Wolff Audio, a leader in professional audio equipment design, has released the ProPatch — the first digitally-controlled, entirely relay-based, large-scale analog patchbay. At its core, the ProPatch 128R is a 128-point, 64-in/64-out patchbay with flexible any-to-any routing — but calling it just a patchbay would be an understatement. It is a paradigm shift in studio workflow: treating hardware outboard gear the way a DAW treats plug-ins — configurable, recallable, and instantly deployable — while maintaining an absolutely pristine, electronics-free signal path.

Key elements of its design:

• 100% Relay-Based Signal Path The ProPatch 128R is entirely relay-based, ensuring straight-wire performance with zero electronics in its fully balanced internal signal path. This means it passes full-bandwidth signals without noise, crosstalk, or distortion. The relays are based on telecom-scale technology rated for millions of cycles, require little power to operate, and generate no heat — eliminating the need for a cooling fan.
• Universal Signal Compatibility The architecture delivers 0% added distortion and noise across a bandwidth extending from DC to the limits of test equipment, while safely passing mic-level audio (including 48 V phantom power), line-level signals, control voltage, MIDI, digital audio, and timecode. Switching is instant, alleviating phantom power short issues.
• Software-Controlled Routing via Wolff Hound App The ProPatch 128R allows you to configure and manage routing presets effortlessly using an intuitive software application. This app lets you deploy your outboard processors like plug-ins — drag and drop them into complex chains, and audition, edit, and recall your presets instantly. The control application runs on Mac, Windows, and mobile, and can be associated with DAW sessions. The unit connects via USB-C, Ethernet, or WiFi.
• Non-Volatile Latching Relays The relays are latching, so if the unit loses power, your current routing remains intact. The last used ProPatch configuration is non-volatile and auto-loads on power-up.
• A/B Comparison & Advanced Routing Tools Additional tools include easily saving and recalling snapshots, signal chains, sophisticated multing, expansive routing possibilities, and the creation of "A/B groups" for gear comparison. Engineers can audition alternate devices and processing paths with a single click.
• High-Density Connectivity in 1U The rear panel provides high-density DB25 connectivity for 48 channels of I/O, while the front panel adds 16 TT I/O pairs, 4 XLR/TRS combo jacks, and 4 TRS ¼" jacks for integrating existing TT systems, quickly patching guest gear, or expanding larger ProPatch-based networks. This gives the ProPatch the highest channel density per rack unit of any patchbay — traditional or automated.
