The ProPatch supports USB-C, Ethernet or WiFi connectivity.

128 patch points are available as 12 rear panel DB25s, 16 TT I/O pairs on the front panel, 4 XLR/TRS combo jacks and 4 TRS jacks. The ProPatch takes up a single rack space, does not generate heat and does not require fans. Designed to drop-in and replace an existing TT patchbay, the ProPatch may also be integrated with large existing TT patchbay systems via its front panel TT connections. Multiple ProPatches can be chained together to incorporate larger routing systems.

The ProPatch 128R is now available, with additional models set for release at NAMM 2025.
