Matrix Audio SI-1

High-end network isolator for audibly better sound

The Matrix Audio SI-1 was specially developed to elevate the sound quality of high-end streaming systems to a new level. As an active network isolator, it removes interference from the home network before it reaches your streamer, music server, or D/A converter. The result is significantly more precise music reproduction with more detail, a larger soundstage, and an exceptionally black background – for a relaxed and authentic listening experience.

Active opto-galvanic isolation against network interference

The SI-1 uses sophisticated opto-galvanic isolation technology, in which the Ethernet signal is internally converted to light and subsequently converted back. This creates complete galvanic isolation between the home network and the audio system. High-frequency interference (EMI/RFI), ground loops, and electrical influences are reliably eliminated before they reach your hi-fi components. Thanks to separate transmit and receive channels, the signal remains absolutely clean and free of crosstalk at all times.

Dual Femto-Clock with active re-clocking

Unlike passive network filters, the SI-1 actively optimizes the data signal. Two high-precision Femto-clocks completely re-clock all network data and reduce timing errors (jitter) to a minimum. The result is even more precise signal transmission with audibly improved detail resolution, more stable spatial imaging, and a natural, musical reproduction.

Audiophile linear power supply for maximum signal purity

The high-quality signal processing is supported by a powerful linear power supply with an encapsulated toroidal transformer and separate windings. Multiple ultra-low-noise LDO regulators supply each circuit independently with exceptionally clean power, creating optimal conditions for the sensitive clock and isolation electronics.

Reliable protection for streamers, DACs, and music servers

The SI-1 features one network input and one fully galvanically isolated Gigabit output. As a result, it not only protects high-end hi-fi components from network noise, but also reliably protects them from surges, electrostatic discharges, and unwanted interference from the home network.

Solid CNC-machined aluminum housing

The low-resonance unibody housing made of precision-milled aluminum reliably protects the sensitive electronics from mechanical vibrations as well as electromagnetic interference (EMI/RFI). At the same time, the high-quality finish underscores the uncompromising premium standards of Matrix Audio.

Switchable status LEDs

For an undisturbed listening experience in a darkened room, all status LEDs for the network connections can be conveniently deactivated. The discreet front LEDs provide information about the current operating status at any time.
