Rack Plumber HD 1U

Patch-cable extension system

RackPlumber HD is a passive patch-cable extension system designed for moving signals cleanly between distant or multi-case Eurorack setups.
It provides 17 mono TS channels plus one stereo TRS channel that can carry MIDI, headphones, or any other TRS-based signal.

Two RackPlumber HD modules connect with a single HDMI cable (up to 2 meters), creating a simple and reliable way to link large or spread-out cases without extra cable clutter.

RackPlumber HD requires no power. It passes CV, Gate, audio, and MIDI (via the stereo channel) in either direction.
Each jack includes an internal LED that shows activity when nothing is patched; the LED is automatically bypassed when a cable is inserted, ensuring no signal drop.

Every RackPlumber HD includes two HDMI ports:
• A front-panel connector for linking two cases
• A rear connector for internal shortcuts inside a large rack

Multiple RackPlumber HD units can be chained (front of one to the back of another) to create passive mults. A rear jumper lets you disable the LEDs when using chained configurations.

HDMI cables are not included by default; you can add a 1.5m or 2m cable using the order options.

Jack LED colors may vary.

RackPlumber HD is available in two formats: a 3U version (6HP) or a 1U Intellijel-compatible version (26HP).
