Hi all,
I recently (this morning..!) bought a digi 002r after using logic for a long time (+motu 828 recently..) Ive read about power supply noise issues with (I think) the digi 002R and the G5's - I have encountered the same thing with my 12' powerbook (40gig/640mb/OS X 10.2.8). the digi 002r sounds fine... until I plug the power supply in... then lots of noise...! I downloaded CHUD tools, disable Nap, and that has helped a bit (its probably bearable now (not really what I was after with a new £900 audio interface though..!) I know the 12" powerbook is 'untested' according to digidesign, the few shops I spoke to all said it'll work fine wih my powerbook.... Does anyone know anything about this? It sounds like some kind of earth thing (not really an electrrician), any help would be greatly appreciated! Thanks. Aaron |

These noise issue when the power supply is plugged in are referred to as ground loop problems. I have experienced them with my pc notebook and it has been an experience trying to get rid of th e problem. I was hoping that Mac would not have the problem as the result of superior shielding. I hoipe this is only an isolated issue becuase I have considered getting a powerbook.
With pc notebooks, there are a few solutions. One is to use a three to two prong adapter to eliminate the ground, but that can be potentially dangerous. I've heard that using a DI box can help. Some people have had some success using a Ground Loop isolater, which is a device you can get at Radio Shack. |
