Matrix Audio SI-1 Audio Grade Network Isolator
The Matrix Audio SI-1 is a network isolator designed for streaming audio systems where noise from the network can subtly but meaningfully degrade sound quality. Using active optical-electrical isolation, it blocks electromagnetic interference generated by routers and switches, breaks ground loops, and prevents the kind of low-level current noise that clouds the background and dulls fine musical detail. The practical result is a quieter, blacker background from which music emerges with greater clarity and presence.
The engineering behind the SI-1 is more considered than its compact form might suggest. A dual-channel optical transmission architecture separates the sending and receiving paths entirely, eliminating crosstalk at the source, while two femtosecond clocks and a linear power supply drawn from a potted toroidal transformer keep timing stable and power delivery clean. A single input and isolated output via dual 1Gbps RJ45 ports handle the connection, with the output port incorporating an electrical isolation washer that physically breaks continuity between devices, offering meaningful protection against surges, static discharge, and persistent mains noise.
Finished in a CNC-machined aluminium enclosure that sits comfortably within the Matrix Audio design family, the SI-1 is a thoughtful addition to any streaming system. Front LED indicators display device status clearly, and the rear Ethernet port LEDs can be switched off entirely to avoid light pollution during listening. It is a small but well-resolved component that works particularly well alongside Matrix Audio streamers and DACs, raising the overall performance ceiling of the system it serves.
Here is what Matrix Audio say about the SI-1
Matrix Audio SI-1 Audio Grade Network Isolator is a premium accessory meticulously crafted for Hi-Fi enthusiasts who pursue sonic purity. As a key extension of the Matrix Audio ecosystem, SI-1 not only carries forward the brand’s consistent commitment to precision engineering, but also unlocks new possibilities for cleaner signal paths in streaming audio systems. Working in synergy with other components, it elevates overall system performance, actively raising the ceiling of sound quality and reinforcing the very foundation of audio reproduction.
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.
Meticulous Design
The SI-1 is housed in a CNC-machined unibody aluminium enclosure that reflects the Matrix Audio design language, adding a layer of shielding against external interference alongside a premium finish.
Front LED indicators
The LED indicators on the front-panel displays the status of the device clearly.
Switchable LEDs on the Ethernet port
The rear-panel Ethernet port LEDs can be switched on or off to eliminate light pollution—demonstrating careful consideration for real listening environments and uninterrupted musical immersion.
Precision Matching
SI-1 pays tribute to every Hi-Fi light-seeker with a heart of pure sincerity. Designed to complement Matrix Audio streamers, it resonates with the audiophile's quest for absolute purity. As the optical masterstroke in your system’s evolution, it ensures that every passion for superior sound is brilliantly realized.
