Hello to all.
Haven't written anything here for a while but recently  this started to bother me more especially  as my amps are still under DEVIALET warranty .

I am attaching  a video clip of the problem.
Anyone else with the same issue?
Don't think it's normal as my other one is almost silent....
This sounded just like the interference that was heard in computer sound cards many years ago.
Is this noise heard on all audio inputs or only some?
If you remove all the cables (except for the power supply and the one for the speakers), is this noise still heard?

Hello.
As far as I know it is always same and seems not related to what inputs are on or connected.

The other unit I own does not have this problem.
Did you change power cords?
If the problem is not related to which input is active then it suggests something wrong with the internals of your Pro.
What does Devialet say about it?

I suggest you contact them. They’re very accommodating regarding repairs. 

Good luck
