Rebuilding a pure, convenient, and secure USB audio chain

On September 29, 2026, Matrix Audio officially launched the new SU-1 USB Isolation Switcher, which combines three core functions: multi-source switching, galvanic isolation, and regulated linear power supply on the output side.

For users with multiple digital audio sources and DACs, issues such as USB ground loops, high-frequency noise interference, and front-end power supply noise have long been a plague. The SU-1 provides a cleaner, more convenient, and safer USB audio chain management solution, restoring a secure and simple connection between digital audio sources and DACs, and unlocking the full sound potential of downstream equipment.
