With the SD-3, Universal Audio offers a compact dynamic microphone designed to quickly achieve studio-like results on sources that require impact and control. While many "all-terrain" microphones focus on durability, the SD-3 aims for a more controlled signature, with classic cardioid directivity and a design oriented towards isolation-ideal when the environment is noisy or when the drum kit is close to amplifiers.
Its real asset within the UA range is the direct integration with Hemisphere, a modeling plug-in that extends the recording process beyond simple placement. You record cleanly, then choose the character that best fits the track, without swapping microphones multiple times or spending hours searching for "the" right compromise.
The Universal Audio SD-3 is aimed at demanding home studio users, studios seeking a reliable microphone for quick takes, and musicians who regularly record high-energy sources. On a snare drum or toms, it helps achieve a clear attack while retaining body. On a guitar cabinet, its short format facilitates placement close to the cone, even when access is limited by the stand, grille, or stage space.
Thanks to its cardioid directivity, the SD-3 is also suitable for contexts where separation is crucial: live sessions, recorded rehearsals, shared booths. It captures the essence of the source while limiting off-axis sounds, simplifying mixing and reducing the need for heavy processing.
The SD-3 comes with Hemisphere, a free plug-in based on the same approach as UA Sphere microphones. Practically, you can retrieve with one click colors inspired by iconic dynamic models (references often associated with Shure, Audix, and Sennheiser) and work "as if" you had multiple microphones at hand.
Hemisphere is not limited to changing EQ: you can refine the sound with parameters for filtering, proximity effect, and positioning (axis). Very useful for rescuing a take done in a hurry, adapting a snare to a new mixing context, or thickening an amp without adding artifices. The plug-in works in real time with Apollo or natively in your DAW, integrating seamlessly into your usual workflow.
Fully metal-built, with a selected capsule and refined finish, the SD-3 embraces a retro style while remaining designed for real-world constraints: transport, stage changes, multiple takes day after day. Its size (short and discreet) makes it particularly easy to position in dense setups, especially around a drum kit or in front of a combo amp.
