Rolls PB223 Mic Power II Phantom Power Supply
The PB223 is for powering phantom powered microphones with 48VDC. Since the unit uses a 100KHz switching power supply there is no audio noise generated. The PB223 has output pull down resistors so it will work with any mixer. The PB223 is identical to the PB23, except it powers two microphones rather than one.
