Stereo Recording Made Easy
The USM 69 i is a one-point stereo microphone for all coincident stereo techniques such as XY, MS, and Blumlein. Each of the two large diaphragm capsule systems has its own pattern selector with 5 positions; the upper system can be rotated over a range of 270°. The USM 69 i can also be used in mono with two directional characteristics
