Marantz 2325 Phono section

Hi Goners,

I need help with info on the capabilities of this unit's phono section.
Since it was developed in the seventies i am assuming it was for mm carts only.

I am going to be using a Thorens 160s tt and would like to know if this will work with the existing "phono" inputs for mm only or should i invest in an outboard[Like the Benz] for mc/mm capabilities?

Lastly,if i go outboard what inputs should i be using?

Thanks to all for any help!
