These radiators are used to distribute infrared signals throughout the conference venue, enabling delegates to listen to the proceedings by means of personal pocket receivers.


• Universal mains power facility allows use worldwide
• No fan - cooled by convection - resulting in quieter operation and less moving parts to wear out
• LED indicators for radiator status checking
• Communication between radiator and transmitter for easy checking by the operator
• Automatically switches on when transmitter is switched on and vice versa
• Automatic cable equalization ensures maximum transmission efficiency with different quality of cables
• Automatic cable termination simplifies installation
• Temperature protection circuitry automatically switches radiator from full- to half- power if the temperature becomes too high
• Adjustable radiator angle ensures maximum coverage
• IREDs protected by a cover plate, making the units easy to maintain and clean
• Attractive and stylish design

Controls and Indicators

• Two yellow LEDs: one on each radiator panel to indicate that this panel is switched on and is receiving carrier waves from the transmitter
• Two red LEDs: one on each radiator panel to indicate that this panel is in standby mode
• Red and yellow LEDs simultaneously illuminated to indicate the radiator panel is malfunctioning
• Red LED flashing and yellow LEDs to indicate the radiator panel is in temperature protection mode
• Power reduction switch to reduce the output of the radiator to half-power
• Two delay compensation switches to compensate for differences in cable lengths between transmitter and radiators


• Male Euro socket for mains connection
• HF input and output connectors (2 x BNC) for connection to transmitter and loop-through to other radiators
