OCT-3D SetRecording technique for 9ch Surround OCT-3D Set
The set contains:
optional: 4 * support rods STR 250.
These support rods serve to create a space between the lower and upper level microphones. This reduces their correlation in the diffuse field. Since the correlation in the diffuse field plays a smaller role in vertical pairs of speakers than in horizontal, the 4 Supercardioids for the vertical channels can also be mounted directly on the stereo bars.
