Dual-tube Cardioid Condenser Microphone with 12AX7 Input Tube and 12AU7 Output Tube sE Electronics Gemini II Dual-tube design 12AX7 at input stage 12AU7 at output stage Brings you best of classic tube mic designs with solid state-style top-end Frequency Response: 20Hz-20KHz Sensitivity: 12.6mV/Pa – 38 +/- 1dB(0dB=1V/Pa 1000Hz) Polar Pattern: Cardioid Impedance: 200 Ohms Equivalent Noise Level: 12dB(A weighted) Max SPL for 0.5% THD@1000Hz: 135dB Power Requirement: External PSU included. Connector: 3-pin The Gemini II Dual Tube Microphone from sE Electronics 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 20 Hz to 20 kHz 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 3-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 SwitchThe 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. -10 dB Pad SwitchA -10 dB Pad switch has been added for attenuating microphone level when capturing excessively loud audio signals. Dual Valve DesignThe 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 PatternThe fixed cardioid pattern rejects noise and ambiance at the off-axis sections of the capsule while. Low Noise FloorThe Gemini’s audio reproduction eliminates the ambient noise associated with most tube microphones. Generous Cable LengthThe Gemini II features a secure connection to the PSU and a generous long cable provides flexible placement.
