64 in/64 out. 1U Rack Space. 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. Using relay switching has many advantages. It is ultra-reliable, based on telecom-scale technology rated for millions of cycles. It requires little power to operate and generates no heat, eliminating the need for a fan. Because the signal path is "just a wire," it can pass full bandwidth audio signal, mic level, phantom power, control voltage, digital audio and MIDI. It is agnostic to the signals being routed. The relays are latching, so if a ProPatch loses power, the current routing remains in effect. The soft click of a physical relay cues that routing changes have happened. Connect the web enabled app to ProPatch via USB-C or Ethernet. Use the app to setup or adjust current routings or to configure and store new presets. The last configuration will load immediately on power-up. Use these to integrate ProPatch into an existing TT patchbay system, quickly connect temporary gear, or scale up and create a larger system by interconnecting multiple ProPatch units. Eliminate the usual workflow pause experienced when configuring manual patch bay systems and keep projects in the groove and flowing with ProPatch.
