SE Electronics Gemini 5 Tube Condenser Microphone. It is based on the popular Gemini/Gemini II platform, and shares a capsule and body styling with the earlier Gemini mics. Physically, the Gemini 5 looks like a smaller version of the Gemini II, but it is still a hefty microphone, featuring a cylindrical body machined from brass, with ventilation holes on the rear to help keep the circuitry cool.
The Gemini 5 is a large-diaphragm condenser microphone with an innovative dual amplifier circuit, in which both tube and FET amplifiers are simultaneously operational.
