Key Benefits

• Capture studio-quality vocals with UA’s flagship dynamic modeling microphone
• Harness the authentic sound of the most popular microphones ever made with Hemisphere mic modeling technology
• Get pristine recordings of vocals or instruments in any environment, from pro rooms to home studios
• Craft your perfect sound with ease using selectable low-cut filters and enhanced articulation boost to make vocals and instruments stand out

Record Through Five Famous Mics

SD-1 is powered by the same mic modeling technology found in Universal Audio’s award-winning UA Sphere microphones. With the included Hemisphere Mic Collection, it’s the only dynamic modeling mic that gives you the authentic sound of famous vocal and instrument mics from RCA, Beyerdynamic, Sennheiser, and more.*

A Modeling Mic That Works for You

SD-1 and the included Hemisphere Mic Collection plug-in work with or without UA hardware, and go way beyond subtle EQ curves to give you precise control over filter, proximity, and axis — an industry first. Just set up SD-1 and use the plug-in to find that “sweet spot” for vocals, or tame harsh frequencies on your instrument.

Get Natural Vocals in Any Environment

Universal Audio fine-tuned the cardioid polar pattern on SD-1 to easily reject background noises like fans, refrigerators, or noisy bandmates. So whether your setup is in a bedroom, rehearsal space, or pro studio — your close-miked speech and vocals will naturally pop through the mix, no muss no fuss.

Tailor Your Tone

The filter switches on SD-1 let you easily reduce low-end rumble for cleaner recordings, or add some presence to any source. And if you own an Apollo audio interface, you can audition and record through different mic models in realtime, plus use custom channel strip presets to get album-ready sound right out of the box.

Deck Out a Desktop Studio

SD-1’s sleek design and rear-mounted XLR jack make clean cable runs a breeze. And its built-in shockmount and windscreen will make your music recording, podcasts, livestreams, or Zoom meetings sound automatically cleaner.

 DN-7

Renowned for its use on high-profile records by everyone from Michael Jackson to Metallica, this ubiquitous cardioid dynamic mic can also be found in radio and broadcasting studios around the world.

This industry-standard broadcasting mic has applications ranging from vocals to kick drums. Its presence boost and high frequency dip minimize sibilance, and with the filter switch you can get additional tone shaping by cutting below 400 Hz.
