Rolls RPB486 产品宣传页

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.

FRONT PANEL

The green LED for each channel lights when that channel is in use. All these 
LEDs light momentarily when the RPB486 is powered up.

The red PWR led indicates the unit is on.

REAR PANEL

120 VAC  50/60 HZ 15 VA: Power Cord. Connect to a properly grounded AC 
source.

NOTE: THE FOLLOWING DESCRIPTION APPLIES TO EACH OF THE SIX 
CHANNELS.
INPUT: Female balanced XLR jack - for connection to the condenser microphone. 
Pin 2 is hot. This jack carries the 48 volts of phantom power to the microphone.
OUTPUT: 1/4” Tip-Ring-Sleeve balanced jack - for connection to a mixer or multi-
track recorder. Note: If you are connecting this to a mixer, adjust the mixer’s gain
