I get these confused, but the 'old' XLR mic
adapter was the MA100. There are two new
flavors; the MA200 and MA300. The MA200 ($350) has
four XLR connectors and allows for the duel
battery charger to be attached, *or* you can
use it to attach an external wireless or
big battery.

I think the MA300($250) is for the GL2, but *might*
work with the XL1s. It has only two XLRs like
the MA100

None of the above provides phantom power for
condenser microphones, so as you suggest,
I personally would buy/bring along a mixer.

Murray,
The MA-300 is the XLR adapter specifically for the GL-2 camera. It connects to that camera's "Smart Shoe". (Personally, I prefer to use a BeachTek for XLR connections to my GL-2.)
