In order to connect various video and audio components to a speaker you generally need a receiver. It has inputs for the different components and an output for the speakers. The receiver allows you to connect your turntable, record player, CD player, TV, etc.

Can you plug a turntable into AUX?

Plug a turntable into an aux input and you may not hear anything even with the volume maxed. The reverse is also true – plug something that isnt a turntable into the phono input and the signal will be so strong it may well blow your speakers. Make sure the phono pre-amp is compatible with your cartridge.
