I have a U Track 24 and when the unit is on and hardrive connected you can hear a high pitched noise which is really loud.Sounds like a hardrive information noise but have purchased a new hardrive and it is still happening.It only happens when its connected to a speaker system and Im using 1/2 at the rear of the unit. Tried balanced an unbalanced leads. Any ideas anyone. Thanks.
This sounds like a ground loop or grounding related issue. Is your speaker is an active speaker? -> Is it connected to the same power socket like the uTrack24? Is the speaker amplifier grounded?
