Transfer LP records to CD via computer

I'm trying to get a signal from a Kenwood turntable into my computer "line in".

Here's the background: I have an audio cassette tape player that will not play sound on its own. I can connect it to the "line in" jack on the computer via RCA cable from the player converted to a 1/8" stereo plug at the computer "line in" jack. The tape sound then plays on the computer speakers and records in SoundForge software simultaneously.

When I try this with the turntable the only sound I can hear is a low sound at the needle. What do I need to do to correct this? The research I have done leads me to think I need a preamplifier??

Before I buy a preamp, I would appreciate some input from anyone who has technical knowledge in this situation.

You did not specify any details about the deck. If the output is direct from the cartridge, you have to have a preamp. The output from the cartridge is very low level and non-linear. Some Kenwoods had the equalizer built-in. Which model? Does the cassette deck amplifier actually work?

If you have a lot you should also consider using something like AudioLava which will split the record into tracks and has a simple de-noise wizard. For perfection you would still need to use your SoundForge for the troublesome spots.

Edit: FYI the Kenwood P-110 can go directly into any auxiliary input so you would not need the cassette deck. You would have to try it to see if the signal level is high enough.

Thanks. The turntable is a Kenwood KD-42RB. I know very little about turntable components so I'm not sure about the output being direct from cartridge.

The audio cassette tape player is a RCA SCT-510. It has no speakers so perhaps it has a built in preamp since it will do the job thru the computer.

If you need more info, please advise.

I could not find any information on that model. If the output from the deck is RCA (Phono) sockets, try connecting direct to your Line-In.

Some cassette decks that I've met only give an output from the input when you are recording, unless there is a monitor switch. You may have to put it on Record to get an output. If the tape has to be present, Record then Pause.

I recently bought the turntable used so it might be an old model. The tape deck works fine from its RCA out direct to computer line in. Its the turntable that will not work thusly. I tried connecting the turntable via RCA to Aux in on another working stereo and still no amplified sound.

The only way to test the deck output would be to find an amplifier that is known to work OK with a deck. It would have an input labelled "Phono". You could take the bottom(?) off the deck (protect the tone arm) and see what electronics are inside if any. If the cartridge is direct-wired to the output terminals you will need a preamp (or one integrated into an amp).

A cassette deck is unlikely to have an input for a direct cartridge connection.

Ok I will follow up on that when I locate an amp. Thank you for all your advice!
