SCHOEPS OCT-3D Set

Product overview

The SCHOEPS OCT-3D Set is a nine-channel set with microphones and stereo bars for immersive recordings with the OCT-3D technique, made for the 5.1.4 format.

OCT-3D extends the well-known OCT Surround technique by four height channels. The OCT technique stands for natural surround sound, balanced imaging, high stability, high channel separation, high decorrelation in the diffuse field and high suppression of direct sound in the surround and height channels.

The set contains six CCM 41 L supercardioids, three CCM 4 L cardioids and two MAB 1000 stereo bars with additional riders for the height channels, the CB-MAB and a case. Optional STR 250 support rods create space between the lower and upper microphones, which reduces their correlation in the diffuse field; because this correlation matters less for vertical than for horizontal loudspeaker pairs, the four height supercardioids can also be mounted directly on the stereo bars.

SCHOEPS OCT-3D Set: frequently asked questions

What is OCT-3D?

A recording technique for the 5.1.4 format that extends OCT Surround by four height channels.

Which microphones are included?

Six CCM 41 L supercardioids and three CCM 4 L cardioids, nine microphones in all.

What are the STR 250 support rods for?

They raise the upper microphones above the lower ones, which reduces their correlation in the diffuse field. The four height supercardioids can also be mounted directly on the stereo bars.

Can I use Colette microphones instead of the CCM?

Yes. Combinations of the CMC 1 L amplifier and an MK capsule are also suitable, and the set can be ordered in this modular form.

Where can I buy the SCHOEPS OCT-3D Set in India?

The SCHOEPS OCT-3D Set is available from Shivansh Electronics, Kolkata, West Bengal, India, with delivery across India.

Workflow 1: OCT-3D with raised height layer

Engineers recording concerts for 5.1.4 playback.

Connections

Setup

1. Build the OCT front and surround layer on the two stereo bars.
2. Mount the four height supercardioids on the STR 250 support rods, facing upwards.
3. Route all nine channels to separate tracks.

Tip: The space between the layers reduces their correlation in the diffuse field.

Workflow 2: Compact OCT-3D on the bars

Recordists who need a smaller setup.

Connections

Setup

1. Mount the four height supercardioids directly above the lower microphones on the bars.
2. Check the orientation of every microphone.
3. Record the nine channels.

Tip: Correlation matters less for vertical than for horizontal loudspeaker pairs, so this compact form also works.
