Wolff Audio ProPatch 200

ProPatch Relay-Controlled Patchbay

ProPatch is built around Wolff Audio’s proprietary relay-based switching architecture, delivering truly passive, straight-wire signal routing. There are no buffers, amplifiers, or active electronics in the signal path, preserving impedance, bandwidth, noise performance, and phantom power integrity. The result is direct, balanced routing with no coloration or interaction artifacts.

Routing and signal chains are configured via a dedicated app for Windows, Mac, and iPad OS. Complex setups including mults, mono-to-stereo paths, inserts, processors, and AB comparisons can be created, saved, and instantly recalled. The last configuration loads automatically at power-up.

Relay switching provides exceptional reliability, low power consumption, and zero heat. The latching design ensures routings remain intact even after power loss. Because the signal path is effectively “just a wire,” ProPatch transparently passes mic level, line level, phantom power, control voltage, digital audio, and MIDI.

Rear DB25 connectors provide high-density I/O, while the front panel allows fast integration with TT systems and temporary gear connections. ProPatch removes the friction of manual patching, keeping sessions fast and uninterrupted.

All shipments are fully insured.

Bigger shipments requiring pallets or custom made crates ship to US, CA, JP, CN, AU and other outside of EU locations via DHL Air Freight, ETA is normally approx. 7-14 working days from pickup day zero.

Big shipments inside EU ship via different freight companies, recently mostly via ACE Logistics. Freight forwarders can use different courier companies for deliveries to final destinations.

Palletising and crating time can vary depending on the size of the shipment and packaging queue. We pack all our shipments with great care.
