The Architect of Pure Sound
Enjoy Flawless Pure Sound Quality
SI-1, an Audio Grade Network Isolator designed to purify network noise
In the age of digital audio, network transmission noise, ground loops, electromagnetic interference, jitter… these invisible forms of “noise” are affecting your sound quality quietly.
To address this, 「Matrix Audio」 introduces the SI-1 Audio Grade Network Isolator on February 25, 2026. Engineered to purify the audio signal at the network data chain, the SI-1 builds a clean, stable, and secure “digital shelter” for your Hi-Fi system.
The SI-1 achieves comprehensive sound quality improvement through a suite of core technologies:
Active optical-electrical isolation technology, eliminates noise from network transmission.
Dual-channel optical fiber transmission with independent transmit and receive paths.
Dual-winding epoxy-potted toroidal transformer with multiple LDO linear power supplies.
Dual femtosecond clocks.
2x 1Gbps RJ45 ports: one input port, and one isolated output port.
Front-panel connection status indicator, making the working status clear at a glance.
Physically separated RJ45 ports, dedicated isolation washer on the output port.
Full aluminum CNC enclosure, Matrix Design language.
The Ethernet ports LEDs can be disabled to reduce the interference of light to the listening atmosphere.
The SI-1 can be flexibly deployed into various scenarios. It can be added before the audio or video devices which feature an Ethernet port, to isolate the streaming devices from the home network. Or put between the incoming network router and the audio dedicated network switches. As the most important isolation node between the audio network and the entire home network. To cut off interference and noises, reduce jitter, providing a purer and more stable digital data transmission environment.
The SI-1 Audio Grade Network Isolator allows every music enthusiast to hear the purest, most authentic sound.
