The Schoeps CB 140 IRT microphone cross is an arrangement for ambient recording. Its primary characteristic is a transparent and spacious rendering of the acoustic environment. It is useful as a four-channel arrangement for room tone (for example in combination with the OCT surround system).
The setup can also be used for full surround (e.g. 360° cinema sound recording) or for other playback arrangements in which the speakers are placed in the four corners of a square.
Microphones are spaced 140 mm apart.
