Phono setting and MC/MM

Probably an older Mac, they would do MM, MC or MI. 3.5mv or better would work, load the MC cart correctly and away you go.
No your receiver is a MM cart.

The MC cart you have unless it's like a 5mv or higher. High output MC 

Look up the model number on the cart and see what the specs are. Google works great OP without a name and model. They are all different..

Thanks for all the replies.

He is looking to pick up a pioneer sx780.

The cartridge is a Japanese name (I don't have the box in front of me).  Pic below.

Looks like we will hook it up and see if we need that head amp.

The cartridge is a Hana SL low output and the Pioneer is absolutely not compatible for cartridges MC.

Ok, thanks!

I agree you won’t have enough gain, most likely, but it will hurt nothing to just hook it all up and give it a try. That will let you know where are you are starting from.
