Our system builds outwards from the 'hub' module, attaching seamlessly via two USB ports on the PS3 Slim's front face. The 'Main Hub' offers three fully powered USB ports neatly concealed behind a dust excluding door. An infra-red receiver is built into the main hub for use with all your infra-red peripherals, the receiver is wide-angle for greater line-of-sight reception. The 'Retractable Module' offers a mini USB charge cable which retracts neatly behind a dust excluding door, keeping the components clean and maintaining a sleek exterior.
