PB23 MIC POWER I
6/04
The PB23 is for powering a phantom powered
microphone with a solid 48 VDC. The unit uses a
100kHz switching power supply to eliminate noise
generated by common power supplies. The PB23
has pull-down resistors so it will work with any
mixer.
INTRODUCTION
Thank you for purchasing the PB23 Mic Power I 48 Volt Phantom
Power Supply. This unit is designed and manufactured to provide 48
volts of clean dc power for your favorite condenser microphone.
Powered microphones provide much greater dynamic range, lower
noise, and better sound quality.
OPERATION
Connect a condenser microphone to a three conductor XLR cable,
and to the Input connector on the PB23. Connect the PB23 Output
to a mixer or other audio input device via another XLR cable.
Apply power to the unit by connecting the enclosed adapter to an
AC outlet and to the 12VDC Power jack. The LED on the front of the
unit will light. The PB23 provides no audio gain as it is not a
microphone preamp.
