Noise sources

Audio manufacturers have known about these issues for many years and most equipment is designed to reduce ground loop generation to the bare minimum or to minimise the effects. But, as switch mode power supplies and computers become more common place, the earth/ground environments that audio systems operate in become more and more contaminated by noise currents from both within the system and from external sources.

The USB connection on the VeniceU is an example of this. The high speed nature of the connection necessitates a good screen ground to bond the computer to the VeniceU. However, if the computer is grounded via its power cable a ground loop will exist that can inject current into the console chassis and may produce currents or small voltages that can affect other externally connected equipment. The size of the injected current will vary from one computer to another, depending on the quality of the grounding and components used internally, and within its power supply. To eliminate this problem, computers with an isolated power supply are the best choice.
