Description
Bosch Integrus · Reference LBB4511/00
Interpretation,
distributed by light.
The LBB4511/00 is the medium-power radiator of the Integrus system. It receives the language channels from the transmitter and distributes them in the room as infrared radiation, picked up by the participants' pocket receivers. It covers up to 1,300 m² with one carrier of four channels.
- 1,300 m²1 carrier, 4 channels
- 260infrared diodes
- 100 Win operation
- 6.8 kgwithout bracket
Silent above the delegates
The radiator has no fan: its fins cool it by simple convection, with no noise and no moving part to wear out. If its diodes get too hot, a protection circuit switches it to half power by itself. On the ceiling, Bosch asks for at least one cubic metre of free space behind it so that air can circulate.
Looped through on a single cable
At the rear, two BNC sockets receive the high-frequency signal from the transmitter and pass it on to the next radiator: up to thirty radiators can follow one another on one transmitter output. Cable termination and line-loss equalisation are automatic. Two ten-position switches compensate for cable length differences between radiators, and a third halves the emission when the room is small. The radiator switches on and goes to standby together with the transmitter.
Rear of an Integrus radiator: safety eye (1), mains socket (4), BNC input and output (5), half power (6), delay compensation (7).On the ceiling, on a stand or on the wall
The supplied suspension bracket fixes the radiator directly to the ceiling; its angle adjusts from 0 to 90° in 15° steps to aim at the listening area. Plates with M10 and 1/2 inch Whitworth threads, also supplied, fit it to most floor stands, at 0, 15 or 30°, with a mounting height of at least 1.80 m. For the wall, the LBB3414/00 wall bracket is needed. A safety eye takes a safety sling.

The radiator only works with an Integrus transmitter, connected by coaxial cable to its BNC sockets. For a larger room, the LBB4512/00 doubles the covered area.
The Integrus INT-TXO transmitter drives the radiator, and the LBB4550/10 battery equips the receivers. The rest of the system is in the video conferencing section and on the Bosch page.

Frequently asked questions about this product
What area does the LBB4511/00 radiator cover?
Up to 1,300 m² with one carrier carrying 4 standard-quality channels. Coverage decreases when the transmitter spreads its channels over several carriers, and it also depends on the mounting height and angle. For a larger room, several radiators are looped through on the same transmitter output, or the high-power LBB4512/00 model is chosen.
What is the difference between the LBB4511/00 and the LBB4512/00?
Power. The LBB4511/00 carries 260 diodes for 12 W/sr of peak intensity and covers up to 1,300 m²; the LBB4512/00 carries 480, covers twice the area and draws 180 W instead of 100 W. The LBB4511/00 is also lower (200 mm instead of 300) and lighter. It targets small and medium rooms.
How does the radiator connect to the transmitter?
By coaxial cable on its BNC sockets: one input coming from the Integrus transmitter, one output to loop through to the next radiator, up to 30 radiators per HF output. Cable termination is automatic, as is the equalisation of line losses. Two switches compensate for differences in cable length between the radiators of the same room.
How is it mounted on the ceiling, on a wall or on a floor stand?
The supplied suspension bracket allows direct ceiling mounting, with an angle adjustable from 0 to 90° in 15° steps. The supplied plates, threaded M10 and 1/2 inch Whitworth, fit most floor stands (0, 15 or 30°). Wall mounting requires the LBB3414/00 bracket, sold separately. A safety eye takes a safety sling.
Does the radiator make noise when operating?
No, it has no fan: it is cooled by convection. If its diodes get too hot, it switches to half power by itself. Air must therefore circulate around it, with at least 1 m³ of free space behind it when ceiling-mounted. It switches on and goes to standby automatically with the transmitter.
