Are you trying to connect a TurnTable to the A/V Receiver?
This Receiver does not have a PHONO input jack.
Standard turntables that do not have a built-in pre-amplifier require a specific amplified PHONO input on the A/V receiver in order to operate correctly.
If the A/V receiver does not have a PHONO input and the turntable is connected either through an AUX or audio input, the turntable signal will need amplification from an external pre-amplifier (or an inline amplifier).
Without amplification of the turntable signal, low or no audio will occur.
NOTE: Sony does not produce a stand-alone turntable pre-amplifier. You may wish to check with your local Dealer for further assistance.
