The Radial StageBug SB-48 is the perfect solution for musicians, sound engineers, and studio users who need a reliable, portable phantom power source. This compact unit provides stable phantom power for condenser microphones and active DI boxes – even in setups without built-in phantom power.
The StageBug SB-48 offers selectable 12V or 48V phantom power, making it ideal even for specialty microphones that require only 12V. A recessed side switch allows users to easily set the voltage. A “set and forget” design that prevents accidental changes.

With two independent channels, the SB-48 can power two microphones or DI boxes simultaneously. XLR inputs and outputs are wired to AES standards for maximum compatibility. A 15V DC power adapter is included, delivering dependable power. An LED indicator shows at a glance when the unit is active. The cable clamp secures the power cord against accidental unplugging, while the non-slip chassis provides a stable grip on any surface. Slim and lightweight, the SB-48 fits easily into any gig bag or rack.
The StageBug SB-48 is especially valuable in live environments where mixers or interfaces lack phantom power. It also safeguards sensitive microphones from voltage spikes and ensures stable, interference-free connections in any setup.
Doesn't make any damages to original sound, easy to recommend this one. Before this i tried couple similar products from other manufacturers in same price range and this one is first that kept original sound clean, tested with high-end vocal microphone.
