Incredibly huge, detailed, and intimate

Gemini II

The Gemini II dual valve microphone is a no-holds-barred piece of microphone history. The dual valve design means pure valve warmth from the 12AX7 input valve, coupled with a 12AU7 valve on the output stage. The result is an incredibly large, detailed, and intimate sound – reminiscent of the classic valve microphones from decades ago, but with a thoroughly modern twist.

Inside the Gemini II

1/4" TRUE CONDENSER CAPSULE

The Gemini II has a 1/4" capsule handcrafted and individually tuned in our factory. Thanks to a larger-than-life capsule, true condenser technology and ultra-precision parts, the Gemini II delivers a sparkling, pristine high-end typically only found in the most expensive solid-state microphones, while maintaining the rich, thick tonality of a tube mic.

SWITCHABLE BASS-CUT AND PAD

Not just for vocals, the 150 Hz bass-cut filter and -10dB pad make the Gemini useful for loud and heavy sources like drum room mics and booming timpani.

DUAL VACUUM TUBE DESIGN

Most microphones use a transformer to optimize the mic's output impedance and couple the mic to the mic preamplifier. With the Gemini II, this optimization is accomplished with a second vacuum tube, negating any high-frequency roll-off typically incurred with a transformer.

HAND-MADE ALL-METAL HOUSING WITH GOLD XLR CONNECTOR

The Gemini II’s hand-made all-metal housing, gold-plated XLR connector and gold-sputtered diaphragms ensure maximum reliability in any and all sonic settings from studio to stage for years of demanding use.
