(For reasons I don't understand, this message does not seem to be getting to the mailing list).  I've subscribed already.

I intend to use Audacity to transfer many vinyl albums to CD.  I've done one successfully with one amplifier feeding line-out to line in on a Soundblaster card.

I bought a used receiver to do these albumss that only has tape out (no line out).  When I feed this into the line-in port of the Soundblaster, it generates a relatively low signal on the audio track graphic, even with all settings at maximum (volume in control and Audacity record control).  The only way I can get the signal up sufficiently is to take speaker out into the line-in jack of the soundblaster with the volume turned down, and that doesn't seem like a good way to do this (extra amplifier, etc).

So I tried something else.  If I take the same tape out signal from the receiver and run it into the microphone-in jack of the Soundblaster card, it works fine with Audacity (good output on the audio track graphic).  I do NOT have the microphone set to do a +20db boost option, so that isn't why I'm getting better signal.

Is there any problem or risk for me to just use the microphone-in port on the Soundblaster from the receiver's tape out port for what I'm doing?

Thanks in advance for your advice.
