Eurorack case 18U/126HP Performer Series Pro


This professional handmade 18U/126HP Performer Series Eurorack modular synthesizer case is the biggest case in our product line.
As it’s successor, the 12U/104HP Performer Series Pro, this 18U/126HP case uses the same detachable middle “ring” that acts as a spacer enabling the case to remain patched while closed yet keeping the modules flush-mounted when open. Even better, this ring also functions as a rock-solid stand for the top section holding it at the perfect angle for performance. 

Due to it’s big size and weight when completely filled, this case is not be advised as a travel case. Most artists use this case in their studio’s, and we believe that’s what it’s  best for.

A separate 9U lid, is available as well. This way you can use for example one halve of the 9U case and carry it fully patched  to a gig.

Starting with reliability in mind we build our cases with Penn Elcom components for maximum durability and apply a two-component coating solution that adds an extra layer of protection to your serious investment. We want to make sure your gear is working great in the studio or at a live event.

Power Supply 

MDLR PWR powered busboard 85W version.

MDLR PWR is a high precision low noise and high power bus board for your eurorack modular systems.  With a total of 40 headers you’ll never run out of connectivity, so all your lovely modules can be easily connected.

Due to super easy installation (it’s only about connecting two cables) this MDLR PWR  PSU solution is perfect for use in DIY projects as well. 

By using an external PSU adapter there is no risk of high voltages inside your eurorack case.

MDLR PWR is fully protected on the input as well on the output to ensure maximum security.
