I've been trying to connect a Technics SU-V98 amplifier to my PC so I can record LPs and cassettes from the Technics turntable and cassette deck that were originally part of this audio system. Regular playback of either LPs or cassettes via the system's speakers works fine. I can bring in a single channel (left) via a connection from the amp's headphone jack with a stereo cable that connects to my PC sound card's line-in jack. When I tried a stereo connection from the amp's Tape REC-Out jacks to my PC, I get nothing. The audio system also includes an equalizer, if that makes any difference. Also, I'm using Audacity software to convert, and I've successfully recorded the one channel to WAV and MP3 files. As expected, the MP3 file only produces sound to one ear bud.

Thanks for any help that may be provided.

IF my prev. answer was not helpful. Try changing settings in Audacity to record in Mono. Then, after recording, cover t the mono, into a stereo. This will allow signal to both left and right. hwoever any difference between left outputs and right outputs will be nullified. However thsi will not affect LP's as they ar eMOno anyway. But newer casstes are sometimes Stereo, so you might get a loss there.

You don't need to purchase a pre-amp or spend much money at all. Jason is...well... wrong. There is no "proper way" to do this. Anyway that suites you is fine. The SU-V98 is fine to convert anything. there are two ways ways to do this:

I: Use a coaxial (L and R) wire to 3mm jack (headphone jack): Purchase a cable mentioned before and plug the coaxial into the graphics equalizer out jacks on the Integrated Amp (Su-V98) plug the 3mm jacks into your line-in on the computer. use software such as Audacity or equivalent to record your LP's.
PS. Using jasons tape-out method will work too, however The SU-V98 produces distortion on the Tape out, the quality is far far better on the graphics eq out.

II using a 3mm to 3mm cable: purchase mentioned cable. plug in the 3mm into the head phones port on the amplifier. (Buy a old jack to new jack converter first, the headphones out on the Su-V98 is very large and belongs to pre-3mm popularity times). Plug the other end of the 3mm cable into your line in on the computer. Go ahead and record your LP's.

NOTE: be very carefully of the foll: connect the turntable only into (ONLY ONLY ONLY) the Phono jacks on the int. amplifier.
Never ever connect anything else into the Phone jacks. As jason mentioned, turntables provide very very low voltage outputs and need an amplifier. also the amplifier will need higher sensitivity to receive the phono signal well. Pre-amps will not work! The PHONE jacks on the SU-v(* are extremely sensitive to get crystal clear reception. Also any other equipment (eg. tuner, tape deck, cd player etc...) will produce higher voltage outputs that can and will short the phone jacks if connected to them.


PS
forgive my hasty typing, am in a hurry, but could not help answering your question. Jason seems bent on making people spend money unnecessarily.

I would suggest that you plug the 2 RCA cables from the turntable into the amp where it says "phono" ... then go to the store and grab a [3.5mm to 2RCA cable] and plug the headphone plug (the 3.5mm end) into the back of the PC and the 2RCA cables from the "Tape Out" or "rec out" part of the amp.

what you are doing is rediculous though because you don't need your amplifier at all. Just go spend $20 or $30 on a 'pre-amp' and use that instead. it's the proper way to do what you want to do.

Turntables and microphones do not have a pre-amplified signal output like a CD player, cassette deck or DVD player ect. They require a pre-amplifier in order to generate a signal strong enough to be used by the amplifier.
Pre-amplifiers are quite small and very self-explainitory.
