Phoenix Audio Technologies' Quattro3 Power Hub MT340 is designed for use with the MT304 Quattro3 USB and Power Daisy Chain (sold separately). The Quattro3 Power Hub MT340 is a small unit that is positioned next to the computer and connects through a standard USB cable and a proprietary 48V AC/DC power adaptor. The Power Hub is then connected to the master Quattro3 unit via any standard CAT5 cable. Both data and power are routed to the Quattro3 through the CAT5 cable, allowing the PC to be up to 100 feet away from the first Quattro3 unit. The Power Hub also supports power daisy chaining when connected to Quattro3 units that support power daisy chaining.
