SCHOEPS ORTF-3D Indoor Set

Product overview

The SCHOEPS ORTF-3D Indoor Set is an eight-channel set with microphones for indoor ambience recording in 3D audio, built as a square array with 18 cm between the capsule centres.

At its centre is the CB ORTF-3D, a mechanical mount that holds eight microphones according to the ORTF-3D principle. It carries four CCM 41 L supercardioids and four side-addressed CCM 41V L supercardioids, and each microphone pair can be fitted with a WMS foam windshield.

As the official graphic shows, the four pairs sit at the corners of an 18 cm square, 90° apart in the horizontal plane; in the vertical plane one microphone of each pair is angled upwards (+60°) and one downwards (-30°). The official photos show the array on a stand and suspended from above. Instead of the CCM microphones, combinations of the CMC 1 L amplifier and an MK capsule are also suitable.
