That is only half correct. In fact, one works with a cinch cable. However, this must be connected to the special "phono (MM) input" because record players have a much lower level. With normal line-in inputs, you hear far too little.

You need a cinch cable (red / white). You can connect this to the receiver at the rear at Audio IN (top left when viewed from the rear, 2nd or 3rd connection from the left). The inputs are called Cable or MediaPlayer. Personally, I would use the MediaPlayer channel, i.e. the 3rd connection from the left.

Then simply select MediaPlayer Source and enjoy the music.
