The AS8Pro machine is divided into three main parts. 2.5G main switch+1G audio quiet zone+ultra-low phase noise precision clock. All in One design, fully functional trinity and independent isolation from each other.
2.2.5G main switching area and 1G audio quiet area are connected for communication through built-in single-mode dual fiber, achieving optoelectronic isolation and providing the purest network environment for digital broadcasting.
3. The clock area adopts SC cut OCXO with near end noise better than -110dBc, combined with high-performance PLL clock chip, to provide the most precise and stable synchronous clock signal for the two switching areas. At the same time, clock input and output ports are also configured for customers to further upgrade.
4. Equipped with two 50VA imported porcupine ring cattle and multiple uV level fully linear DC stabilized power supplies. Compared to competitors who only use linear power supply for the first level and DC2DC power supply for the rear end, AS8Pro is a truly linear power supply without any DC2DC circuit on the board.
5. The chassis is made of a whole piece of aviation aluminum material, which is excavated through CNC precision machining. Compared with conventional assembled aluminum alloy chassis, it greatly reduces the overall resonance of the machine and improves the rigidity of the chassis. Different functional circuits can be isolated from each other to avoid interference.
6. The independent grounding terminal and grounding switch designed specifically for audiophiles with extreme requirements can enable star shaped grounding between multiple devices in the entire audio system, thereby avoiding interference noise caused by ground loops.
