ADDAC ADDAC200PI (????)
Two channels of pedal integration squeezed into 4 HP — tiny footprint, big utility, and a cult favorite for modular players who route effects like clockwork.
Overview
The ADDAC200PI Pedal Integrator isn’t flashy, but if you’ve ever tried to wedge a stompbox into a Eurorack rig and cursed the impedance mismatch, this little module is the quiet hero you didn’t know you needed. Made by ADDAC System, it’s a compact two-channel FX send/return solution designed specifically for integrating guitar pedals into modular setups — a real-world problem that a lot of boutique modules pretend doesn’t exist. It’s not a filter, not an oscillator, not even a sequencer; it’s infrastructure. And sometimes, the most boring modules are the ones that stay on your case the longest.
What it does is straightforward: each of its two channels handles send and return duties, with the send side attenuating the typically hot modular output down to instrument level — that sweet spot where your Tube Screamer or reverb pedal won’t clip into oblivion. Then it brings the effected signal back in safely, ready to be mixed or processed further. No buffering drama, no ground loops (in theory), just clean, functional signal routing. And it does all this in just 4 HP, which in Eurorack real estate is basically free space. That kind of efficiency is why owners report it being a staple in compact or travel cases, where every millimeter counts and every function needs to pull double duty.
It’s part of the ADDAC200 Series, a family of utilitarian modules that includes multiples, rail monitors, and other behind-the-scenes workhorses. The 200PI stands out not for complexity, but for solving a niche problem elegantly. It’s not the kind of module you demo on YouTube with sweeping filter sweeps — it’s the one you forget is there until you unplug it and suddenly your delay pedal sounds like garbage. That’s the hallmark of good utility gear: invisibility through reliability.

Key Features
Dual-Channel Send/Return with Level Matching
The core of the ADDAC200PI’s design is its ability to handle two channels of send and return — with proper level attenuation on the output side. Modular synths run hot, often peaking at ±12V, while guitar pedals expect instrument-level signals (around 1V). Without attenuation, you’re feeding your vintage Analog Man a signal it was never meant to handle, leading to distortion, compression, or outright malfunction. The 200PI’s send channels step that down cleanly, so your pedals behave as intended. Then it accepts the return signal without further coloration, preserving the pedal’s character.
Flexible Jacking for Mixed Setups
Each channel features both 3.5 mm (eighth inch) and 6.3 mm (quarter inch) jacks for send and return. That might seem like a small detail, but in practice, it’s huge. Eurorack uses 3.5 mm as standard, Most integrators force you into adapter hell or double-cable setups. The 200PI eliminates that — you can patch your modular outputs directly with 3.5 mm cables and connect your pedals with standard quarter-inch cables, all without dongles or breakout boxes. It’s a physical design win that reflects actual user workflows, not just electrical schematics.
Minimal Footprint, Maximum Utility
At 4 HP wide and only 30 mm deep, the 200PI is built for tight systems. It draws just 10 mA on both +12V and -12V rails, with no 5V draw, making it easy to power even on crowded cases. It’s not a processor — it’s a translator, letting two different audio worlds talk without shouting over each other.
Collectibility & Value
While no current market prices or common failure modes have been documented, the ADDAC200PI is frequently mentioned among ADDAC System’s most popular products. Users appreciate it as a cost-effective solution that efficiently handles full stereo signals in modular environments. One owner on Equipboard called it “one of the best eurorack…” modules, trailing off as if the praise was too obvious to finish. Given its MSRP of $134 and a DIY kit option priced at 64€ (excluding VAT), it was clearly positioned as an accessible utility module from the start. Whether bought assembled or built from a kit, it’s the kind of module that tends to stay in cases once installed — not because it’s rare, but because it’s useful. That kind of quiet indispensability often translates to steady demand, even if it never becomes a “holy grail” item.
