Digi 002r/power Supply Noise/powerbook G4, Anyone seen this before? Options

[ronfinch]

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

honestly, Powerbook G4's are PERFECT for the 002/002r's. They have about the same processing and memory bandwidth as the desktops minus the graphics and pci expansion ability that isn't necessary in a NATIVE protools setup that is the 002/r. Powerbooks aren't "technically" supported by Digidesign but Digi is uptight and it works fine. The only downside is the hard drive. It is recommended by just about everyone important to digital audio that you have a drive @ 7200 rpm's and a seek time less than 7.9ms (i'm not positive about the seek time... could it be under 8.2?) to record live audio. You can do this by opting for an external firewire drive or grabbing the most expenisive internal at the apple store.
