Aston Stealth. The Aston Stealth is a revolutionary broadcast quality microphone for studio and stage, with 4 switchable voices, delivering unparalleled performance in almost any situation. Stealth is the world’s first microphone with an autodetect function which senses 48V phantom power and automatically switches the mic to active mode. A built-in, high quality, Class A Mic Preamp dispenses with the need for an external gain lifting device in active mode. Stealth also features a unique Sorbothane internal shock mount system and Aston’s legendary build quality. With so many cutting-edge features and being suitable for almost every conceivable application, we believe Stealth is the world’s most versatile microphone.
