OCT-3D Set

Recording technique for 9ch Surround

Features

  • 9-channel set for immersive recordings using “OCT-3D” technology with microphones and stereo tracks
  • OCT-3D is a recording technology for the 5.1.4 format (e.g. Dolby Atmos or Auro-3D), see Dolby Atmos Routing Guide 
  • OCT-3D extends the well-known OCT surround technology by four height channels
  • Features of OCT technology: Natural surround sound, balanced imaging, high stability, high channel separation, high decorrelation in the diffuse field, high direct signal suppression in the surround and height channels

Order number

  • No. 129005

Description

The set contains:

  • 6 * CCM 41 L, Supercardioid Microphones
  • 3 * CCM 4 L, Cardioid Microphones
  • 2 * MAB 1000, Stereo bars with additional riders for the height channels + CB-MAB + case

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...

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.

The CCM microphones can be replaced with the corresponding combinations of CMC 1 L amplifier and MK capsule.

Variants & Options

Instead of the CCM microphones, microphones consisting of a CMC 1 L amplifier and an MK capsule are also suitable. The OCT-3D Set can alternatively be ordered in this modular form.
