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 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.
-10 dB Pad Switch
A -10 dB 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.
