Ibasso D2 White Noise

post #1 of 6
Thread Starter 

I just got my ibasso d2 today, and it produces some kind of white noise which is quiet but is noticeable.  When I turn my d2 off it makes this weird kind of noise.  Is this normal?  I'm using it with my m50s if it that matters.  I'm not sure if it's called white noise but it's like the kind of sound you get when you crank your laptop sound up with headphones on.

I've also noticed that the D12's input manager seems to be doing a very good job as compared to the D10 (which already worked well).  As I change inputs or turn sources on and off, the D12 is picking them up flawlessly whereas my D10 occasionally has to be turned off and on again to acquire the signal.

Yes, this is normal behavior.  As the power reserve in the caps is exhausted, the opamps often oscillate a bit before shutting down completely. 

 

Such sound is perfectly harmless.

 

 

 

 

 

It's normal, don't worry about it.

I am so relieved that it is normal because mine is mini-audio and I'm not sure if Ibasso will do anything about it.  I dont live in China but I got it because I had relatives coming from China.  Will this "white noise and swooshy sound" thing go away later or affect the sq?  Thanks everyone.

No and no.

 

Nothing to worry about.
