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

The Radial SB-48 is a high performance phantom power generator that employs a non-radiating charge pump circuit to create a stable, ripple-free 48 volt supply for active direct boxes and condenser microphones. The stereo design features XLR inputs and outputs with a choice of 48V and 12V operation. The SB-48 is powered by a single 15VDC 400 milliamp supply that is included. The connector may be locked into place using a retention clamp. As with all Radial products, the SB-48 is manufactured in Canada from solid steel and powder coated for years of great looks! |
The APT20 is a phantom power supply unit for use with two condenser microphones. It supplies 48 V DC to the microphones and routes the signal to a mixer or microphone amplifier. It features XLR connections for in- and output, and at the back is an euro power connection with power switch provided. ![]()
