  • Transformerless Dual Vacuum Tube Design Eliminates High-Frequency Rolloff From Transformer Coupling
  • Hand-Crafted 1.25-Inch True Condenser Capsule Individually Tuned For Sonic Precision
  • Gold-Sputtered Mylar Diaphragm And Hand-Made Metal Housing Ensure Long-Term Reliability
  • Switchable 150 Hz Low-Cut Filter And 10 dB Pad For Loud And Boomy Sources
  • Included Custom Shock-Mount, Power Supply, And Flight Case Support Immediate Studio And Stage Deployment

The Gemini II is engineered for professionals seeking authentic tube microphone character without vintage limitations. Its transformerless dual-tube design uses a 12AX7 input stage and 12AU7 output stage to deliver rich, warm tonality while preserving the sparkling high-end detail typically lost in transformer-coupled designs. The hand-crafted 1.25-inch true condenser capsule is individually tuned in sE's factory, providing the sensitivity and headroom demanded by touring engineers, session producers, and broadcast facilities.

Built for versatility across vocals, drum overheads, room mics, acoustic and electric guitar cabinets, orchestral strings, piano, and brass, the Gemini II handles demanding sources with a switchable 150 Hz bass-cut filter and -10 dB attenuation pad. Maximum SPL reaches 151 dB (pad off) and 135 dB (pad on), ensuring clean capture of loud and transient-rich sources. The gold-plated XLR connector, hand-made all-metal housing, and gold-sputtered mylar diaphragm withstand years of intensive studio and stage use.

Included shock-mount, power supply, and flight case protect your investment and enable rapid transport between sessions and venues. No phantom power required—the dedicated power supply unit eliminates dependency on preamp phantom voltage, a critical advantage in remote recording and touring environments.
