Conference Equipment Central Unit

The Sennheiser SDC-8200-CU-M central unit is the heart of Sennheiser’s SDC 8200 digital conference and interpretation system. All settings for the system are made via the central unit’s local configuration menu. Accommodated in a 19” full-metal housing, the SDC 8200 CU-M powers up to 50 conference terminals in six cable lines.

The SDC8200CU-M can handle up to 4 languages. The central unit features two analog audio inputs, e.g. for wireless microphones, and an analog audio output for recording units or an additional public address system. An IR modulator (4-channel operation) such as the SI 29-5 connects to the special 15-pin Sub-D connector. The central unit is also fitted with RS 232 interfaces for PC, media and camera control.
