General Description
The SDC 8000 CU central unit is the heart of Sennheiser‘s SDC 8000 digital con-
ference and interpretation system. All settings for the system are made via the
central unit‘s local configuration menu. Accommodated in a 19“ full-metal hous-
ing, the SDC 8000 CU powers up to 90 conference terminals in six cable lines.
SDC 8000 CU can handle up to 28 languages. Licenses for the floor language and two
translations are included in the delivery, further licenses for an expansion to 4, 8 or
28 languages are available separately. The central unit features two analogue audio
inputs, e.g. for wireless microphones, and an analogue 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 9-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.
