Tonight a friend of mine slided his empeg in his car sled, and powered it up. We both started to hear a quite loud ground noise we had never heard before. The noise is constant, and seems to change slightly, somehow, when skipping to the next song. It also seems to amplify the hdd noise.
This happens with his empeg only, both in his and in my car. It also happens at home, when the empeg is plugged and is in AC mode.
At home, he usually uses a 12V 1A adapter. However, if he uses a 13.8V 3A adapter, the ground noise disappears.
We need help to sort this out. What can my friend do to solve this? Any idea on what may have caused the ground noise to appear only now?
Thank you all in advance.
