"I am incredibly impressed by the seemingly contradictory combination of warmth, crispness and definition that was captured in the tracks by the sE Gemini and Reflexion Filter Pro...the songs we were working on had dense arrangements yet the sax cut through without ever sounding abrasive or disconnected from the rest of the was a beautiful, natural sound -­ we didn't even use any EQ." - Don Was, Producer/Engineer (Bob Dylan, Bonnie Raitt, The Rolling Stones, Willie Nelson)

"Awesome mic. Killed my 251 on super-rich gospel vocals." - Chris Fogel, Scoring Engineer ('Wolf of Wall Street', 'The Secret Life of Walter Mitty', 'Old School')

"The transformerless design would appear to combine the most recognizable attributes of tube and solid-state microphones, providing the expected tube warmth and low-end weight but without losing the high-end sizzle, as can happen with 'tube plus transformer' designs. Because of its high-end clarity, the Gemini II also makes a useful instrument microphone, its capabilities extending from acoustic guitars and other plucked instruments to percussion and wind." - Paul White, Sound On Sound

The sE Gemini II is the larger-than-life answer to your vocal tracking needs.

It's not just large in stature - it's HUGE in sound.

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.


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 rolloff typically incurred with a transformer.

This provides the Gemini II with 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.

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

The Gemini II comes packaged in a wooden presentation box next to its custom shockmount and robust power supply, all within a secure and solid flight case.
