SS-1 Pro is an audio-grade network switch specifically designed by Matrix Audio for Hi-Fi streaming audio scenarios. Unlike traditional network switches, this product is meticulously engineered to meet the requirements of Hi-Fi audio systems. It includes comprehensive enhancements in its power system, clock system, cooling methods and component selection, all focused on ensuring the lossless transmission of high-definition streaming audio.
Two SFP/SFP+ ports with up to 10Gbps connection speed allow you to install optical fiber or RJ45 modules according to your needs. This makes it possible to connect both upstream network devices and digital audio players simultaneously through SFP ports, achieving complete electrical isolation between network devices and audio equipment via fiber optic cables. This prevents high-frequency noise or interference from network devices from being transmitted through the ground wire into the audio equipment.
The clock system is critical for digital circuits, and network switches are no exception. It can be likened to a series of high-speed switches that must operate with extreme precision. Inside the SS-1 Pro, this system consists of a femtosecond clock and a high-precision ultralow phase noise RF synthesizer. The SS-1 Pro supports two clock modes: In internal clock mode, the internal femtosecond clock serves as a reference for the RF synthesizer, which then generates a highly stable, low-phase-noise clock signal for the main controller. In external clock mode, the 10MHz clock signal from an external clock acts as the reference for the RF synthesizer. The DPLL then outputs a synchronized, highly stable, low-phase-noise clock signal to the main controller. Even though the SS-1 has a simplified clock system design and does not have a RF synthesizer, it still features an ultra-low phase noise femtosecond clock as the reference for the main controller, ensuring exceptional performance.
A custom o-core toroidal transformer combined with high-speed Schottky diodes and nearly 10,000 uF audio-grade filtering capacitors forms the first-stage power supply of SS-1 Pro. Up to 6 ultra-low-noise LDO linear power supplies provide clean power to the clock system and the device's main control chip. The large passive heatsink for the main control chip, ensuring it operates without generating any noise.
