sE Electronics Gemini II Dual Valve Microphone

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.

Dual-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 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.
