: 90 – 160°
– good separation between the L/C and R/C sectors
– distance between microphones: 4 – 100 cm
– can be expanded for five-channel OCT surround
The OCT (Optimized Cardioid Triangle) is a well-
designed method for obtaining the front channels for
a convincing surround recording of music. A detailed
description of the OCT technique can be found on
page 132 in the technical appendix.
This 1-meter-long mounting bar has 3/8" threaded
attachments for three stand adapters or shock mounts
(not included). The microphones can be positioned
anywhere along the bar. Each side of the bar is en -
graved with markings every 2.5 cm so that distances
of 5 cm, 10 cm, 15 cm, etc. can easily be set between
the two outer microphones.
Please note: Stand adapters or shock mounts must be
ordered separately. Recommended stand clamps or
shock mounts: SG or A 20 for Colette-series micro-
phones (e.g. CMC); SGC or AC for CCM-series micro-
phones. A standard extension bar for the forward-
facing cardioid in OCT is included; a longer arm for
the OCT 2 variant is optional.
Thread: 3/8", length: 1000 mm, weight: 500 g
OCT Surround Setup (by Günther Theile, IRT Munich,
Germany)
– for recording five-channel surround
– the simplest and most compact arrangement for
surround recording with OCT
A complete OCT surround setup is obtained by adding
a mounting bracket (CB-MAB) along with a second
MAB 1000 stereo bar for the rear-channel microphones.
