Gemini II Large Diaphragm Dual Tube Cardioid Condenser Microphone

sE Electronics Gemini II Dual Tube Cardioid Condenser Microphone with High Pass Filter and -10dB Pad


SE-Electronics takes a unique approach in the design of their flagship tube microphone, the Gemini II. Gemini II is designed for crucial capturing of vocals and instruments in professional recording applications and features a unique dual tube design. The SE-Electronics twin triode valves feature a 12AX7 (ECC83) and 12AU7 (ECC82) tubes that provide pristine warmth and detail at the input and output stages of the microphone.

The Gemini II maintains a low noise floor, minimizing the "room noise" associated with most tube microphones. The capsule houses a large diaphragm cardioid element that features a wide 20Hz to 20kHz frequency response. The cardioid polar pattern is flexible for most applications as it rejects ambiance and noise at the off-axis sections of the capsule. The Gemini II uses an external Power Supply Unit (PSU) and an 8-pin screw-on terminal ensures a secure connection from the microphone to the PSU. A generous 13 foot (4.2 meter) cable is supplied for flexible placement and a heavy duty, wooden storage case is also supplied.
