With Hemisphere Mic Modeling

The world’s most inspiring dynamic vocal mic.

Get natural-sounding vocal and instrument recordings with our SD-1, a classic dynamic mic with flat frequency response and onboard tone-shaping. With its cardioid polar pattern and best-in-class Hemisphere mic modeling, SD-1 gives you pro results, no matter where you record.



Record Through Five Famous Mics

SD-1 is powered by the same mic modeling technology found in our award-winning UA Sphere microphones. With the included Hemisphere Mic Collection software, 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.* See included mic models ›

      A Modeling Mic That Works for You

      SD-1 and the included Hemisphere Mic Collection software 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

      We 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.

      A good microphone for beginners.

      I used to have the SM7b, and when someone told me about this UA microphone, I bought it and now I sold the SM7b because this mic has so much to offer, good for vocals, snare and guitar amps. Love this mic.

      Apollo will hiss but I think it’s Apollo

      Read the hiss comment from Jin I think you can use the different preamp models on twin to be less noisy I think the initial pre amp but with a volt it’s like a vocalist dream in a bad room good rejection not like the d facto mic I just brought look in to that mic and ribbon mics change my world make mic placement easier too

      Is this what you expected?

      From the moment I made my purchase of this product, there was that fear, is this what I expected? After seeing many reviews, comments and multimedia files, I have come to the conclusion. It is not the same to see it, to listen to it through speakers, than to already have it in person and carry out tests. If it is everything I expected, even more I would say. such a versatile sound, so friendly to work with, 10/10 quality. I am a user of a UA VOLT 2 interface and they behave together in an unexpected way. It's a dynamic duo. In general terms, it is a product that you know from the first instance that you are facing a high quality product and premium materials. Without a doubt, a great ally for my future productions and with an exclusive flavor.

      All this is my humble opinion about this excellent product. Undoubtedly. It is my favorite dynamic microphone for a long time.

      Seriously impressive.

      Bought this to compare with its clear competitor the Shure SM-7b and I'm very satisfied with the quality this thing delivers. Using it for voiceover, podcast, and vocal recording. Blown away by the versatility and overall aesthetic of this microphone. My new go-to dynamic mic!

      Not good as my imagination

      I just directly plug it with Apollo twin x interface, and noise is shocking! I don't know how to deal with that so I decided to ask a refunding.
