Ground Bounce

anonymous 27 April 2008

Hi,
When playing back tracks from my laptop on other peoples amps if I use my AC cord for power on my laptop I get a lot of ground bounce. If I run it from the battery problem solved... For an hour or so.
Short of running an extension cord from a neighbours how can I kill this noise?
Any help would be appreciated.
Thanks.

Get a better-quality power supply for the laptop that does not generate so much noise on the ground line (not "ground bounce" - that is something altogether different associated with switching logic).

Thanks Boswell, indeed you are correct.
