Denecke PS-1A Microphone Power Supply

The Dcode? PS-1A is a low noise, Phantom 48 volt microphone power supply. The PS-1A works with one 9 volt battery and has enough power to run high current microphones. The small size, light-weight, rugged construction and very low noise make the PS-1A a natural for powering microphones feeding DAT machines, radio mics, tape machines, and mixing panels. Long battery life and a bright LED low battery indicator ensure that the microphone is properly powered during your recording session.
