ADDAC System 200B (2023–)

A no-frills buffered mult that does one job well. Patch it wrong and your whole system can go silent.

Overview

The ADDAC System 200B doesn't make sound, shape waveforms, or generate chaos. It splits signals cleanly and reliably - no crosstalk, no loading down your oscillators, no voltage drops that make your sequencer stutter. Patch in a quantizer, a clock divider, or a master LFO, and you can send that signal to six different modules - filters, VCAs, envelope followers - and each one gets the full-strength, uncolored voltage it needs. That's the whole trick: transparency. No coloration, no surprises.

The 200B is part of ADDAC's 200 Series, compact utility modules designed for the builder who values function, build quality, and skiff-friendliness. At 4HP, it's barely wider than a banana plug, and at 40mm deep, it fits even the shallowest cases. The front panel is clean: six jacks in two groups of three, each group sharing a single input. No LEDs, no switches, no trim pots. Just two buffered multiples, each splitting one input to three identical outputs. You install it early and forget about it, until you try to live without it and your clock signals, gates and modulation CVs stop holding up across complex patches.

Key Features

Two Independent Buffered Multiples

The 200B gives you two completely isolated buffered mult sections, each with one input and three outputs. This isn't a passive mult, where splitting a signal can load down the source and cause voltage droop, especially with high-impedance or precision CV signals. Each input feeds a discrete transistor buffer that actively drives the three outputs. So your 5V clock pulse stays 5V across all three outputs, even if you're feeding slow, high-impedance modules like analog logic gates or vintage-style sample-and-holds. That makes it a good fit for distributing timing signals, pitch CVs, or modulation sources that need to stay stable across multiple destinations. Passive mults might save a few milliamps, but they can cost you in subtle ways: slightly mistimed triggers, drifting pitch, or flaky sequencing.

Skiff-Optimized Design

ADDAC built the 200B for real-world use, not just to save panel space. The 4HP width fits between wider modules without wasting rack space, and the 40mm depth clears almost every skiff and travel case on the market. The jacks are spaced for easy patching, even with thick cables, and the recessed mounting screws won't snag your patch cords. The front panel uses ADDAC's minimalist look: white silk-screen on black anodized aluminum, with clear labeling and no clutter.

Historical Context

The 200B arrived in 2023, as Eurorack was shifting away from "hero modules" and toward system design. For years, the format was dominated by flashy oscillators, complex sequencers, and modules that promised to "unlock new sonic dimensions." As racks grew more complex, builders needed infrastructure: clean power distribution, reliable clock management, and signal buffering that didn't color or degrade CVs. ADDAC, a Lisbon-based builder known for blending analog warmth with digital precision, responded with the 200 Series, a family of utility modules that included the 200A (current ammeter), 200PI (pedal integrator), and 200B. These weren't meant to be the stars of the patch. They were the stagehands. While other manufacturers offered buffered mults in 6HP or 8HP formats, ADDAC squeezed the functionality into 4HP without sacrificing performance. It wasn't the first buffered mult on the market, but it was one of the most efficient.

Collectibility & Value

The 200B isn't a collector's item, at least not yet. It's a modern utility module with no limited runs, no exotic components, and no cult following. That ordinariness suits a long-term spot in a touring or studio rack. Units from 2023-2024 sell for $100 - $130 new, depending on region and distributor. Used prices hover around $70 - $90, with little fluctuation. Failures are rare, but service technicians note that the most common issue is jack damage from over-tightening or repeated plugging, especially in live setups. The discrete transistor buffers are sturdy, but the module draws a relatively high 60mA total (30mA per rail), so users with tightly packed cases should account for that in their power planning. There are no known firmware updates or revisions, and no widespread reliability concerns. If you're buying used, check that all six outputs pass signal and that there's no crosstalk between the two sections.
