Karaoke setup help

Hi I need help setting up my karaoke system to an at home surround sound system.

HS is a Denon AVR X2300

Karaoke machine Phenyx Pro PTU-7000

Mixer Pyle PTA66BT

TV Samsung Smart TV

What do I need to do to get everything connected and working. I’m not technical inclined at all

Any help would be greatly appreciated.
