sE Electronics Gemini II: Where Vintage Warmth and Modern Clarity Meet
The SE Electronics Gemini II breaks with the tradition that tube microphones always have a “dark” or “limited” high. Thanks to its revolutionary dual tube design, the Gemini II is able to deliver a solid, warm low and midrange, while the high remains sparkling and detailed. The result is a sound so rich and finished, you hardly need EQ in the mix.
The Secret: Two Tubes for the Perfect Sound
Most tube microphones use one tube and a transformer at the output. The Gemini II replaces the transformer with a second tube:
Input Stage (12AX7): Provides that classic, rich tube warmth and harmonic saturation at the beginning of the signal chain.
Output Stage (12AU7): Takes over the role of the transformer. This provides a much wider bandwidth in the highs and an extremely low noise floor.
Hand built Precision
The heart of the Gemini II is the large, hand-built 1.07″ capsule. Each capsule is handcrafted and individually tested at sE’s factory. Combined with carefully selected tubes, this produces a microphone that captures even the subtlest nuances in a voice or instrument.
Professional Features:
External Power Supply Included: The Gemini II comes with a rugged, external power supply unit that provides stable voltage to the tubes.
Low-Cut Filter & Pad: Switchable settings on the microphone itself offer control over low-frequency rumble and protect against clipping at louder sources.
Rugged Chassis: The microphone is not only a technical marvel, but also a visual statement in any studio, built to last for generations.
Complete Set: Supplied in a deluxe wooden case, including a professional shockmount and a sturdy aluminum flight case for safe transport.
Who is the Gemini II for?
The Gemini II is the first choice for top producers working with vocalists who require a “big” sound. Although it excels on vocals, it is also insane on acoustic guitars, piano and even as a room mic for drums.
