fills the most overlooked gp in your audiophile streaming setup, addressing noise, jitter, and signal integrity issues that cheaper commercial-grade switches silently introduce into your signal chain. Unlike traditional network switches, the SS-1 Pro/SS-1 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. The SS-1 Pro excels at grounding, power, and clocking with a CNC-machined chassis tied to a proper earth ground, a custom toroidal linear power supply with audio-grade filtering capacitors, and an internal femtosecond clock that delivers ultra-low phase noise for cleaner digital transmission. When you're building a reference system, every link in the chain counts. Higher speed, better performance The SS-1 Pro/SS-1 is unlike run-of-the-mill network switches. It's been developed with higher speed stems from the perspective of digital circuit design. A system capable of supporting higher-speed signal transmission will inherently have a higher stability limit. This also means that the timing error in high-speed equipment is relatively lower compared to low-speed equipment. Therefore, high-speed devices performing at low speeds exhibit superior performance compared to low-speed devices transmitting at the same low speed. Dual 10Gbps isolated ports with Independent Ethernet Sockets Two SFP/SFP+ ports with up to 10Gbps connection speed allow you to install optical fiber or RJ45 modules according to your needs. These ports make 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. But the SS-1 Pro/SS-1 doesn't stop there. Not only does it have multiple Ethernet ports with speeds up to 2.5Gbps, but it also has two low-speed ports that work at 100Mbps. To reduce the bit error that may occur during data transmission, the connection speed of audio devices can be reduced by connecting to these ports. Designed with independent sockets and wider spacing between the sockets, crowding is easily prevented when using high-end cables. Additionally, 10Gbps-grade independent Ethernet transformers and fully shielded Ethernet sockets are used. Each signal transformer is individually shielded by metal shells, enhancing resistance to radio frequency interference. External clock input & RF Synthesizer Matrix Audio understands how critical the clock system is for digital circuits, and network switches are no exception. Inside the SS-1 Pro sits a femtosecond clock and a high-precision ultra-low phase noise RF synthesizer, with support for two clock modes: Internal clock mode and external clock mode. 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 an RF synthesizer, it still features an ultra-low phase noise femtosecond clock as the reference for the main controller, ensuring exceptional performance. Flexible Design with Options for a Better Power Supply The precision-machined aluminum CNC chassis of the SS-1 Pro/SS-1 incorporates Matrix Audio's new design language, with a reinforced steel base and four isolation feet. LED status indicators on the Ethernet ports serve as a reminder of what's in use, but can be easily turned off by pressing the setting button on the rear panel. If you don't want them to interfere with your listening experience, they don't have to. To ensure upgradability down the road, the SS-1 is equipped with a DC input port, allowing you to connect an external linear power supply to unleash its potential performance. Bypass the auto voltage range linear power supply if you choose to, or leave it as is. When the DC input is connected, the internal AC input will be disconnected automatically. The external linear power supply provides clean power directly to the femtosecond clock and the main controller through the internal power line noise suppression filter and four ultra-low noise LDO circuits. Linear power, silent cooling 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. FAQs Can I use the SS-1 Pro with an external master clock? Yes. The Matrix Audio SS-1 Pro Audio Grade Network Switch supports external clock mode, accepting a 10MHz reference signal from an external audio-grade master clock, such as the Matrix Audio SC-1, which the internal RF synthesizer then uses to generate a phase-synchronized, ultra-low phase noise clock signal for the main controller. Will the LED indicators on the Ethernet ports affect my listening experience? The SS-1 Pro/SS-1 includes LED status indicators on the Ethernet ports to show connection activity. While they will not affect your listening experience in terms of sound quality, if you find them distracting during listening sessions, they can be turned off simply by pressing the setting button on the rear panel.
