Module Description:
This module is a modern, refined take on the classic 1973 Serge Dual Processor (PRC), originally created by Serge Tcherepnin. As described in the original SMMS catalog:

“The Dual Processor (PRC) consists of two independent circuits for adding and inverting control voltages. It provides full control over the level and polarity of three input voltages, along with a manually adjustable offset that can be added to the mix.”

In this updated version, a compression/saturation circuit has been added to the bottom processor, introducing rich, nonlinear shaping—from subtle soft-clipping to pronounced wave distortion. This enhancement significantly broadens the module's utility, making it equally powerful for control voltage (CV) processing and creative audio manipulation. The entire circuit is DC-coupled, ensuring reliable performance across a wide range of modular applications.

Features:

  • Top Processor:
    – Switchable ±5V offset on output

  • Bottom Processor:
    – ±5V offset
    – Compression/Saturation switch for additional wave shaping

  • Each Processor Includes:
    – Three attenuated inputs, each with on/off/invert toggle switches

From the original SMMS Catalog:
”The DUAL PROCESSOR (PRC) is two independent circuits for adding and inverting control voltages. Full processing control of level and polarity of three inputs voltages Is provided. A manual offset voltage can be set to be added to the other three inputs.”


** 4U Modular is a term used for the format most commonly known as “Serge Format” or “Loudest Warning Format”. Out of respect for the ever growing format, 4U Modular is the easiest way to refer to it. More Specifically it refers to the panel height and mounting hole style. 4U Modular will patch up just fine with other 4U "Serge" formats such as "Random Source", but it will not mount in RS boats or Buchla Boats (or power off Buchla power for that matter). An info page about this will be added to the website soon to make this a lot more easy to understand.
