Universal Audio SD-3

Universal Audio SD-3 is a professional dynamic microphone featuring Hemisphere mic modeling technology, enabling accurate emulation of legendary microphones from renowned manufacturers. With a cardioid polar pattern, wide frequency range of 40 Hz – 15 kHz, −58 dB sensitivity, and 250 Ω output impedance, it delivers precise sound capture and excellent off-axis rejection for a variety of studio and live applications.

Designed for guitar amps, snares, toms, and brass instruments, the SD-3 combines vintage tone with modern Hemisphere modeling flexibility. The included Hemisphere Mic Collection plugin provides access to five authentic mic models from Shure, Sennheiser, and Audix, offering classic studio tones in a single microphone. It also allows detailed control over proximity, EQ, and axis response, making it easy to dial in the perfect sound for any source.

The SD-3’s rugged all-metal build, compact size, and retro-inspired design make it ideal for close miking and tight recording spaces. Whether used in a bedroom studio, a professional control room, or on stage, the SD-3 ensures natural, punchy, and articulate sound reproduction worthy of the most trusted dynamic microphones in history.
