Overview

Vacuum Tube Ribbon Microphone

The R-122V is the pinnacle of our R-Series line, a world class tube ribbon microphone exhibiting unparalleled richness, depth and detail, particularly in the midrange frequencies. With a lushness that has to be heard to be truly appreciated, the R-122V offers the ultimate in ribbon microphone performance for those who insist on the very best.

The R-122V takes the Royer-pioneered concept of active ribbon microphone technology to an unprecedented level by incorporating vacuum tube electronics into the same proven transducer system used in the venerable R-121 and R-122 ribbon microphones. The high operating voltage of the vacuum tube provides headroom far beyond that available from a standard phantom power supply. Sonically this translates into unmatched clarity, detail and airiness, along with the ability to handle brute SPL levels without flinching.

Product Details

  • Vacuum tube electronics provide high output capability, optimal impedance to the ribbon element and low output impedance
  • Extremely low self-noise
  • Operates from a dedicated power supply
  • High SPL capabilities for electric guitar and percussion instruments
