Cardioid Condenser Microphone

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

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

Though the capsule head is detachable, the 017 FET 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 (now discontinued).

The 017 FET 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.

(Please note that company quotes reflect the mic’s previous name)

The mic’s heavy brass body parts are milled and machined in house. They are not treated or coated; 017 FET owners will need to periodically clean them to retain their appearance. The microphone includes a polishing cloth for this purpose.

The 017 FET 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.

The 017 FET was previously called the SU-019.

The Soyuz Microphones 017 FET is also known as: 017FET, SU-019.

The mic was released in 2016.
