Description
The new Matrix Audio SI-1 Audio Grade Network Isolator is a premium switch alternative for Audio enthusiasts that only use one Ethernet Port.
The new Matrix SI-1 is meticulously crafted for Audio 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 SI-1 features 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.
The SI-1 features a Linear power supply with dual-winding potted toroidal transformer and multiple LDOs.
The new SI-1 is quipped with dual 1Gbps RJ45 ports (one input and one isolated output), and 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.
The SI-1 features a CNC unibody aluminum enclosure that not only delivers a premium touch, but also enhances shielding against external interference.
