Schoeps ORTF Surround Indoor Set

The “ORTF Surround” recording method is a new system for the pickup of surround ambience. This microphone arrangement and its sonic characteristics are quite similar to those of the well-known “IRT Cross“ designed by Gunther Theile. Both the 360° imaging and the spatial impression are of optimal quality. This is achieved with a high degree of signal separation among channels, based both on arrival-time differences and level differences.

The ORTF Surround Indoor Set comprises:

• 4 CCM 41 L, supercardioid compact microphones
• ORTF Surround Bar LM: a four-way “ORTF Surround Bar“ terminated with a Surround multi-pin connector (AES-65)
• Rycote Invision INV-7: an elastic suspension
• K Surround 5 M: a 5-meter, four-way Binder multi-core cable
• AK Surround M/4U: an adapter cable (Multipin / 4 ? XLR-3M)

When working indoors, the ORTF Surround Indoor Set is used without windscreen. If a moderate degree of wind protection should be required, a B 5 D foam windscreen can be placed over each microphone separately.
