SontronicsZETA Large-Diaphragm JFET Condenser Microphone - Black

Capture the moment a performance comes alive without spending the rest of the session trying to manufacture its character. Hand-built in England, the Sontronics ZETA large-diaphragm condenser microphone pairs a high-sensitivity JFET design with a boutique Lundahl transformer to deliver a polished balance of clarity, warmth and musical detail from the moment you hit record. Its cardioid capsule provides a full 20Hz–20kHz frequency response and 33mV/Pa sensitivity, while an exceptionally low 9dB A-weighted noise floor preserves breaths, textures and subtle dynamics with a clean background. Smooth highs, rich mids and a naturally flattering overall response make the ZETA a versatile choice for vocals, voiceover, acoustic guitar, piano, strings and other sources where detail and character need to coexist. JFET Electronics Capture Fine Detail With Low Noise The high-sensitivity JFET architecture is designed to reproduce subtle changes in articulation and dynamics without requiring excessive preamp gain. With just 9dB A-weighted equivalent noise, this condenser keeps the electronic noise floor low when capturing intimate vocals, delicate acoustic instruments and other nuanced performances. Its cardioid polar pattern focuses pickup toward the source while reducing sound arriving from the rear, helping engineers achieve more controlled recordings across a variety of studio and room setups. Lundahl Transformer Adds Boutique Analog Character A premium Lundahl transformer brings a distinct musical quality to the signal path, complementing the microphone's modern precision with additional warmth and dimensionality. Rather than attempting to recreate a specific vintage microphone, ZETA is voiced with its own character: smooth through the upper frequencies, substantial through the mids and detailed across the spectrum. Maximum SPL handling of 125dB also gives this model enough headroom to move beyond quieter sources and capture stronger performances while retaining its polished tonal balance. Hand-Built in England for Professional Studio Work Each microphone is hand-built and tuned in England, combining boutique components with a modern black finish, engraved badges and gold accents. A standard 3-pin XLR output integrates with professional interfaces, mixers and microphone preamps, while 48V phantom power supplies the condenser electronics. Weighing approximately 1.5 lb. and measuring 7.5" x 2.1" x 2.1", the Sontronics ZETA brings high sensitivity, ultralow noise and transformer-based character together in a versatile studio microphone backed by the Sontronics Limited Lifetime Warranty.
