mics > BB > AD20 > optical cable > iriver Is what I run when I run the AD20, which I haven't done in a long time. I just don't run the AD20 because of the "hiding" requirements. I should get it back out, I think it helps a good bit with the sound. My shows lately have been lacking, maybe I have been in crappy locations. I modded my AD20 to take the 1/8" input by pulling the XLR contacts out of the box replacing them with the mini jack. I got rid of 1 somewhat bulky cable that way. My plan now is to mod my AT853s that came from Sound Pros to have the mini XLRs so I can do an adaptor to go phantom with the Samson adaptors or 3 wire battery box, which I have yet to get all the parts for. I am not familiar with many power supplies, a lot of guys use more of an all in one that has phantom and outputs a digital signal instead of 2 seperate units.
