That Yamaha AV receiver does not come with a built-in turntable/phono preamp. To use a turntable with that model receiver it will need a turntable preamp to amplify the signal. Phono line levels typically range from 2-5mV. The line level inputs on the receiver want to see at least 150mV. So it will need the preamp to amplify the signal.
For information on purchasing a turntable preamp, consult a local Yamaha dealer or local electronics shop.
