RackPlumber HD: High-Density Patch Extension System
RackPlumber HD is a passive, high-capacity extension system designed to transport a large number of signals between distant or multi-case Eurorack setups. Using a single HDMI cable, you can bridge up to 18 channels simultaneously, keeping your workspace clean and organized.
⚠️ Important: A minimum of two modules (a pair) is required to create a connection. Units are now available individually to allow for custom configurations, mixing form factors (1U/3U), or expansion.
Customizable Setup: Mix & Match
You can now purchase individual units to build the exact bridge your system needs:
High-Density Connectivity: Each module provides 17 mono TS channels plus one stereo TRS channel (perfect for MIDI, headphones, or balanced signals).
Mix Form Factors: Connect a 1U module in one case to a 3U module in another.
Scale & Mult: Chain multiple units (front to back) to create a massive passive mult across your entire studio.

Key Features
Dual HDMI Connectivity: Features a front-panel port for inter-case patching and a rear port for "internal shortcuts" or permanent clean routing inside a large rack.
Bi-Directional Signal Path: Pass CV, Gate, Audio, and MIDI in either direction with zero latency.
Intelligent Monitoring: Internal Jack LEDs show signal activity. To ensure 100% signal integrity and zero voltage drop, the LEDs are automatically bypassed as soon as a patch cable is inserted.
