Performance Eurorack Enclosure with Isolated Power and Utility Bus

The Make Noise 208 HP 7U 4 Zone CV Bus Case combines a heavy-duty travel enclosure with isolated multi-zone power distribution and integrated 1U signal utilities.

This case houses two 104 HP 3U rows for standard Eurorack modules alongside a dedicated 1U row featuring the Make Noise CV Bus. Instead of relying on a single shared power rail, its internal 4-Zone Power Board splits the +12V and -12V rails into four isolated power domains with independent ground returns. This isolation prevents power-hungry digital modules, displays, or high-draw processors from introducing unwanted background clock noise or bleed into sensitive analog audio paths.

In use, the case functions as a self-contained live performance station. The 1U CV Bus provides four color-coded signal mults with LED feedback, running across the width of the case so you can route master clock, pitch, or envelope voltages using short, clutter-free patch cables. The built-in 1U utility section also includes a dual-input Voltage Math circuit for summing and offset shifting, plus a balanced stereo output driver with an integrated AC-coupled limiter to protect headphones and PA gear from sudden voltage spikes.

The powder-coated metal shell features a removable lid with enough clearance to keep your system fully patched during transport. While the 2.5-inch maximum module depth easily accommodates modern surface-mount designs, ultra-deep vintage modules or unskiffable vintage power assemblies may require checking clearance before installation.
