Studio condenser microphones sound really good for vocals, drums, and other acoustic instruments. But what if your mixer doesn't provide the phantom power you need to unlock their magic? The ultra-compact MICRO PS400 can solve all that and is small enough to fit in your pocket. The PS400 features XLR thru jacks and offers excellent interference-free operation. Simply connect your condenser microphone to the mic input and send a line from the mic thru to your mixer. You can switch between +12 V and +48 V power, depending on the operating voltage your microphone prefers. This handy little audio solution comes with its own 12 V DC power supply and an LED that indicates when it is turned on.
