The Soyuz SU-011 Small Diaphragm Tube Condenser Microphone delivers sound as rich, warm, and beautiful as its handcrafted, polished design suggests. Swappable capsules make this high performance microphone at home in a wide range of critical instrumental, orchestral and choral recording applications.

Utilizing a NOS subminiature military spec tube, the SU-011’s silky sound fills a longtime void in the world of high-end pro audio.


The SU-011's tube and transformer based circuit and handmade capsule deliver classic tube warmth; its sound is well-balanced throughout the frequency spectrum with an open top end that is never harsh or brittle.
