ADDAC System ADDAC200 (Dates Unconfirmed)

Two HP of pure signal plumbing—small, silent, and essential for the modular pack rat.

Overview

The ADDAC200 2HP Multiples is one of those modules you don’t think about until you’re elbow-deep in cables and realize you’re one split short of making a patch work. Made by ADDAC System, it’s a Eurorack module designed for one job: duplicating control or audio signals across multiple destinations. No knobs, no switches, no blinking lights— It lives in the background like a stagehand, but try running a show without it and you’ll feel the absence fast.

The module’s utility is its selling point. It doesn’t do anything flashy, but in a system built on patching and rerouting, having reliable multiples is like having extra hands. You’ll find them next to sequencers needing to fan out clock signals, or near envelope generators feeding multiple VCAs. It’s the kind of module you buy not because it’s exciting, but because your rack would fall apart without it.

Collectibility & Value

The ADDAC200 is currently offered with a black front panel as standard, though custom-colored panels are available directly from ADDAC System. These color options add a touch of personalization to an otherwise utilitarian module, letting builders match or accent their rack’s aesthetic. However, no original pricing, production years, or current market values were found in available sources. Given its role as a utility module, it’s unlikely to become a collector’s item in the traditional sense—nobody’s hoarding multiples like rare VCOs—but well-maintained units with custom finishes may carry slight premium appeal among boutique rack builders.

For now, it remains a functional piece, valued for its space efficiency and clean integration rather than rarity or vintage status.
