  The infrared conference system has all the advantages of infrared communication complete with wireless transceiver microphones units. Wireless infrared technology provides the user with greater flexible whilst configuring the system and freedom of choice when playing 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.
   
• Main Features
  
  ◆ Infrared transmission technology guarantees privacy
  ◆ Perfect sound quality as CD from the microphone
  ◆ IR communication system eliminates the need of connection the conference units. Installation can be done quick and smart without cumbersome arrangements
  ◆ Fullyfunctions (Discuss & Video tracking), support FIFO (1/2/3), Limit (1/2/3) and chairman only mode, microphones in one system up to 127 units
  ◆ Microphones can be operated on either their build-in rechargeable LI-Polymer batteries or AC power supply, battery lie approx. 6 hours during speech and approx. 30 hours when standby
  ◆ Microphone OLED can display system and conference information
  ◆ Excellent immunity to RF interference from mobile phones and RF devices
