Wolff Audio ProPatch 128R 128-Point Digitally Controlled Analog Patchbay (64 in / 64 out)

At the heart of every ProPatch is Wolff Audio’s proprietary relay based, software controlled switching architecture. A patchbay’s role is to route signals without affecting them—a purely passive connection. ProPatch contains no buffers, amplifiers, or active electronics in the signal path. None. Active circuitry, by definition, alters how connected gear interacts: introducing noise, affecting impedance, shifting frequency response, and potentially disrupting 48V phantom power. ProPatch’s relay based passive signal path delivers direct, balanced routing with no coloration, no interference, and no compromise.

ProPatch signal chains are configured and managed using an app that supports Windows, Mac or iPad OS. The app provides easy to use creation of complex device chains, including mults, mono to stereo, inserts, processors, AB groups and many more intuitive and useful shortcuts. All of these can be saved, recalled and associated with sessions.
