Rolls PB23
48V Phantom Power Supply


The Rolls PB23 is for powering phantom powered microphones with either 12VDC or 48VDC. Since the unit uses a 100kHz switching power supply, there is no audio noise generated. It has output pull down resistors so it will work with any mixer, and has two DC jacks so several units can use one adapter. The PB23 powers one microphone.
