I think it's time for you to change your handle from GermanGuy to GermanGenious.
Has anyone else noticed a piercing hiss (for lack of a better term), when a metal object contacts the case, or the case is grounded? It seems to only happen on the left channel, on my unit. Easily avoidable, and I only noticed it by accent, but I am curious.
interesting, have to think about. some questions:
- don't understand how this sound sounds
- any metal object or a special one
- maybe a magnetized metal object
- are you sure your ground is really ground.
- does this happen without signal and input cables, volume turned down to zero
the first crystal radios just worked by connecting one side to real ground and the other to an antenna of fitting length.
you can be an antenna when touching a grounded but not shielded device.
is your input cable a coax type and the inner wire the right but the outer wire the left channel?
Very high frequency burst that hurts the eardrum.
Has only happened when the metal object (seemingly any metal object) was in my hand. Ground related?
The objects were not magnetized.
I am not sure my ground is really ground.
Don't know about the volume knob. Has only happened twice, but when it happened the sound of the pierce was of much higher volume than I ever listen. (And sometimes I do listen loud).
I can't answer your last question, my input is an 8 strand BTG cable and I don't know how it's wired. I can probably find out if necessary.
