System Overview
System Overview
Integrus is a system for wireless distribution of audio signals via infrared radiation. It can be used in a simultaneous interpretation system for international conferences where multiple languages are used. To enable all participants to understand the discussion, interpreters simultaneously translate the speaker's language as required. These interpretations are distributed throughout the conference venue, and delegates select the language of their choice and listen to it through headphones. The Integrus system can also be used for music distribution (mono as well as stereo).
Figure 3.1: Integrus system overview (with DCN-system as input)
The Integrus Language Distribution System comprises one or more of the following:
Infrared transmitter
The transmitter is the core of the Integrus system. Four types are available:
– INT‑TX04 with inputs for 4 audio channels
– INT‑TX08 with inputs for 8 audio channels
– INT‑TX16 with inputs for 16 audio channels
– INT‑TX32 with inputs for 32 audio channels
The transmitter can be directly connected to the DCN Next Generation conference system
(see section Connection, page 42).

Integrus Radiators
The radiators accept the carrier signals generated by the transmitter and emit infrared radiation carrying up to 32 audio distribution channels. They are connected to one or more of the six 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 infrared output of 21 Wpp, while the LBB 4512/00 has an infrared output of 42 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 equalization. The red LED 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 standby if the temperature of the IREDs becomes too high.

IR radiation
The Integrus system is based on transmission by modulated infrared radiation. Infrared radiation forms part of the electromagnetic spectrum, which is composed of visible light, radio waves and other types of radiation. It has a wavelength just above that of visible light. Like visible light, it is reflected from hard surfaces, yet passes through translucent materials such as glass. The infrared radiation spectrum in relation to other relevant spectra is shown in the next figure.

Signal Processing
The Integrus system uses high frequency carrier signals (typically 2-8 MHz) to prevent
interference problems with modern light sources (see section The footprint of the radiator,
page 23). The digital audio processing guarantees a constant high audio quality.
The signal processing in the transmitter consists of the following main steps (see the next figure):
1.
A/D conversion - Each analogue audio channel is converted to a digital signal.
2.
Compression - The digital signals are compressed to increase the amount of information that can be distributed on each carrier. The compression factor is also related to the required audio quality.
3.
Protocol Creation - Groups of up to four digital signals are combined into a digital information stream. Extra fault algorithm information is added. This information is used by the receivers for fault detection and correction.
4.
Modulation - A high frequency carrier signal is phase-modulated with the digital information stream.
5.
Radiation - Up to 8 modulated carrier signals are combined and sent to the IR radiators, which convert the carrier signals to modulated infrared light.
In the IR receivers a reverse processing is used to convert the modulated infrared light to separate analogue audio channels.

Quality modes
The Integrus system can transmit audio in four different quality modes:
– Mono, standard quality, maximum 32 channels
– Mono, premium quality, maximum 16 channels
– Stereo, standard quality, maximum 16 channels
– Stereo, premium quality, maximum 8 channels
The standard quality mode uses less bandwidth and can be used for transmitting speech. For music the premium quality mode gives near CD quality.

Carriers and channels
The Integrus system can transmit up to 8 different carrier signals (depending on the transmitter type). Each carrier can contain up to 4 different audio channels. The maximum number of channels per carrier is dependent on the selected quality modes. Stereo signals use twice as much bandwidth as a mono signals; premium quality uses twice as much bandwidth as standard quality.
Per carrier a mix of channels with different quality modes is possible, as long as the total available bandwidth is not exceeded. The table below lists all possible channel combinations per carrier:

Aspects of Infrared distribution systems
Planning | en
23
A good infrared distribution system ensures that all delegates in a conference venue receive the distributed signals without disturbance. This is achieved by using enough radiators, placed at well planned positions, so that the conference venue is covered with uniform IR-radiation of adequate strength. There are several aspects that influence the uniformity and quality of the infrared signal, which must be considered when planning an infrared radiation distribution system. These are discussed in the next sections.
Directional sensitivity of the receiver
The sensitivity of a receiver is at its best when it is aimed directly towards a radiator. The axis of maximum sensitivity is tilted upwards at an angle of 45 degrees (see the next figure).
Rotating the receiver will decrease the sensitivity. For rotations of less than +/- 45 degrees this effect is not large, but for larger rotations the sensitivity will decrease rapidly.

Figure 4.3: Directional characteristics of the receivers
The footprint of the radiator
The coverage area of a radiator depends on the number of transmitted carriers and the output power of the radiator. The coverage area of the LBB 4512/00 radiator is twice as large as the coverage area of the LBB 4511/00. The coverage area can also be doubled by mounting two radiators side by side. The total radiation energy of a radiator is distributed over the transmitted carriers. When more carriers are used, the coverage area gets proportionally smaller. The receiver requires a strength of the IR signal of 4 mW/m

Footprint
The cross section of the 3-dimensional radiation pattern with the floor of the conference venue is known as the footprint (the white area in the following three figures). This is the floor area in which the direct signal is strong enough to ensure proper reception, when the receiver is directed towards the radiator. As shown, the size and position of the footprint depends on the mounting height and angle of the radiator.

Ambient lighting
The Integrus system is practically immune for the effect of ambient lighting. Fluorescent lamps
(with or without electronic ballast or dimming facility), such as TL lamps or energy saving lamps give no problems with the Integrus system. Also sunlight and artificial lighting with

4.2.4
Language Distribution System incandescent or halogen lamps up to 1000 lux give no problems with the Integrus system.
When high levels of artificial lighting with incandescent or halogen lamps, such as spotlights or stage lighting are applied, you should directly point a radiator at the receivers in order to ensure reliable transmission. For venues containing large, unscreened windows, you must plan on using additional radiators. For events taking place in the open air a site test will be required in order to determine the required amount of radiators. With sufficient radiators installed, the receivers will work without errors, even in bright sunlight.
Objects, surfaces and reflections
The presence of objects in a conference venue can influence the distribution of infrared light.
The texture and color of the objects, walls and ceilings also plays an important role. Infrared radiation is reflected from almost all surfaces. As is the case with visible light, smooth, bright or shiny surfaces reflect well. Dark or rough surfaces absorb large proportions of the infrared signal (see the next figure). With few exceptions it cannot pass through materials that are opaque to visible light.
100% 40% 100% 80%
4.2.5
Figure 4.9: The texture of the material determines how much light is reflected and how much is absorbed
Problems caused by shadows from walls or furniture can be solved by ensuring that there are sufficient radiators and that they are well positioned, so that a strong enough infrared field is produced over the whole conference area. Care should be taken not to direct radiators towards uncovered windows, as most of this radiation will subsequently be lost.
Position the radiators
Since infrared radiation can reach a receiver directly and/or via diffused reflections, it is important to take this into account when considering the positioning of the radiators. Though it is best if receivers pick up direct path infrared radiation, reflections improve the signal reception and should therefore not be minimized. Radiators should be positioned high enough not to be blocked by people in the hall (see the next two figures).

The figures below illustrate how infrared radiation can be directed to conference participants.
In figure 4.12, the participant is situated clear from obstacles and walls, so a combination of direct and diffused radiation can be received. Figure 4.13 shows the signal being reflected from a number of surfaces to the participant.

For concentrically arranged conference rooms, centrally placed, angled radiators located high up can cover the area very efficiently. In rooms with few or no reflecting surfaces, such as a darkened film-projection room, the audience should be covered by direct path infrared

Overlapping footprints and black spots
When the footprints of two radiators partly overlap, the total coverage area can be larger than the sum of the two separate footprints. In the overlap area the signal radiation power of two radiators are added, which increases the area where the radiation intensity is larger than the required intensity. However, differences in the delays of the signals picked up by the receiver from two or more radiators can result in that the signals cancel each other out (multi path effect). In worst-case situations this can lead to a loss of reception at such positions (black spots).
The next two figures illustrate the effect of overlapping footprints and differences in signal delays.
Figure 4.17: Increased coverage area caused by added radiation power
Figure 4.18: Reduced coverage area caused by differences in cable signal delay
The lower the carrier frequency, the less susceptible the receiver is for differences in signal delays. The signal delays can be compensated by using the delay compensation switches on
the radiators (see section Determine the radiator delay switch positions, page 60).

Rectangular footprints
Determining the optimal number of infrared radiators required to give 100% coverage of a hall can normally only be done by performing a site test. However, a good estimation can be made by using 'guaranteed rectangular footprints'. Figure 4.19 and 4.20 show what is meant by a rectangular footprint. As can be seen, the rectangular footprint is smaller than the total footprint. Note that in figure 4.20 the 'offset' X is negative because the radiator is actually mounted beyond the horizontal point at which the rectangular footprint starts.

height is the distance from the reception plane and not from the floor.

Guaranteed rectangular footprints can also be calculated with the footprint calculation tool
(available on the documentation DVD). The given values are for one radiator only, and therefore do not take into consideration the beneficial effects of overlapping footprints. The beneficial effects of reflections are also not included. As rule of thumb can be given for systems with up to 4 carriers that if the receiver can pick up the signal of two adjacent radiators, the distance between these radiators can be increased by a factor 1.4
approximately (see the next figure).

Plan radiators
Use the following procedure to plan the radiators:
1.
Follow the recommendations in section Aspects of Infrared distribution systems, page 23 in
order to determine the positioning of the radiators.
2.
Look up (in the table) or calculate (with the footprint calculation tool) the applicable rectangular footprints.
3.
Draw the rectangular footprints in the lay-out of the room.
4.
If the receiver can pick up the signal of two adjacent radiators in some areas, determine the overlap effect and draw the footprint enlargement(s) in the lay-out of the room.
5.
Check whether you have sufficient coverage with the radiators at the intended positions.
6.
If not so, add additional radiators to the room.
See the figures 4.14, 4.15 and 4.16 for examples of a radiator lay out.

Radiators in permanent installations can be either fixed to a wall, hung under a ceiling or balcony or secured to any sturdy material, using the suspension bracket supplied with the radiator. The mounting angle can be adjusted for optimal coverage. For wall mounting a separate bracket (LBB 3414/00) is also required. In non-permanent installations, a floor stand can be used.
Warning!
When you install the radiator in a ceiling, you must leave at least 1 m

Mount radiator on a ceiling
The radiators can be attached to the ceiling using the supplied suspension bracket. This ensures enough space for a proper air flow around the radiator. Mounting a radiator in the ceiling will in most cases require a forced air flow by means of a ventilator to prevent overheating. If this is not possible, switch the radiator to half power.
Mount radiator on horizontal surfaces
When the radiator has to be positioned a horizontal surface (e.g. on top of an interpreter booth), the distance between the radiator and the surface must be at least 4 cm (1.5 inch) to enable enough air flow around the radiator. This can be achieved by using the suspension bracket as a support. If this is not possible, switch the radiator to half power. If the radiator is used at full power on top of an interpreter booth, the ambient temperature must not exceed
35° C.
Secure the radiator with safety cord.
The radiator is supplied with a safety eye to secure the radiator with a safety cord (not supplied).
1.
Mount the safety eye properly in the hole of the radiator.
2.
Make sure that: The minimum strength of the safety cord, mounting material, shackle and supporting building structure should withstand 1,500 N. The length of the safety cord is not more than 20 cm longer than needed.
3.
Mount the safety cord to the safety eye.
4.
Mount the safety cord to the supporting building structure.
Warning!
Suspending any object is potentially dangerous and should only be attempted by individuals who have a thorough knowledge of the techniques and regulations of rigging objects overhead. Bosch strongly recommends that radiators be suspended taking into account all current national, federal, state and local regulations.
It is the responsibility of the installer to ensure that radiators are safely installed in accordance with all such regulations. If radiators are suspended, Bosch strongly recommends that the installation is inspected at least once a year. If any sign of weakness or damage is detected, remedial action should be taken immediately.
Integrus receivers
The infrared receivers can operate with disposable batteries (2x AA-size alkaline cells) or with a rechargeable battery pack (LBB 4550/10).
Insert the batteries or the battery pack in the receiver with the correct polarity as indicated in the battery compartment. The battery pack has a separate connection cable which must be connected to the receiver. When this connection is not present, the charging circuitry in the receiver will not work. This also prevents the unwanted charging of disposable batteries. The battery pack has a temperature sensor which prevents overheating during charging.
For more information about charging the battery pack see section Integrus Charging Units,
Notice!
Disposable batteries and battery packs at the end of their technical lives should be discarded with due care for the environment. When possible, take batteries to a local recycling station.

Set channel quality and assign inputs to channels (4D)
The audio quality of the channels (mono/stereo, standard/premium) can be set in sub-menu
4D. The quality can be set the same for all channels or for each channel separately. Note that choosing stereo and/or premium quality uses more bandwidth and decreases the number of
available channels (see section Carriers and channels, page 22). In stereo mode, the left signal
is always an even numbered input. The next higher input number is used for the right signal.

Set the output power selection switch
The radiators can be switched to half power. This can be used when full power is not required, e.g. when a mobile system is used in a small conference venue.
Also switch a radiator to half power when an adequate air flow can not be guaranteed, e.g.
when the radiator is mounted on top of an interpreters booth.
Reducing the power when possible saves energy and increases the lifetime.
When a radiator is in half power mode, half the number of IREDs are switched off, which results in a visible pattern as shown in the next figure.

Set the delay switches
Refer to Determine the radiator delay switch positions, page 60 how to determine the radiator
delay switch positions.
Caution!
Turn the delay switches carefully to a new position until you feel that it clicks into position, to prevent that a switch is positioned between two numbers, which would result in a wrong delay setting.
Determine the radiator delay switch positions
As described in section Overlapping footprints and black spots, page 29, differences in the
delays of the signals picked up by the receiver from two or more radiators can cause black spots as a result of the multi path effect.
The signals picked up by the receiver are delayed by:
– the transmission from transmitter to radiator through the cable (cable signal delay)
– the transmission from radiator to receiver through the air (radiation signal delay)
– for systems with two or more transmitters: the transmission through the slave transmitter(s)
To compensate the signal delay differences, the delay of each radiator can be increased.
These signal delays can be set with the delay switches at the back of the radiator.
The cable signal delays can be determined in the following two ways:
– by measuring the cable lengths
– by measuring the impulse response time with a delay measurement tool
In both cases the cable signal delays can be calculated manually and with the delay switch calculation tool (available on the documentation DVD).
It is not necessary to calculate the cable signal delay in case:
– the radiators are directly connected to the transmitter with equal cable length;
– radiators are loop-through connected, but with less than 5 m distance between the first and last radiator in a trunk, and with equal cable length between the first radiator in each trunk and the transmitter.
In these cases set the delay switches on all radiators to zero and determine whether to
compensate for radiation signal delay (see section Systems with more than 4 carriers and a
radiator under a balcony, page 65).
The next sections describe how to calculate the delay switch positions manually for systems with one transmitter, or two or more transmitters. See the delay switch calculation tool for the procedures how to calculate the delay switch positions automatically.
Notice!
The delay switch calculation tool eases the calculation of the delay switch positions.
System with one transmitter
There are two ways to determine the delay switch positions:
– Measuring the cable lengths
– Using a delay measuring tool
Both methods are described in the next sections.
2013.11 | V1.4 | Operation manual Bosch Security Systems B.V.
Language Distribution System Configuration | en
61
Notice!
For systems with a cable length difference of more than 50 meters, it is recommended to use a measurement tool to determine the delay differences in order to calculate the delay switch positions.
Determining delay switch positions by measuring the cable lengths
Use the following procedure to determine the delay switch position based on cable lengths:
1.
Look up the cable signal delay per meter of the used cable. The manufacturer specifies this factor.
2.
Measure the lengths of the cables between the transmitter and each radiator.
3.
Multiply the lengths of the cables between the transmitter and each radiator with the cable signal delay per meter. These are the cable signal delays for each radiator.
4.
Determine the maximum signal delay.
5.
Calculate for each radiator the signal delay difference with the maximum signal delay.
6.
Divide the signal delay difference by 33. The rounded off figure is the signal delay switch position for that radiator.
7.
Add delay switch positions for radiators under a balcony, if applicable (see section
Systems with more than 4 carriers and a radiator under a balcony, page 65).
8.
Set the delay switches to the calculated switch positions.

Notice!
The used cable signal delay per meter is an example. Use the actual signal delay per meter in this calculation as specified by the manufacturer.
Determining delay switch positions by using a delay measuring tool
The most accurate way to determine the cable signal delays is to measure the actual signal delay for each radiator as described in the following procedure:
1.
Disconnect the cable from a radiator output of the transmitter and connect this to a delay measurement tool.
2.
Disconnect a radiator from this cable.
3.
Measure the impulse response time (in ns) of the cable(s) between the transmitter and the radiator.
4.
Reconnect the cable to the radiator and repeat steps 2 to 4 for the other radiators that are connected to the same transmitter output.
5.
Reconnect the cable t the transmitter and repeat step 1 to 5 for the other radiator outputs of the transmitter.
6.
Divide the impulse response times for each radiator by two. These are the cable signal delays for each radiator.
7.
Determine the maximum signal delay.
8.
Calculate for each radiator the signal delay difference with the maximum signal delay.
9.
Divide the signal delay difference by 33. The rounded off figure is the delay switch position for that radiator.
10. Add delay switch positions to radiators under a balcony, if applicable (see section
Systems with more than 4 carriers and a radiator under a balcony, page 65)
11. Set the delay switches to the calculated delay switch positions.
Caution!
Turn the delay switches carefully to a new position until you feel that it clicks into position, to prevent that a switch is positioned between two numbers, which would result in a wrong delay setting.

Notice!
The calculated delay switch positions based on impulse response time can differ from the calculated delay switch positions based on cable lengths. This is caused by the accuracy of the measurements and the accuracy of the cable signal delay factor per meter as specified by the manufacturer of the cable. If the impulse response time is measured correctly, the calculated delay switch positions will be the most accurate.
System with two or more transmitters in one room
When radiators in one multi purpose room are connected to two transmitters, an extra signal delay is added by:
– Transmission from master transmitter to slave transmitter (cable signal delay).
– Transmission through the slave transmitter.
Use the following procedure to determine the delay switch positions in a master-slave configuration:
1.
Calculate the cable signal delay for each radiator, using the procedures for a system with one transmitter.
2.
Calculate the signal delay of the cable between the master and the slave transmitter in the same way as for cables between a transmitter and a radiator.
3.
Add to the cable signal delay of the cable between the master and the slave, the delay of the slave transmitter itself: 33 ns. This gives the master-to-slave signal delay.
4.
Add the master-to-slave signal delay to each radiator connected to the slave transmitter.
5.
Determine the maximum signal delay.
6.
Calculate for each radiator the signal delay difference with the maximum signal delay.
7.
Divide the signal delay difference by 33. The rounded off figure is the signal delay switch position for that radiator.
8.
Add delay switch positions to radiators under a balcony, if applicable (see section
Systems with more than 4 carriers and a radiator under a balcony, page 65)
9.
Set the delay switches to the calculated delay switch positions.
Caution!
Turn the delay switches carefully to a new position until you feel that it clicks into position, to prevent that a switch is positioned between two numbers, which would result in a wrong delay setting.

The receivers can be switched to a test‑mode to get an indication of the reception quality for each carrier separately. To activate the test-mode:
1.
Push the channel selector to the Up‑position
2.
Press the on/off button and hold both for ca. 2 seconds
3.
When in test-mode, switch between carriers by using the channel selector
For each carrier the display shows a relative value of the signal strength, Figure of
Merit(FOM), and a graphical quality indication symbol.
The reception quality can be assessed as follows:
Indication
00-39
40-49
Quality
Good reception. Very good audio quality.
Weak reception. Ticks in the audio.
50-90 No or bad reception. Poor audio quality.
The test mode is deactivated when the receiver is switched off.
Test the coverage area
An extensive reception quality test must be done to make sure that the whole area is covered with IR radiation of adequate strength and that there are no black spots. Such a test can be done in two ways:
Testing during installation
1.
Check that all radiators are connected and powered up and that no loose cables are connected to a radiator. Switch the transmitter off and on to re-initialise the auto equalisation of the radiators.
2.
Set the transmitter in the Test-mode (see section Set transmission (4A), page 52). For
each channel, a different test tone frequency will be transmitted.
3.
Set a receiver on the highest available channel and listen via the headphones to the transmitted test tone.
4.
Test all positions and directions (see next paragraph).
Testing during a meeting
1.
Set a receiver in the Test-mode and select the highest available carrier. The quality of the
received carrier signal is indicated on the display of the receiver (see section Integrus
2.
Test all positions and directions (see next paragraph). The quality indication should be between 00 and 39 (good reception).
Testing all positions and directions
With the transmitter and receiver in one of the two test modes, go around the conference hall and test the reception quality at every position where the infrared signals must be received.
When an area is detected where there is bad reception or even no reception at all, three main causes must be considered:
Bad coverage
The receiver can not pick-up infrared radiation of adequate strength. This can be because the tested position is outside the footprint of the installed radiators or the radiation is blocked by obstacles such as a column, an overhanging balcony or other large objects.
Bosch Security Systems B.V.
Operation manual 2013.11 | V1.4 |
68
en | Testing Language Distribution System
Check that you used the correct footprints for the system design, that radiators with enough output power are installed and that a radiator is not accidentally switched to half power operation. When the bad reception is caused by a blocked radiation path, try to remove the blocking obstacle or add an extra radiator to cover the shaded area.
Black spots
The receiver picks-up IR signals from two radiators which cancel out each other.
The black spot can be identified by the observation that the bad reception only occurs along a specific line and/or when good reception returns when the receiver is rotated to another direction. This can be confirmed by keeping the receiver in the position and direction with the bad reception and then either shading-off the radiation from one radiator with your hand or switching off one radiator. If this improves the reception quality, then the black spot is causing the problem. Note that IR radiation that is reflected from a surface with a high reflectively can also cause black spots.
Black spots can occur in case a transmitter is located in the same room as the radiators.
– In that case, disable the mini IR radiator of the transmitter with the configuration menu
(see section Enable / disable IR-monitoring (4M), page 58).
– Check that the signal delay compensation switches on the radiators are set to the correct value and that a switch is not accidentally positioned between two numbers.
– Re-check your system design. When necessary, reduce the distance between the two radiators that cause the problem and/or add an extra radiator.
Note that due to the physical characteristics of the signal distribution, it is not always possible to completely avoid black spots.
Interference from IR systems
IR assisted hearing systems and IR microphones operating at frequencies above 2 MHz, can disturb the reception at the lowest carriers. If such is the case, disable the lowest two carriers
(see section Disable or enable carriers (4G), page 56) and re-check the reception.

The display of the receiver can show the following information:
– The channel number.
– A battery symbol when the batteries or the battery pack is almost empty.
– Antenna symbol when the signal reception is okay. No antenna symbol when no signal reception.
During short interruptions in the reception, the receiver mutes the headphones output.
In case standby mode is enabled, the receiver automatically switches to standby mode when no adequate IR signal is detected for more than 1 minute (e.g. when a delegate leaves the conference room). When the receiver is in standby mode, press the on button to return to normal operation.
Notice!
When the receiver is not used, disconnect the headphones. This ensures that the receiver is totally switched off and no energy is consumed from the batteries or the battery pack.

Notice!
These charging units are only intended to charge LBB 4540 receivers with a LBB 4550/10 battery pack. You cannot charge other receiver types with the LBB 4560 charging units, nor can you use other charging units to charge LBB 4540 receivers.
It is preferred to switch on the charging unit before inserting the receivers. Receivers can be inserted or removed without damage while the charging unit is switched on.
Charge the battery pack to full capacity before using them for the first time.
The charger always applies fast charge during the first 10 minutes after inserting a receiver.
Inserting the receiver multiple times with a fully charged battery pack should therefore be avoided, as this will damage the battery pack.
Continuously charging the receiver will not damage the receiver or battery pack. Receivers can therefore safely be left in their charging positions when they are not used.
