Rolls PB223 - Manual (Page 2)

INTRODUCTION
Thank you for purchasing the PB223 Mic Power II Dual 48 Volt Phantom
Power Supply. This unit is designed and manufactured to provide 48
volts of clean dc power for two of your favorite condenser microphones.
Powered microphones provide much greater dynamic range, lower noise,
and better sound quality.
OPERATION
As shown in Figure 1, connect the two condenser microphones to three
conductor XLR cables, and to each Input connector on the PB223. Con-
nect the PB223 Outputs to a mixer or other audio input devices via other
XLR cables.
Make sure the Rolls PS27 adapter is connected to an AC outlet and to
the 12VDC input. The LED on the front of the unit will light when power
is applied. The PB223 provides no audio gain as it is not a microphone
preamp.
