turntable to computer - another question

If you were to search the web for a 'USB interface' you will find lots of them available. M-Audio do a USB version of their 2496, and other companies such as Behringer, Edirol and others offer similar products. They go from a few 10's of dollars up to professional kit at several hundreds of dollars. Most USB interfaces should work for playback as well as recording, so for playing back your recorded files you can use the 'cleaner' external soundcard - that's a whole different topic though, and one which has filled up lots of space on forums. One thing to consider is the type of input connection you will be using, most probably RCA 'phono' plugs. On this matter it is worth pointing out that the software I mentioned above (Acoustica) has in-built RIAA equalization. This should mean that you can plug your turntable direct to your audio interface instead of via an amplifier. This is a feature which wasn't in the software when I used it, but if it works, then it could make things a lot easier

Alebobsing-
Thanks for the info. So if I use software with RIAA equaization, I don't need a phono amp?

That's my understanding. I have provided this link for your reference: http://www.acondigital.com/us_Acoustica1.html
Don't get confused with other products with the Acoustica label, though.

If you read the information it describes it as "software emulation of phone preamplifier". They provide a trial download. If you have the inclination, check it out.
Regards and good luck,
Bob
