I operate a Dual DT 230 BT turntable with Bluetooth on my Melody CR612.... Sounds simply phenomenal. The Bluetooth transmission is reliable and clean.

i think that's possible. i have the cd player connected.

No, the M-CR612 Melody X does not have a phono input. However, there are some turntables that have an integrated phono preamplifier; only these models can be connected.

However, there are products from Marantz that can do it better and don't cost much more, e.g. this one has a record player input.

Marantz NR1200 (Stereo, FM, DAB+)

Yes! The connection of an analogue or digital device is possible.
