Product Description

Relay based. Pristine signal path. Zero compromise.

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.

Rear panel DB25 connectors provide 48 channels of I/O, while front panel I/O includes 16 TT I/O pairs, 4 XLR/TRS combo jacks and 4 TRS jacks. 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.

The ProPatch takes up a single rack space, does not generate heat, nor does it require fans. Designed to easily 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.
