Cardioid Condenser Microphone

The SU-019, introduced in 2016, is a large-diaphragm FET condenser microphone. It is physically — though not electronically — identical to the flagship SU-017 tube microphone. This means the two microphones share the same capsule, detachable capsule system, body dimensions and shockmount.

Electronically, the SU-019 is driven by FET topology where the SU-017 is a tube mic with external power supply.

Though the capsule head is detachable, the SU-019 is sold with a single large-diaphragm cardioid capsule head. The amplifier section (that is, the microphone body) can be used with a variety of other heads, including planned omni and figure-8 heads from Soyuz, as well as the small-diaphragm capsules from the company’s SU-011 pencil mic.

The SU-019 has a toroidal output transformer that Soyuz winds in-house.

The mic’s large-diaphragm capsule is based on the design of the Neumann K67; it is a dual-backplate, 34mm O.D. design with the K67’s characteristic drilling pattern.

The physical design of the SU-019’s body is based on mathematical principles. It is essentially a solid brass sphere, bisected and separated by a Golden Ratio… [T]he cylinder of the mic’s body has a ratio of 1 to 1.618. The exact size and distance of the capsule head is also based on the Golden Ratio. The designers of the SU-019 believe that using shapes and ratios that are favored by nature help to reduce unpleasant resonance.

The mic’s heavy brass body parts are milled and machined in house. They are not treated or coated; SU-019 owners will need to periodically clean them to retain their appearance. The microphone includes a polishing cloth for this purpose.

The SU-019 is packed in a wooden box, inside a larger cardboard shipping box which also holds the mic’s shockmount. The package includes a card signed by the individual technician who assembled the microphone.

According to Soyuz Microphones, Figure-8 and Omni capsule heads are in development.
