[dba-Tech] Converting LPs into digital audio

It should be efficiant...
I'm only afraid that pre-amp riaa inside an receiver/amp or mixer is
lower quality than a seperate one.
But I supose the worst thing that can happen is you need to give a bit
more or less bass....

However there can be some probs with this if other equipment is
connected to the same output.
I have a +/- 20 meter cable running from my living amp to my bedroom amp
and notice a difference in sound in the livingroom (the source) when the
cable is plugged in or not... 

So I think that one should avoid as much equipment as you can thats in
between the turntable and the computer. I read (forums) at least two
problems with the ground when using a mixer of receiver/amplifier. The
difference in ground caused a pretty hearable humming sound.

Grandmaster PvG,

So, you were a disco DJ AND a radio DJ? My time in radio was the most
fun I ever had at a job. I did some dance DJ work, too, but it was
mainly for weddings and reunions.

Thank you for your detailed answer. When I recorded those voice tracks
off of LP almost four years ago, I did, indeed, use my laptop, so your
warning about the audio quality of the laptop sound card is right on. At
the time the laptop was over three years old, too.

Since we played those old Whamco LPs to death while I was in radio, I
wasn't too concerned that the quality wouldn't be very high. The LPs
were cut in 1982 and I didn't try this analog-to-digital routine until
18 years later.

I appreciate all the advice, though I'm not sure what to do about the
pre-amp. When I made my original recordings, my turntable was connected
to my receiver, and I used the audio-out from the receiver into the
line-in on my laptop. Would that be sufficient do you think? Or should I
not use the receiver?
