Neumann USM69 I MT, Stereo microphone with two multi-pattern K 67 capsules

The Neumann USM69 I MT is a one-point stereo microphone for all coincident stereo techniques such as XY, MS, and Blumlein. Each of the two large diaphragm of the Neumann USM69 I MT capsule systems has its own pattern selector with 5 positions; the upper sytem of the Neumann USM69 I MT can be rotated over a range of 270 degrees. The Neumann USM69 I MT can also be used in mono with two directional characteristics simultaneously. 

Also, the Neumann USM69 I MT has two separate dual diaphragm condenser capsules, mounted vertically, which may be rotated againts each other over an angle of 270 degrees. The polar pattern of each Neumann USM69 I MT capsule can be selected individually using two built-in rotary switches. Each capsules has its own head amplifier that feeding separate pins of the XLR 5 output connector. Neumann USM69 I MT has two independent microphones in one convenient package. As it requires only one micrphone stand, the Neumann USM69 I MT is very easy to re-position for optimal results. With five polar patterns available for each capsule – omni, wide cardioid, cardioid, hypercardioid, and figure-8 – the USM 69 i allows for MS and XY stereo techniques in all variations, including Blumlein. Thanks to its low self-noise of 13 dB-A and its high SPL capability of 132 dB, the USM 69 i may be placed freely for best sound and imaging, with no worries about excess noise or distortion. An active subsonic filter protects the output transformers from overload due to structure borne noise.

The Neumann USM69 I MT is an excellent stereo microphone for any musical applications such as vocal and instrumental ensembles, drums overheads, large instruments such as grand piano and harp, as well as solo instruments when stereo width and spatial movement is desired to enhance the listening experience. The Neumann USM69 I MT is also a superb microphone for radio drama, and audio book productions with a sound similar to the acclaimed standard for spoken word, the Neumann U 87 Ai, but adding a stereo perspective. Apart from stereo applications, the Neumann USM69 I MT may also be used to record a mono source with two different polar patterns simultaneously. Since both microphones inside the Neumann USM69 I MT work completely independently, it can serve as its own backup microphone in high reliability situations. If one side fails or is inadvertently disconnected, the other side remains unaffected. Even in the rare event that DC converter for the capsule bias fails, the Neumann USM69 I MT remains operational; both systems will automatically select the cardioid pattern and continue to work with just a slightly reduced sensitivity.
