You can use XLR x 2 -> 1/8" stereo, but you'll likely overload or brickwall the D8. You can make some homemade attenuators, if you're handy with a soldering iron for about $5-$10 in parts from radio shack. I made one that has 1/4" inputs and RCA outputs. To do a board tape, I then use XLR-> 1/4" cables to the attenuator box, and then a RCA -> 1/8" cable to the D8.
