[dba-Tech] Converting LPs into digital audio

I have a moving magnet cartridge.  I just threw out the extra info on the
moving coil because I knew that there was definitely pre-amp circuitry when
that was used.

As for the second item. are you saying that you would still recommend a
separate pre-amp rather than going through the pre-amp in the pre-amp (that
sounds funny)?  

Also, I take it that I would use the output from the pre-amp that goes to
the amp as the input to the sound card.  Correct?

Thanks again,
Bobby

Yes to both questions.

If it is an pre-amp intended for recordplayers it is almost certain with
RIAA. If it has no RIAA correction you will not hear much bass in the music,
but you will hear music. Bass sound is reduced with 20Db before putting on
vinyl, so it would fit on to the vinyl. Thats why you need an RIAA
correction to increase the bass sounds with 20db (I believe its 20Db). A low
quality RIAA correction can have an offsett on the cut-off frequency or
increase more or less than 20Db. A turntable cell has an output of 1m volt
or less. A line input/output has 10 m volt or even more. A microphone has
also 1m volt, but the RIAA correction is not there so, you wont hear much of
bass.

You can also connect your turntable to a Phono entry of a Mixer or amplifier
end connect the output of those to your pc. It is my believe you will
posibly get more noise that way. So I rather would use a quality RIAA
pre-amp.

Moving coil or Moving magnet. Thats also an important one, you should check
the type of Cell you have on your turntable and set the pre-amp accordingly.
