Isolate your network switch – That's Aqua Audio's LinQ. It distributes incoming Ethernet over RJ45 to single and dual AES/EBU, coax, BNC and Aqua's I²S over RJ45. USB is notable for its absence where the firm prefer the sonically superior I²S format. As a modular design with built-in LAN switch that's designed in house and requires no network configuration, each vertical board is fronted by its own power supply and galvanically isolated. Currently available network cards are RAAT and UPnP DLNA.
