The CAD USB Control is optimized specifically to reduce high frequency noise in USB connections. The USB Control is a small thumb-sized device that can be inserted into any available USB socket – including software update ports – on components in your audio system. Music servers, routers, network switches, digital interfaces, etc. can all benefit from a reduction in high frequency noise. Typically, the USB control will deliver enhanced clarity, larger soundstage, and improved timing/rhythm in any music system.
