Can the phantom power on a UA-5 be switched off/on? Just purchased a UA-5 off ebay and I already own an AT822 stereo mic that is battery powered. If I plug the AT822 in to the UA-5 with phantom power I risk damaging the mic. I will buy new mics soon, but for now I want to use the AT822 for matrix recordings with my JB3 or laptop. Thanks for your input!
