Marantz PM84 MkII as pre amp?

I recently managed to get hold of one of these and was wondering if it can be used as a pre amp with a NAD 214? On the back it has Pre Out and Main In sockets connected by a U shaped steel bar. Apologies if it's a simple question but I'm a bit of newbee to the world of pre/power having only use intergrateds before.
Any help appreciated.
