[dba-Tech] Converting LPs into digital audio

For the the pre-amp or receiver pre-amp see my previous posting. 

Output of the pre-amp goes to the line-input of the computer.

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.
