RADIAL StageBug SB-48UB Phantom Power Supply

The challenge when using a condenser microphone with a preamp pedal, direct box or stage amp is that most of these only have unbalanced inputs. And as most phantom power supplies are only equipped with balanced inputs and outputs, making a proper connection is often difficult or impossible due to the impedance and level mismatch. 

The SB-48UB is a single channel phantom power generator that converts the power from a 15VDC supply to 48 Volts for use with a condenser microphone or active direct box. Inside, the SB48-UB converts the signal to both a lo-Z balanced XLR output and a hi-Z unbalanced ¼" out. Both outputs may be used concurrently whereby the XLR could feed the PA while the ¼" out could feed a stage amp or pedalboard
