Mac Forum / General / General / August 2008Sound Card in iMac - full specs??
Anyone know what the full specs of the sound card are in a 24" iMac ? Model before the current one... 2.4ghz Scoured the 'net but can only find a general spec. TIA Cheers Mal Oz > Anyone know what the full specs of the sound card are in a 24" iMac ? Model > before the current one... 2.4ghz > > Scoured the 'net but can only find a general spec. There's no sound card. The audio chip is included on the motherboard. You might try http://everymac.com to see if they list it for your particular model. What problem are you trying to solve?

No problems my friend, just curious. I'm a bit of music nutter, so I like to understand what's under the hood. Will try the link you suggested.

Bingo ! If you ever pop over to Perth - there's a beer waiting for you. Thanks. Mal Oz >> Anyone know what the full specs of the sound card are in a 24" iMac ?

The grounding warning box is worth a thought. On Laptops there is no line out. Therefore, are they compromised to green line ground? Most PCs do not have a separate line out that is electrically different than headphone. > The grounding warning box is worth a thought. On Laptops there is no line > out.

I feed the headphone output, after terminating both channels with 32 ohm load resistors, into unbalanced analog inputs of various mixers, all of which are grounded one way or another to same "green line" ground in the AC mains. The Apple notebook power supplies have two pin AC mains plugs (no grounding pin). In the USA one side of the AC mains is a neutral, which is essentially (usually) at ground potential. I have not checked to see how well the power supplies isolate the computer from the AC mains, but then that's because it has never been a problem for me. If it was, you could run it on its battery, without the power supply. The newer Apple laptops have optical I/O, which not only avoids electrical grounding problems, it sounds a lot better too.

Still the best audio work is done on an older Mac or PC tower where you can get a good sound card with plenty of fully grounded jacks and do whatever you want. ** Posted from http://www.teranews.com ** |
