CAD USB Control

The new CAD USB Control design resulted from our research and development of the CAD Ground Controls, 1543 MKII DAC and the many USB cables we have produced over the last 10 years.

In our experience, reducing unwanted high frequency noise in audio systems significantly improves sound quality.

The frequency of noise varies in every audio system and in each domestic environment – even the time of day on mains power. The USB Control reduces this unwanted high frequency noise across an extremely broad frequency spectrum, from KHz up into the GHz range.

The CAD USB Control is optimized specifically to reduce high frequency noise in audio components by connecting to unused USB ports.

The USB Control is a small thumb-sized device that can be inserted into any available USB port – including software update ports on any components in your audio system.

The CAD USB Control will reduce higher frequency noise on both the Signal Ground and +5Vdc power.  This +5Vdc power is used in all USB connections, but in many audio components this same +5Vdc is also used in crucial audio circuitry.

Like all CAD noise reduction products, the CAD USB Control reduces high frequency noise using CAD developed technology.  The USB Control is designed to improve rhythm, timing, soundstage, and musicality of your music and will not “slow down” and harm sound quality as some other noise reduction products can do.

Music servers, routers, network switches, digital interfaces, etc. can all benefit from a reduction in high frequency noise. Anywhere you have an unused USB port in your audio system simply plug in a CAD USB Control and enjoy!
