The transmitter is the central element in the Integrus system. It accepts analog or digital input (from DCN), modulates these signals onto carrier waves and transmits these carrier waves to radiators located in the room. The LBB 4502/04 offers up to a maximum of 4 audio channels. It automatically distributes emergency messages to all channels. An auxiliary mode distributes musical to all channels during a break. Flexible configuration of channels and channel quality modes facilitate efficient distribution. The LBB4511 Integrus Medium Power IR Radiator is used to distribute infrared signals throughout the conference venue, enabling delegates to listen to the proceedings by means of personal receivers. The radiator covers up to 10,750 sq ft (one carrier, 4 standard channels). A power output selection offers efficiency and economy. It is cooled by convection (not a fan) which means it is quiet and has fewer moving parts. The LBB4504/04 4-Channel Digital Infrared Receiver is ergonomically designed and incorporates the latest electronics technology, including a specially designed IC to ensure maximum performance and a long battery life. It can be used for both language and music distribution. The receiver has 2-digit LCD display that also shows battery and reception status. There is no need to scroll through unused channels because the receiver automatically adjusts to list only those in use.
