I want to transcribe my LP's, tapes etc to CD. The problem is that the
only output from my old tape/record/tuner box is the loudspeaker leads.
I believe that these will not match the Line In on my PC

I think the signal may be too great and that it needs attenuating.

Am I right? Can this be done and how precisely may I achieve this. I
have no problem using a soldering iron

Many thanks

Maplins sell a small in-line variable attenuator (~£3) designed for stereo
headphone usage. I've got one sitting between my amp's output and my PC's
soundcard - it's allowed me to set the PC's input attenuators round about
3/4 full scale, instead of being close to 1/10 FS where the slightest nudge
is problematic.

I don't suppose you have a reference for this, When I put "attenuator"
into their web site search box all I get are a couple of TV attenuators

That's a relief - I'm not the only one who finds these extensive catalogues
difficult to navigate!

Try " L43AF" - "Headphone extension cord with volume control". It uses
3.5mm stereo connectors, male one end, female the other. It's 2.99GBP.

I note that their paper catalogue has two quite different areas for
headphones, and that this volume control only appears after the 2nd. area.

Wire the track of a 100k pot across the output, and the slider and ground
to the input. Adjust to taste. You'll have to fiddle with the LS level to
get the best results, but start about half way.

Is it worth copying LPs from a crappy old radiogram?
Especially as they will be worn out now after being
played on it.

If so, you could take an output from the top and bottom of
the volume control, which would be a better level and less
distorted than the speaker output.
Wherever you take the output from, check you don't have a live chassis.

Thanks for that I would never have found it otherwise

The thing is I have some old limited edition discs which have tracks
unobtainable elsewhere.

Would these need attenuating?

hi mike,
talking about maplin they do a isolation transformer for car speaker
output to line level, this unit will be great for your application
becuse it not only give the antenuation required but also isolation
thereby no problem with earth (hum) loops which is likely.
they call it high low matching transformer part no VW44X about a fiver
regards
bob

All the more reason for doing it properly.
A clean and possibly a wet playing on a decent turntable.

May we ask what discs these are?

The level at the volume control should be reasonable for a
PC soundcard line-in.

Great if you have one. I want to see if I am happy with the result
before investigating other options. The point here is that if I did
need to obtain high quality kit it would very soon become redundant
again, unless you know where I could temporarily obtain one from

Back in the 70's I used to frequent a folk club where the artists often
had their own LP's for sale. I also have some promotional copy only
versions

This sounds good but I think I will try the transformer suggestion
first as it will be quicker to implement

Thanks

Would connecting the sound card inputs to the tape record/output on the
amp/receiver work?

Hmmm.... another "folkie"!
I got a few from the local club too. "Happy Daze" as Bob Williamson signed

Yes, that is the simplest solution! I'm surprised that no-one
suggested it earlier.

The OP asked how he could borrow a decent turntable for the purpose of
transcribing his software. I would be happy to let him use my kit
(Linn LP12-based) if he can get to my place, in Exeter. Perhaps we
could even find a solution to my ground-loop problem!
