Question DEar Sir,
If you have a turntable and a tape deck,and hook up the turntable to the deck line-in directly can you do any album recordings? Or does the signal need to be AMPLIFIED first?
Answer The output from a truntable comes directly from the tone arm pickup. With a magnetic pickup, that is about 20 millivolts (0.020 volts). Line in signals are about 500 mV (0.50 volts). So, yes, you need an amplifier. This level of amplification is called a preamplifier (or preamp). 20 years ago, when turntables were still popular, you could buy an inexpensive preamp for this purpose. I don't know what is still available. I think that I might still have a full fature preamp, if you're interested. I would sell it for $50 plus shipping. If you would like to buy it, let me know by emailing me at david.nyce@mts.com.
