The SDC 8200 CU 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 powers up to 120 conference terminals in six cable lines.
SDC 8200 CU can handle up to 28 languages. Licenses for the floor language and four translations are included in the delivery, further licenses for an expansion to 8 or 28 languages are available separately.
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.
Up to 12 central units can be daisy-chained to create systems with up to 1,024 conference terminals.
