Overview
The infrared conference system has all the advantages of infrared communication
complete with wireless transceiver microphone units. Wireless infrared technology
provides the user with greater flexible whilst configuring the system and freedom of
choice when placing microphones, it guarantees conference privacy and protects the
system from wiretapping and radio interference. It’s the best wireless conference
solutions for small-scale conferences.
