Cloud Microphones JRS-34-P Ribbon Microphone

The Cloud Microphones JRS-34-P is a passive ribbon microphone with bi-directional polarity. It combines all the best features of vintage ribbon microphones of the RCA44a and RCA BK-11a.

The Cloud Microphones JRS-34-P is designed by Stephen Sank, son of legendary RCA microphone designer Jon R. Sank. The JRS-34 brings this RCA heritage into the 21st century with modern technology. A brand new suspended shock-mounting system use a suspended ribbon mounted on springs. Two of the nickel plated springs carry the signal to the output circuit through output cables.

The ribbon element is of specially tampered 1.8 micron pure aluminium. It is cut and corrugated to match the ribbon used in the RCA 44a. The ribbon motor uses rounded magnets to reduce the amount of reflected sound. This technique avoids waves reflections and comb filtering colouration.

Handmade in the US, the JRS-34-P exhudes class and only used high-quality components.
