Do I need anything additional to my setup for my pro-ject debut 3 turntable?

Complete amateur that inherited the below setup from my uncle:

2 floorstanding speakers -> McIntosh MC402

McIntosh MC 402 into Bel Canto DAC 3

I want to add my pro-ject debut 3 to this setup. Currently it is plugged into an integrated Marantz PM6004 that I would like to keep for a second setup.

Looking at my options, the McIntosh has a phono input but plugging in the turntable to it doesnt do anything. The Bel Canto DAC 3 doesn't really have an input option (optical and USB are being used for the TV, SPDIF and AES/EBU are digital so wouldn't work for the turntable?)

Any guidance would be great thank you
