LBB 3410/05 Infra-red Radiator

Features

X Economic solution for small conference venues

X Covers up to 200 m² (2150 ft²) with one carrier, 4

standard quality channels

X Automatic gain control ensures the IREDs (infra-red

emitting diodes) function with maximum efficiency

X Power output selection for efficiency and economy

Introduction

The LBB 3410/05 low power wide beam radiator is used to

distribute infra-red signals throughout a small conference

venue, enabling delegates to listen to the proceedings by

means of personal receivers.

Functions

• Attractive and stylish design

• Built in power supply

• Automatically switches on when transmitter is switched

on and vice versa

• LED indicators for radiator status checking

• Adjustable radiator angle ensures maximum coverage

• IREDs protected by a front cover, making the units easy

to maintain and clean

Limitations

• Only the first 4 carriers can be transmitted

• Not more than 100 m (328 ft) cable length from

transmitter to last radiator

• Direct connection of the radiators to the transmitter with

equal cable length. In loop-through connection, the total

cable length from the first to the last radiator may not

exceed 5 meters.

Reason: there are no facilities on this radiator for

compensating the cable signal delay

• Don’t use this radiator in combination with LBB 4511/00

and LBB 4512/00 radiators in one system, as the internal

signal delay of these radiators is different

• No automatic cable termination: the termination plug has

to be connected to the last radiator in a trunk

• No communication of the radiator status to the

transmitter

• Using this radiator at 105 to 125 V requires internal

adjustments

Controls and Indicators

• Green LED to indicate the radiator is switched on and is

receiving carrier waves from the transmitter

• Red LED, which illuminates when the infra-red output

power of the radiator is reduced to 70% or less of normal

output level

• Power reduction switch to reduce the output of the

radiator to half-power

Interconnections

• Male mains socket for mains connection

• HF input and output connectors (2 x BNC) for connection

to transmitter and loop-through to other radiators
