SE GEMINI-II Dual Tube Cardiod Condenser Mic With Shockmount and Case

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.

Dual Tube design, input tube is a 12AX7 and output tube is a 12AU7. Bass cut filter and -10db pad. Hand crafted true condenser capsule. 35mm gold/mylar diaphragm. Cardiod directional pattern. 20hz to 20khz frequency range with 35.48mV/Pa (-29db) sensitivity. 135/145 Max SPL and 75 db signal to noise ratio. 19 db self noise, 150hz pass filter switch, an -10db preattenuation pad. Dedicated power supply unit included
