Matching to Line In
 

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

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.
