A Cleaner Sonic Foundation

The Matrix Audio SI-1 Audio Grade Network Isolator features active optical-electrical isolation technology, effectively blocking electromagnetic interference generated by routers and network switches. By purifying network noise that can interfere with audio signals, it also breaks ground loops and prevents current noise caused by grounding potential differences between devices. The result is a deeply “black” background, allowing music to emerge with greater clarity and purity.

Precision in Every Detail

A dual-channel optical transmission architecture enables independent sending and receiving paths, eliminating mutual interference at the source and preventing signal crosstalk. Two femtosecond clocks, combined with a linear power supply by a dual-winding toroidal transformer and multiple LDOs, ensure stable and clean power delivery. This design ensures data integrity, reduces transmission errors and jitter, improves timing accuracy, and allows musical details to be rendered with exceptional precision.

Attentive Protection

Equipped with dual 1Gbps RJ45 ports (one input and one isolated output), SI-1 adopts a physically separated layout. The output port incorporates an electrical isolation washer, reinforcing signal integrity while significantly reducing transmission errors and completely cutting off electrical continuity between devices. Whether facing lightning strikes, power surges, electrostatic discharge, or persistent noise from the power mains, SI-1 forms a robust protective barrier for high-value digital audio equipment such as network streamers, music players and DACs—ensuring peace of mind and uninterrupted listening enjoyment.
