The Neumann STH 100 Stereo Mount consists of a swivel mount and two holders, for two detached miniature microphone capsules. Two stereo recording methods are then possible.
One holder enables the microphone setup according to the "ORTF Method": Two detached capsules are snapped into the clamps at the end of the holder. The distance between diaphragms is then 170 mm, with an angle of 110°.
The other pair of holders allows stereo setups according to the "Coincidence Method": Capsules are installed acoustically at one point in space, however, freely adjustable to any angle between 30° and 180°.
The swivel mount has a 5/8"-27 thread, plus a thread adapter to connect to 1/2"- and 3/8" stands.
