INTRODUCTION
Thank you for your purchase of the ROLLS RPB486 PHANTOM HEX 6 channel
phantom power supply. This unit powers up to 6 condenser microphones with 48
volts of ultra clean phantom power. The outputs are 1/4”Tip-Ring-Sleeve bal-
anced for easy connection to a digital multi-track recorder.
To eliminate the possibility of any DC voltages, the RPB486 features pull-down
resistors and isolation capacitors on all outputs.
