The 7U Performance Case with TPS80 power (Black), from Intellijel Designs, is a sturdy and ergonomically efficient case specifically designed to house Eurorack modules. Constructed from alluminum and powered by TPS80 power, the case is ideal for transporting one\'s Eurorack modular synthesizer system. One of the most useful features of this case are the audio and MIDI jacks on the back: there are four audio jacks, MIDI in/out/thru, and a USB jack, all of which can be connected to specific Intellijel 1u modules for enhanced functionality.
