Can I connect a turntable to my Network Player?

Your Network Player doesn't have any analogue inputs or a built-in phono stage. There is, therefore, no way to directly connect a turntable to the device.

You should, however, be able to connect your turntable directly to an analogue RCA input or phono input on your connected amplifier, depending on whether your turntable has its own built-in phono stage.
