i had a channel that would not phantom power when i got the unit from doug, but he pretty much determined it was a factory issue, and corrected it for me. only thing i'd say is power it up before you fly to nashvegas and want to use it, to make sure it works. i was able to run the board for the show in question and it did not affect the sbd input. running through the xlr's gets the benefit of the mod. it is my back-up/low pro/ bit bucket deck. a warm mod hdp2 is my main, and i love the warm mod. it mimics a 118/148 per doug. later
