Universal Audio SD-1｜Flagship Dynamic Microphone｜UA Hemisphere Mic Modeling
Universal Audio SD-1 is a professional dynamic microphone designed for vocals, instruments, podcasts, live streaming, and studio recording. Equipped with UA’s Hemisphere Mic Modeling technology, it recreates the tonal characteristics of legendary dynamic microphones — including iconic models such as DN-7, DN-20, RB-77DX, DN-88, and DN-441 — giving you true broadcast-quality sound for any production.
Record Through Five Legendary Sounds
SD-1 is powered by the same mic modeling technology found in UA’s award-winning Sphere microphones. With the included Hemisphere Mic Collection software, you can instantly access five classic dynamic mic tones from RCA, Beyerdynamic, and Sennheiser. Capture authentic studio character that’s ready for any voice or instrument, right out of the box.
A Modeling Mic That Works for You
SD-1 and the Hemisphere Mic Collection software work seamlessly with or without UA hardware, giving you precision control over filter, proximity, and axis — an industry-first feature for dynamic microphones. Whether you’re shaping a podcast voice, controlling low-end rumble, or taming harsh frequencies on a guitar amp, SD-1 makes every take sound polished and professional.
Get Natural Vocals in Any Environment
The cardioid polar pattern on SD-1 is finely tuned to reject unwanted background noise — such as air conditioners, fans, or room reflections — making it ideal for untreated rooms, rehearsal spaces, and home studios alike. Your voice will cut through the mix with clarity and presence, without extra processing or fuss.
Tailor Your Tone
SD-1 features switchable low-cut and articulation boost filters that let you easily shape your tone for any situation — tighten the low end, add vocal sparkle, or balance your sound for instruments. Pair SD-1 with a UA Apollo interface to unlock real-time mic model auditioning and custom channel strip presets, giving you an album-ready sound the moment you hit record.
Deck Out a Desktop Studio
With its sleek design and rear-mounted XLR jack, SD-1 keeps your workspace tidy and professional. The built-in shock mount and windscreen make it perfect for music recording, podcasting, livestreaming, or Zoom meetings, ensuring clean, noise-free audio that looks as good as it sounds.
