About the CAD USB Control
The Computer Audio Design (CAD) USB Control is a passive USB-port noise-reduction accessory for HiFi and AV equipment. It is intended to be inserted into an unused USB-A port—including service or software-update ports—rather than placed in-line with an audio USB connection. CAD states that it reduces unwanted high-frequency noise on the USB +5 V DC supply rail and signal ground, across a spectrum extending from kHz frequencies into the GHz range. It is suitable for unused USB ports on components such as music servers, streamers, DACs, routers and other digital audio equipment. CAD does not publicly disclose its internal circuit topology or filtering-network details.
