Aha!

I've just realized I can record all my LPs and tapes to MP3 format if I get an adaptor and plug it into the microphone jack. I can even do it on the Portable Mousehold, so I don't have to move the record player upstairs.

*is genius!*

Soon, I'll be able to listen to Golden Avatar while driving! Hmm. All those years wasted, drooling over USB turntables...

EDIT: Wait - would it need to be plugged into the line-in port on the sound card? Cause the Aspire One doesn't have a line-in, just the mic jack. The Fortress Computer in the basement may need to serve instead - it'll just need a longer cable.

Sure, give it a try. Nothing to lose.

The situation is this: most turntables put out a sub-line signal, requiring a pre-amp before the 'line in' jack on an amplifier. Most mic jacks 'expect' a sub-line signal - that's why you often find the '20 db boost' option in the advanced properties for mic jacks, to goose the signal up further. So, you *might* get away with plugging a turntable's unamplified signal through a dual phono F to 1/8" stereo M jack adapter.

Or, y'know.. go crazy. (http://www.newegg.com/Product/Product.aspx?Item=N82E16882698003) n.n

I think I'll give it a shot on the Aspire One, since it allegedly has a stero mic. It's also possible the mic doubles as the line in, isn't it? Since it's small and stuff?

There is one other thing to consider, which is this. Most mic jacks also expect an electret mic (http://en.wikipedia.org/wiki/Electret_microphone) and apply a biasing voltage for the transistor they expect to see downline. Most, if not all, audio gear should be AC coupled and not be bothered by a DC offset from the far end of the cord, though.

Beyond that, and the preamp you mention, I *think* there is functionally very little difference between mic and line in jacks.

Oh, and Pyat, it's not like you can blow anything up, here. As I understand it, the WORST that could happen is you saturate whatever transistor is listening for the signal from the record player, and that just makes the recording clip.

Also, I do have a nice 70s amp in the basement, with lots of flickering needle gauges and stuff!
