The USM 69 i is a one-point stereo microphone for all coincident stereo techniques such as XY, MS and Blumlein. Both large-diaphragm capsule systems can be operated with 5 directional characteristics each. The upper system can be rotated up to 270°. The USM 69 i can also be used as a mono microphone with two polar patterns at the same time.

Features:

  • Stereo microphone for XY and MS stereophony
  • Two large membrane systems, individually switchable
  • Five polar patterns
  • The upper capsule can be rotated up to 270° compared to the lower one
  • Very low self-noise
