Design and Build Quality
ProPatch boasts a compact 1U rack space design, making it an efficient addition to any professional setup. Despite its small footprint, it houses an impressive 128 patch points, providing extensive connectivity options. The rear panel is equipped with DB25 connectors for 48 channels of I/O, while the front panel features 16 TT I/O pairs, 4 XLR/TRS combo jacks, and 4 TRS jacks for easy integration with existing systems.
What sets ProPatch apart is its relay-based architecture, designed for maximum durability and performance. These telecom-grade relays are rated for millions of cycles, ensuring long-term reliability without the need for constant maintenance. Additionally, the design eliminates the need for active electronics in the signal path, preserving the audio's natural quality.
Unparalleled Audio Transparency
The hallmark of ProPatch is its ability to maintain 100% audio transparency. This is achieved through a design that completely removes any electronic interference from the signal path. Unlike traditional patchbays that might introduce unwanted coloration, ProPatch’s straight wire performance ensures that what goes in is exactly what comes out—pure, unaltered audio.
ProPatch operates with zero noise, crosstalk, or distortion, making it an ideal choice for mastering engineers and high-fidelity recording environments. The use of latching relays means that even when power is lost, the current routing remains intact, providing reliability that’s essential in critical audio applications.
Advanced Routing Capabilities
ProPatch doesn’t just route audio; it transforms how you manage your audio workflow. The Wolff Hound utility app allows users to create complex device chains with ease. You can drag and drop devices into mults, mono-to-stereo conversions, inserts, processors, and AB comparison blocks—all of which can be saved, recalled, and modified instantly.
With support for USB-C, Ethernet, and Wi-Fi, ProPatch integrates seamlessly into modern studio networks. The ability to instantly recall routing presets means you can switch between sessions or live setups without missing a beat, enhancing efficiency and creativity.
