The central unit allows to digitally connect and manage up to 120 consoles on four lines (30 each line) by means of cable CAT5 UTP. An audio reinforcement system can be connected through 4 LINE level outputs and turned off or attenuated with the insertion of groups of microphones; a recorder and a remote conference audio system can also be connected as well as a personal computer through USB or RS232.
Moreover, it has two inputs MIC/LINE that can be set by PC with priority or in mixing mode over the other consoles. It includes a Smartcard reader/writer in order to set up the features of every microphone set and to activate the available options. The main unit, operating in stand-alone mode, allows to use the system for a basic conference and voting thanks to its graphical backlit display and the interactive push-buttons.
It allows to simply recall recorded presets corresponding to several configurations of different conference halls or to various uses of the same one, activating different numbers of microphone units, eventually assigning various features to the same one (Secretary, Chairman, Delegate), or again various operation modalities (e.g. free or timed conference, with or without Smartcard, with right or not of voting, a various number microphone units that can be turned on at the same time etc.). It allows the monitoring of the conference by means of a loudspeaker monitor or from the 6,3 mm jack headphone output, available on the frontal panel.
If used independently, the main unit allows to adjust the volume of the LINE outputs (all together or one only at a time), the loudspeaker frontal monitor volume and some basic features as the calendar-clock.
