Phantom power supply box.
The Radial StageBug 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 StageBug SB-48 phantom power supply 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.
