Open Box sE Electronics Gemini II Dual Valve Tube Microphone Level 1

Capturing performances with warmth, detail and control requires a microphone that can translate both character and precision. The sE Electronics Gemini II dual valve condenser microphone is designed for studio recording applications that demand a classic tube response with modern clarity. Its dual-tube architecture—featuring a 12AX7 input valve and a 12AU7 output stage—works in tandem with a handcrafted 1.4" true condenser capsule to deliver a full, detailed signal across a 20Hz–20kHz frequency range. With a cardioid polar pattern and high SPL handling up to 151dB, it is well suited for vocals, instruments and room capture, providing consistent performance across a wide range of recording scenarios.

Dual Valve Circuitry Delivers Balanced Warmth and Transient Detail

The Gemini II uses a dual-tube signal path to shape its response, combining the gain characteristics of the 12AX7 input valve with the output stage control of the 12AU7. This configuration supports a balanced signal with both harmonic depth and transient detail. A switchable -10dB pad allows the microphone to accommodate louder sources such as drum overheads and guitar cabinets, while the 150Hz low-cut filter helps reduce unwanted low-frequency buildup. Together, these controls give engineers flexibility when adapting the mic to different recording environments.

Handcrafted Capsule and Low-Noise Design

At the core of the Gemini II is a hand-crafted 1.4" true condenser capsule with gold-sputtered diaphragms, designed for consistent sensitivity and detailed capture. The solid metal housing provides durability for daily studio use while helping shield internal components from external interference. With a low self-noise rating of 13dB and a wide dynamic range, the microphone maintains clarity across both subtle and high-energy performances, supporting clean signal capture in a variety of recording situations.

Integrated Power Supply and Cardioid Pattern

Designed for professional recording environments, the Gemini II includes a dedicated power supply, custom shock mount and multi-pin cable for stable operation and straightforward setup. Its cardioid pickup pattern focuses on the source while minimizing off-axis noise, making it effective for vocals, acoustic instruments and room applications. With its combination of tube-driven character, controlled response and adaptable features, the sE Electronics Gemini II dual valve condenser microphone provides a reliable solution for engineers seeking consistent, detailed results across a range of studio workflows.
