Internal phono stages typically only accommodate moving magnet cartridges, which is what you have. There are no options for "loading" the cartridge or changing the gain for low output moving coil cartridges. Some higher end integrated amps will have some adjustments.
A good phono preamp will give you a wide range of options for loading, multiple gain settings, and overall much better sound quality than the one included in your Marantz.
With the turntable and cartridge you have now it probably doesn't matter that much, but if you are on a quest to improve the sound quality of your system it will at some point.
