Innuos PhoenixNET

Phoenix caught in the net – Innuos have released their new PhoenixNET network switch for networked audio [€2'749]. "Having started with improvements to the Ethernet ports' clock on their flagship Statement server, Innuos have taken the concept to the next level with a completely new switch design focused exclusively on audio use. This targets four areas: noise, clock precision, power and vibration management." HF noise is reduced by avoiding switching regulators and using high-end isolation transformers for each Amphenol RJ45 port without LED but further EMI treatment. Derived from the Statement streamer, a 3ppb 25MHz temperature-controlled crystal oscillator runs off its own linear power supply and connects directly to the network switch chip. Two independent linear power supplies with Mundorf caps power the clock and motherboard while CNC-machined aluminium footers contain a compound tuned to the chassis' resonant frequency. The RJ45 ports also decouple from the chassis by silicone rings.
