Hi, Steve. Let me try to answer your questions. 1. The at 822 is the mic with the rol-off switch, the first mic you had that got stolen. This mic only, and I underline the word only, accepts battery power, so don't use it with phantom power. The second mic is the at 825, which I think also has a roll-off switch which is recessed. This mic can use either phantom or battery power. 2. As I said before, the 822 cannot accept phantom power. The 825 which I think is the mic you have now, can use either. If you're going to be using this mic with phantom power you dont need to have the battery in it. I think this mic can use 24 volqs of phantom, but you would have to test this. 3. If you use phantom power you do not need the battery. The battery is an alternative power source when phantom power is not available. 4. Phantom power is completely different than plug-in power. Phantom power requires from 12 to 48 volts, where as plug-in power requires from 1.5 to 9 volts. To use one of these mics with the new digital recorders such as the edirol or the zoom h 1 you need to have a battery in the microphone, unless the particular recorder supplies phantom power, like the zoom h 2. Hope this helps. On Mon, 11 Oct 2010 13:36:32 -0400, Steve Matzura wrote:
