I can not afford to purchase an all singing and dancing box of tricks so
that I can record my LP's to my PC.

Would anyone have a circuit diagram for phono in and USB out please, or
even phono in and 3.5mm jack plug out so that it could be plugged into the
back of PC

I would like to thank everyone who took the time to answer my request for
information. I think I shall be having a close look at this.

I have the
majority of the components in the junk box just have to make the boards.
Thanks again

Try plugging it in the MIC input of your source card.


Not terribly helpful advice Jamie.

And in any case, It does work with my sound card on the PC
I have now. Last year I connected my direct drive Realistic turn
table to get some of my old albums over to CD.. It works very
nice.

You know, I don't care what they say about you, you can be
civilized now and then! :)

Why waste your time. All your tunes have probably been posted to
usenet hundreds of times already. Get a good newsreader, learn to use
it (filter out google, etc) and enjoy the music.......

The sheer joy Al of doing it oneself.

I take your point though.

Yes, you need a preamp with RIAA EQ. Connect the output of this to
your sound
card's line input.

On Semi's AND8177/D has a very suitable example. See Figure 3. 2
required one
for each  channel of course. You don't HAVE to use the precision
values
indicated like 49.9 kOhms but it's easy enough to make them up by
putting a
couple of resistors in series (or parallel).

A _possible_ problem with this approach is overloading of the line
level input. Perhaps other motherboards behave better but my Gigabyte
sound input has the gain control after the input stage. Signal levels
less than 2 V p-p cause problems for me. The cheapy solution I use is
an in-line L-pad attenuator constructed on a 4 RCA jack strip from
Radio Shack.
10k0 in series with 2k32 to ground works well for me.

Why not. The MIC input could be sensible enough for the phono output
and the RIAA equalization could be made with Audacity.

An external preamp is better.
Click to expand...
MIC inputs are notoriously noisy, besides being mono. They also tend
to deliberately roll off the high frequencies (above 9 kHz or so),
whereas LINE inputs are usually flat up until nearly half the sample
rate.

But there is another problem with software equalization, even assuming
you knew the mic input reponse and could correct for it: The RIAA EQ
curve requires a lot of low-end gain. When you do this with software
it is obviously done *after* the A/D quantization, which means you are
boosting the quantization noise (by about 18 dB at 40 Hz). This isn't
by itself a deal-breaker since it only means you have effectively a
13-bit A/D instead of a 16-bit at those frequencies, and the vinyl
noise will probably mask this loss anyway (or self-dither it). But in
general it makes sense to avoid this issue if you can.

Just a thought...

Sensible ? You mean sensitive ?

2 things. MOST mic inputs by far are MONO ! AND the input impedance is
totally wrong for apickup cartridge..


and the RIAA equalization could be made with Audacity.

How exactly ?

Jeff is right, if you dont have the proper equalization for your cartridge
the reproduction wont be good.

How about taking the phono out, plugging that into sound card's Line
In, then using Audacity to capture the music?

All you need is a wire like this

Yes , what you need is a stereo, connect your phono

to its phono input and connect your stereo line out to
your sound card line in.
Added quality: connect the metal case of your stereo to
the metal case of your computer.
And clean your records carefully.
Oh, and use indeed audicty to record.
