Ribbon Microphone

Vintage Inspired

Designed in collaboration with Stephen Sank, the prefix JRS pays homage to the late Jon R. Sank, who was known for his work with RCA that produced legendary microphones.

Built upon the shoulders of giant RCA mics, each JRS-34 ribbon is cut, corrugated and installed by hand.

Modern Electronics

Custom CineMag transformers, a patented round magnet, and Cloudlifter JFET technology expand the JRS-34’s performance for today’s applications.

Active Output

The active JRS-34 requires phantom power and has an output level compatible with virtually any modern preamp.

Made in the USA
