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.
High Pass Filter Switch
The Gemini II features a few improvements over the original Gemini. A high-pass filter switch is in place and eliminates low-frequency hum and noise.
-10dB Pad Switch A -10dB Pad switch has been added for attenuating microphone level when capturing excessively loud audio signals.
Dual Valve Design
The Gemini II features a twin valve design. A 12AX7 provides the warmth and detail on the input stage while a 12AU7 provides a transformer-less output stage.
Cardioid Polar Pattern
The fixed cardioid pattern rejects noise and ambiance at the off-axis sections of the capsule while.
Low Noise Floor
The Gemini's audio reproduction eliminates the ambient noise associated with most tube microphones.
Generous Cable Length
The Gemini II features a secure connection to the PSU and a generous long cable provides flexible placement.
