Wolff Audio ProPatch 128R

The Wolff Audio ProPatch 128 R is a cutting-edge, software-controlled analog patch bay designed to streamline audio routing with precision and ease. This relay-based system delivers straight-wire performance, ensuring a clean and transparent signal path free from distortion, noise, or unwanted coloration. Unlike traditional patch bays, ProPatch eliminates the need for manual patching, offering any-to-any routing via an intuitive web app that is compatible with Windows, Mac, and iPadOS. Users can create, store, and instantly recall unlimited presets, including stereo pairs, immersive audio configurations, and control voltage routes for keys, synthesizers, or effects pedals.

With 128 patch points (64x64 I/O) and 48 channels of DB25 connectivity, ProPatch offers a high-density solution in a 1RU compact chassis. The front panel includes 16 TT pairs, 4 XLR/TRS combo jacks, and 4 TRS connectors, making it easy to integrate temporary gear or expand the system with additional units. The USB-C-powered device operates without fans, maintaining a silent studio environment. ProPatch automatically loads the last used preset on power-up, and its relay-based switching provides immediate, tactile confirmation of routing changes. Whether for professional studios, live sound setups, or complex audio workflows, ProPatch eliminates workflow interruptions and ensures seamless audio management with zero compromises on sound quality.
