Radio Design Labs ST-MPA2 Stick-On Dual Mic Phantom Adapter

The Radio Design Labs ST‑MPA2 Stick‑On Dual Mic Phantom Adapter is a compact and highly flexible audio accessory designed to bring phantom power support to standard microphone inputs in professional A/V installations. Whether you’re working with condenser microphones that require phantom power or integrating high-quality mics into mixers and interfaces that don’t natively supply it, this adapter converts existing mic inputs into phantom-powered inputs with ease. Its sleek, low-profile stick-on design makes it perfect for discreet placement in racks, under desks, podiums, or other space-constrained environments.

Engineered with reliability in mind, the ST-MPA2 features dual phantom power circuits that let you support two microphones simultaneously, providing highly filtered, adjustable phantom voltage that maintains audio integrity without introducing noise or distortion. This makes it especially useful in houses of worship, broadcast facilities, conference venues, and permanent installs where professional-grade mic power is needed but traditional phantom power sources are unavailable or inconvenient. A practical and robust solution for enhancing your mic input capabilities, the ST-MPA2 delivers clean, dependable phantom power exactly where it’s needed
