What should I do if I hear a noise coming from my Devialet Expert or Expert Pro in stand-by?
Although there are no moving parts inside a Devialet, you may hear in some cases an extremely soft noise in stand-by. There is absolutely nothing to worry about. It is caused by the vibration of some ferrite elements in the power supply. The level of this extremely low noise varies from unit to unit. Again, there is absolutely nothing to worry about.
