The Universal Audio SD-3 is a cardioid dynamic microphone designed for capturing loud, detailed sound sources with clarity and precision. Its robust all-metal build and retro styling make it suitable for both studio and live environments. Powered by UA’s Hemisphere microphone modeling technology, the SD-3 allows users to emulate the sound of classic dynamic microphones from leading brands. This provides flexible tonal shaping directly within the recording workflow or DAW. With high SPL handling, strong off-axis rejection, and compact size, the SD-3 is ideal for close-miking instruments like snare drums, guitar cabinets, brass, and percussion, delivering focused and mix-ready results.
