3.2 Radiators
The radiators accept the carrier signals generated by the transmitter and emit infrared
radiation carrying up to 32 audio distribution channels. The radiators are connected to one or
more of the 6 HF BNC outputs of the IR transmitter. Connect a maximum of 30 radiators to
each of these outputs by means of loop-through connections.
The LBB4511/00 has an infrared output of 21Wpp, while the LBB4512/00 has an infrared
output of 42Wpp. Both select automatically the mains power voltage and switch on when the
transmitter is switched on.
The radiator equalizes automatically the attenuation of the signal by the cable. The radiator
initializes the equalization when the radiator is supplied with power and the transmitter is
switched on. The red LED flashes for a brief period of time to indicate that the initialization is
in progress.
When not receiving carrier waves, the radiators switch to standby mode. The temperature
protection mode is also available. It automatically switches the radiators from full to half
power or from half power to standby if the temperature of the IREDs becomes too high.
