Well, according to the PMB manual, it says it puts out slightly more than 9 volts when using the adapter but doesn't say how much. I guess one 9 volt supplies the phantom and the other 9 volts supply power to the rest of the unit. The PMB uses two nine volt batteries if you don't use the adapter. In researching, trying to find a replacement, which I guess just isn't possible, I've read that it's fairly common for these adapters to be fried, something about unplugging them while the unit is on or something. Anyway, I'll either use it with batteries or continue to use the K&K belt pack preamp. Interesting that the K&K only uses one 9 volt battery and it, too, supplies phantom for the mic.
