Integrus Radiators

3.4.1

Medium and High Power Radiators

These units accept the carrier signals generated by the transmitter and emit infra-red
radiation carrying up to 32 audio distribution channels. They are connected to one or more of
the four HF BNC outputs of the IR transmitter. A maximum of 30 radiators can be connected
to each of these outputs by means of loop-through connections.
The LBB 4511/00 has an infra-red output of 16 Wpp, while the LBB 4512/00 has an infra-red
output of 32 Wpp. Both have an automatic mains power voltage selection and are switched on
automatically when the transmitter is switched on.
The attenuation of the signal by the cable is equalized automatically by the radiator. When the
radiator is supplied with power and the transmitter is switched on, the radiator initializes the
equalisation. The red LEDs flash 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. There is also a
temperature protection mode which automatically switches the radiators from full to half
power or from half power to stand-by if the temperature of the IREDs becomes too high.

Mains input - Male Euro mains connector. The radiators have automatic mains voltage
selection.
IR signal input/loop-through - Two HF BNC connectors for connecting the radiator to
the transmitter and for loop-through connection to other radiators. Automatic cable
termination is achieved by a built-in switch in the BNC connectors.
