The Educorps Conference System brings a multiplemode remote conferencing to the meeting room, via a standard telephone line, a mobile phone, or PC-based IP telephony. It provides a full range of features for ensuring clear sound for efficient and effective conferences, and at a remarkably high cost/performance ratio. The system does away with the need for a conference hall with professionally and permanently installed equipment for small-to-medium-sized meetings. Setting up the Chairman Unit and Delegate Unit is quick and easy. The basic requirements are simply to attach the Chairman and Delegate Units to the systems Central Unit, and connect each Delegate Unit, accordingly. Depending on an application, a unit may be farther apart from each other so an optional Extension Cord (2m/10m) can be attached. Up to 70 units, including multiple Chairman Units, may be attached to a single Central Unit (35 per line), and system expansion to 140 or 210 units is possible by adding a 2nd or 3rd extension Central Unit. Operating the conference unit goes smoothly and efficiently. An optimized unidirectional gooseneck microphone and wide frequency response speaker ensure optimally clear voice transmission, with everyone clearly heard. Simply pushing the Talk button activates the microphone, while also deactivating the speaker in the unit, to prevent howling. The Chairman Unit can selectone, three or six Delegate Units for simultaneous operation, and if several Chairman Units are included, they may speak simultaneously. Smooth operation of the conference is assured by a Chairman Unit’s priority function.Long-term archival recording is made possible by connecting an optional alternating recording device to the center amplifier, and each unit also has its own recording output jack.
