Weight: Approx. 150g

A powerful modulation and sync tool for creative modular musicians.
