Background Noise when recording onto CD from LP's

When I record LP's onto my PC via a pre amp and the line in socket, the sound quality on the pC is fine. When I transfer the files to CD I get a backgroung 'HUM' similar to electrical interferance. This renders the CD useless.
Can anyone help!

I presume the recorded file on the disk is a WAV file. As the process from there to the CD is all digital the hum (again presuming mains hum at 50Hz) is in the file already. If you can't hear it when you play the WAV file back thru the PC speakers, it may be that the PC set up has a limited bandwidth.

Can you play the WAV file (lineout) through a hifi and listen for the hum.

If it is there, then it's being added by the pre-amp.

Sorry about all the asssumptions - you've got to start somewhere...

Hi. Try this!

When recording to the HDD, have the pre-amp gain up as high as you can. This should increase the signal to noise ratio giving more signal and less noise at the HDD end.

If that doesn't work, make sure the the recording cables are not coiled in a loop or run adjacent to a power cable as this may induce hum.

You should also be using high quality co-axial sheathed cables.
