Wolff Audio ProPatch 128R 64-in/64-out Digitally-Controlled Analog Patch Bay

The Wolff Audio ProPatch 128R is the next generation software-controlled, analog patch bay. The number one job of a patch bay is to route audio with 100% transparency. To accomplish this, ProPatch uses a matrix of relays (a LOT of them). No FET switches, no games with gain staging, no electronics in the signal path, no compromises. Routing in ProPatch has zero effect on your audio signals because the path is effectively a "straight wire".

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. Connect your audio processors like plug-ins. Drag and drop your devices into complex audio chains that can be edited, auditioned and recalled instantly.

RELAY SWITCHING

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, Ethernet or WiFi. 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 combi jacks and 4 TRS jacks. Use these to integrate ProPatch into an existing TT patch bay 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.

SOFTWARE-CONTROLLED ANALOG PATCH BAY

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 patch bay, the ProPatch may also be integrated with large existing TT patch bay systems via its front panel TT connections. Multiple ProPatches can be chained together to incorporate larger routing systems.
