DIGITAL CONFERENCE MAIN UNIT

This conference system uses digital technologies according to the European Community’s IEC914 and ISO standards. It is composed of a main unit – CONFD – and two microphone units – Delegate (BMDD) and President (BMCD) – that feature high sensitivity, a wide frequency response, an internal loudspeaker and a cardioid electret microphone with a lighted ring for the visual identification of the microphone in use. The system is precabled to ensure fast and easy installation. The device may include up to 64 microphone stations, daisy-chained on four independent lines (or a maximum of 30 stations on each line). The system involves the use of several expansion units – EXCONFD. Every expansion unit can support up to 60 stations divided on six lines (never use more than 30 stations on each line).Adding four expansion units, the system can control up to 254 stations. The serial connection of each station is achieved through single multicore, prerouted cables that may be used either for fixed or mobile systems.
