Integrus

System Overview

System Overview

Integrus is a system for wireless distribution of audio signals via infra-red 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 proceedings, 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).

IOM-INT | V1.1 | 2010.12

Figure 3.1

Integrus system overview (with DCN-system as input)

The Integrus Language Distribution System comprises one or more of the following:

Infra-red transmitter

The transmitter is the core of the Integrus system. Four types are available:

– INT-TX04 with inputs for 4 audio channels




The transmitter can be directly connected to the DCN Next Generation conference system

(see section 6 ).

Interface modules

One of two different interface modules can be mounted in the transmitter housing to connect the transmitter to a wide range of conference systems:

– LBB 3423/20 Integrus DCN interface module to connect to the Digital Congress Network

(DCN).

– LBB 3222/04 Integrus audio input and interpreters module to connect to analogue discussion and conference systems (such as CCS 800) or to LBB 3422/20 6-channel interpreters desks.

Infra-red radiators

Three types of radiators are available:

– LBB 3410/05 low power wide beam radiator for small conference venues

– LBB 4511/00 medium-power radiator for small/ medium conference venues

– LBB 4512/00 high-power radiator for medium/large conference venues

All three types can be switched between full and half power use. They can be mounted on walls, ceilings or floor stands.

Infra-red receivers

Three multi-channel infra-red receivers are available:

Integrus Radiators

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.

Low Power Wide Beam Radiator

This radiator is designed for small or medium-sized conference venues. The radiator has an infra-red output of 3 Wpp and they have a built-in power supply and are switched on automatically when the transmitter is switched on. A mains cable is provided. When not receiving carrier waves, the radiators switch to standby mode. They can be mounted on walls

and ceilings or on a floor stand. Figure 3.7 and Figure 3.8 show front and rear views of the

radiators.

6 Red LED - indicates that the radiator output is 70% or less of the normal output level.

Radiator status indication

When the radiator is transmitting, the green LED mounted internally on a printed circuit board illuminates. If there is a failure in the radiator, a red LED illuminates on the printed circuit board.

Mains voltage selection

Mains voltage selection of 115 V or 230 V is internally selectable. On delivery the radiator is set for 230 Va.c. operation. To alter the mains voltage selection for the LBB 3410/05 radiators, it is necessary to solder two leads to contacts on the printed circuit board (PCB) inside the radiator. To locate the PCB, remove the four securing screws at the rear of the radiator and remove the unit from its housing. Remove the PCB from its mounting by

removing the PCB's six securing screws and the small connector X1 (Figure 3.9). To select 115

V operation, solder two small leads, one connecting X4 to X6 and one connecting X5 to X7.

Then remove the small SMD resistor R3. When this is completed replace fuse F1 (160 mA) with a fuse rated at 350 mA.

Limitations

– Not more than the first 4 carriers can be transmitted.

– Not more than 100 m cable length from transmitter to last radiator.

– Directly connection of the radiators to the transmitter with equal cable length. In loopthrough 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.




3.5

Integrus

– 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 are 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.

Integrus Receivers

LBB 4540 receivers are available for 4, 8 or 32 channels. They can operate with a rechargeable

NiMH battery pack or with disposable batteries and have controls for channel selection, volume adjustment and an on/off push button. All receivers have a 3.5 mm (0.14 inch) stereo jack output socket for mono or stereo headphones.

An LCD display shows the channel number and indicators for signal reception and low battery power.

Charging circuitry is included in the receiver.

System technology

IR radiation

The Integrus system is based on transmission by modulated infra-red radiation. Infra-red 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 infra-red radiation spectrum in relation to other relevant spectra is shown

in Figure 4.1.

Signal Processing

The Integrus system uses high frequency carrier signals (typically 2-8 MHz) to prevent

interference problems with modern light sources (see section 4.2.2 ). The digital audio

processing guarantees a constant high audio quality.

The signal processing in the transmitter consists of the following main steps (see Figure 4.2):

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.

Planning | en 17

5.

Radiation - Up to 8 modulated carrier signals are combined and sent to the IR radiators, which convert the carrier signals to modulated infra-red light.

In the IR receivers a reverse processing is used to convert the modulated infra-red light to separate analogue audio channels.

Overview of the signal processing (for one carrier)

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 Infra-red distribution systems

A good infra-red 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 IRradiation of adequate strength. There are several aspects that influence the uniformity and quality of the infra-red signal, which must be considered when planning an infra-red 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 Figure 4.3). 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.

4.2.2

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/m2 per carrier to work without errors (resulting in a 80 dB S/N ratio for the audio channels). The effect of the

number of carriers on the coverage area can be seen in Figure 4.4 and Figure 4.5. The

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 Figure 4.6, Figure 4.7 and Figure 4.8). 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 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 infra-red light.

The texture and color of the objects, walls and ceilings also plays an important role. Infra-red 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 infra-red

signal (see Figure 4.9). With few exceptions it cannot pass through materials that are opaque

to visible light.


Integrus Planning | en 21

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 infra-red 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.

Positioning the radiators

Since infra-red 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 infra-red 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 Figure 4.10 and Figure 4.11).

Figure 4.10

Infra-red signal blocked by a person in front of the participant

Figure 4.11

Infra-red signal not blocked by a person in front of the participant

The figures below illustrate how infra-red 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.



22 en | Planning Integrus

Figure 4.12

Combination of direct and reflected radiation

Figure 4.13

Combination of several reflected signals

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 infra-red radiation from radiators positioned in front. When the direction of the receiver changes, e.g. with varying seat arrangements, mount the radiators in the corners of the room (see

Figure 4.14).

IOM-INT | V1.1 | 2010.12

Figure 4.14

Radiator position for covering seats in a square arrangement



If the audience is always directed towards the radiators, you do not need radiators at the back

(see Figure 4.15).

Figure 4.15

Radiator positioning in a conference hall with auditorium seating and podium

If the path of the infra-red signals is partially blocked, e.g. under balconies, you should cover

the 'shaded' area with an additional radiator (see Figure 4.16).

4.2.6

Figure 4.16

Radiator for covering seats beneath a balcony

Overlapping footprints and multipath effects

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).

Figure 4.17 and Figure 4.18 illustrate the effect of overlapping footprints and differences in

signal delays.

Figure 4.17

Increased coverage area caused by added radiation power

4.3

4.3.1

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 7.4 ).

Planning an Integrus infra-red radiation system

Rectangular footprints

Determining the optimal number of infra-red 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 Figure 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.

The guaranteed rectangular footprints for various number of carriers, mounting heights and

mounting angles can be found in section 12.5 . The 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 CD-ROM). 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

Planning radiators

Use the following procedure to plan the radiators:



26 en | Planning

4.3.3

Integrus

1.

Follow the recommendations in section 4.2 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 Figure 4.14, Figure 4.15 and Figure 4.16 for examples of a radiator lay out.

Cabling

Signal delay differences can occur due to differences in the cable length from the transmitter to each radiator. In order to minimize the risk of black spots, use equal cable length from

transmitter to radiator if possible (see Figure 4.22).

50m

50m

Radiators with equal cable length

When radiators are loop-through connected, the cabling between each radiator and the

transmitter should be as symmetrical as possible (see Figure 4.23 and Figure 4.24). The

differences in cable signal delays can be compensated with the signal delay compensation switches on the radiators.

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 m3 of free space around the back of the radiator. To prevent the radiator from becoming too hot, make sure that there is a good airflow in this free space.

Always ensure that natural airflow is not obstructed by ceilings, walls etc. when determining the position of the radiator. Leave plenty of space around the radiator to prevent it becoming too hot.

NOTICE!

When in operation, the radiators may feel warm to the touch. This is quite normal, and does not indicate a radiator fault or malfunction.

Attaching the suspension bracket

Figure 5.9

Attaching the suspension bracket to the radiator

First assemble the supplied suspension bracket and connect it to the radiator (see Figure 5.8

and Figure 5.9). This bracket is attached to the radiator by two bolts with washers. There are

corresponding holes on the back of the radiators. There is also a spring-loaded plunger

(indicated by a black arrow in Figure 5.9), located above the bolt hole on the right-hand arm of

the bracket, which is used for adjusting the angle of the radiator (shown in inset in

Figure 5.9). There are corresponding holes on the back of the radiator for accepting this

plunger. The mounting angle can be adjusted in steps of 15°.

The top of the floor stand is screwed into the suspension bracket (Figure 5.10). The bracket is

supplied with both metric and Whitworth threaded plates, and is therefore compatible with most standard floor stands. For floor stands, the mounting angle can be set at 0°, 15° or 30°.

Wall mounting

For wall mounting, an extra wall bracket (LBB 3414/00) is required (must be ordered

separately). This bracket is attached to the wall by means of four bolts (see Figure 5.12).

Figure 5.12

Attaching the wall mounting bracket to a wall

NOTICE!

The four bolts used to attach the bracket must each be able to withstand a pull-out force of

200 kg (440 lb). The bolts and plugs delivered with the LBB 3414/00 wall bracket are only intended for mounting the unit on a solid brick or concrete wall.

Four holes of 10 mm in diameter and 60 mm in depth must be drilled using the drilling pattern





Figure 5.13

LBB 3414/00 wall mounting bracket showing dimensions and drilling pattern

The radiator (plus suspension bracket) is attached to the wall bracket by sliding the mounting

bolt over the slot on the wall bracket and then tightening it (see Figure 5.14). A split pin is

then inserted into a small hole in the bolt to stop it from working loose (see inset in

Figure 5.14).

Attaching the radiator to the wall mounting bracket

The vertical angle of the radiator can be adjusted between 0 and 90° in steps of 15°. The horizontal orientation of the radiator can be adjusted by loosening the bolt then turning the radiator to the required position.

Ceiling mounting

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


Integrus

5.4.5

Mounting 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.


Radiators in permanent installations can be fixed to a wall, hung under a ceiling or balcony or secured to any sturdy material using the unit's built-in bracket and mounting adaptor supplied

with the radiator (Figure 5.15). In non-permanent installations, a floor stand can be used. The

mounting adaptor enables the radiator to be positioned for optimum performance.

This chapter gives an overview of typical system connections using the INT-TX range transmitter:

– Connecting the DCN Next Generation system

– Connecting the DCN system

– Connecting other external audio sources

– Connecting an emergency signal switch

– Connecting to another transmitter

Connecting the DCN Next Generation

The transmitter can be directly connected to the optical network of the DCN Next Generation conference system. Use an optical network cable to connect one of the optical network

sockets of the transmitter to the optical network (see Figure 6.1). The network mode must be

enabled with the configuration menu (see section 7.2.3 ).

6.1.2

Connecting the optical network to the modular IR transmitter

NOTICE!

See the DCN Next Generation Installation and User Instructions for more information about connecting the transmitter in the optical network.

Connecting the DCN system

The transmitter requires the Integrus DCN Interface Module (LBB 3423/20) to interface with the Digital Congress Network (DCN). This module must be mounted in the transmitter

housing (see section 5.2 ). The connections between DCN units and the transmitter are made

in a loop-through configuration via the DCN 6-pole circular connectors on the module's rear panel. See the DCN Installation and Operating Manual for more information.

When the DCN system supply voltage on the trunk input switches off, the Integrus DCN interface module automatically switches the transmitter to standby. When the DCN system supply voltage switches on, the transmitter is switched to operating mode.

NOTICE!

When the Integrus DCN interface module is used in combination with audio signals connected to the cinch inputs, the DCN and audio signals on corresponding inputs are mixed.

Connecting an emergency signal

To use the emergency signal function, a switch (normally-open) must be connected to the emergency switch connector. The reaction of the transmitter on a closed switch depends on

the configuration of the auxiliary inputs (see also section 7.2.9 ):

– If the auxiliary input is 'Mono + Emergency', the audio signal on the Aux-Right input is distributed to all output channels, overriding all other audio inputs.

– If the auxiliary input is 'Stereo' or 'Stereo to Mono', the audio signals on the Aux-Left and

Aux-Right inputs are distributed to all output channels, overriding all other audio inputs.

Setting 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.

Setting the delay switches

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.

Determining the radiator delay switch positions

As described in section 4.2.6 , 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 CD-ROM).

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 7.4.3 ).

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.


Integrus

7.4.1


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.

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

7.4.3 ).

8.

Set the delay switches to the calculated switch positions.

Figure 7.3 and Table 7.1 illustrate the calculation of the cable signal delay.

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.

Divide the signal delay difference by 33. The rounded off figure is the delay switch position for that radiator.

Table 7.2

Calculation of the delay switch positions of a system with one transmitter

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.


6.





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 7.4.3 )

9.

Set the delay switches to the calculated delay switch positions.

CAUTION!


NOTICE!

When a master-slave configuration is used for rooms which are always separated, the delay switch positions can be determined per system and the delay caused by transmission from master to slave transmitter can be ignored.

Figure 7.5, Table 7.1, Table 7.3 and Table 7.4 illustrate the calculation of the extra master-

slave signal delay.

Calculation of the delay switch positions of a system with two transmitters

Systems with more than 4 carriers and a radiator under a balcony

Figure 7.6 illustrates a situation in which a radiation signal delay occurs and which can be

compensated for. For systems with more than four carriers, add one delay switch position per

10 meter (33 feet) difference in signal path length to the radiators which are closest to the

overlapping coverage area. In Figure 7.6 the signal path length difference is 12 meter. Add one

delay switch position to the calculated switch position(s) for the radiator(s) under the balcony.

Testing 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 7.2.2 ). 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 9.3.2 ).

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 infra-red 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 infra-red 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.

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 multipath effect 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 multipath effect is causing the problem. Note that IR radiation that is reflected from a surface with a high reflectively can also cause multipath problems.

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 7.2.11 ).

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 multi path effects.

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 7.2.7 ) and re-check the reception.

Integrus Transmitter

The Monitoring sub-menu (2) on the transmitter is used to set which signal is sent to the monitoring headphone output. It can be one of the inputs, one of the channels or no signal,

see also section 7.2.2 .

Use the monitoring headphone of the transmitter to check the input audio signal in the transmitter, before it is sent to the receivers.

When the sensitivity of one of the inputs is being changed in the Setup menu (4I, 4J or 4K), or when assigning inputs to channels (menu 4D, Per Channel), the monitoring output automatically switches temporarily to that source, even when the option 'None' has been

chosen. When the headphone output is disabled (see section 7.2.12 ), the output level can

not be changed and the level indicator is not visible.

Normal operation

The receiver cannot operate when no headphone is connected. After connecting the headphone the receiver switches to stand-by mode. Push shortly on the on/off button to switch the receiver on.


Integrus Operation | en 71

The channel number is shown on the LCD display. The channel can be changed with the channel selector. Push it to the up- or down-position to increase or decrease the channel number. The highest channel number is automatically matched to the number of channels that

has been set on the transmitter (see section 7.2.4 ).

A battery symbol is visible on the display when the batteries or the battery pack is almost empty.

An antenna symbol is visible when the receiver picks up a modulated infra-red signal of adequate quality.

During short interruptions in the reception, the receiver mutes the headphones output. When no adequate IR signal is detected for more than 1 minute (e.g. when a delegate leaves the conference room), the receiver automatically switches to stand-by mode.

The volume can be changed by moving the volume control up or down.

The receiver can be manually switched to stand-by mode by pressing the on/off button for more than 2 seconds.

When the headphone is disconnected, the receiver is automatically switched off. (A switch in the headphone connector disconnects the batteries.)

The infra-red receivers can operate with disposable batteries (2x AA-size alkaline cells) or with a rechargeable battery pack (LBB 4550/00).

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 chapter 5.

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.

9.3.2

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.

Reception test mode

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: Push the channel selector to the Upposition, press the on/off button and hold both for ca. 2 seconds. When in test-mode, switch between carriers by using the channel selector. The receiver's display will shortly show the carrier number (0-7) and then a quality indication (00-90).

– These charging units are only intended to charge LBB 4540 receivers with a LBB 4550/00 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.

– When the rechargeable battery pack is used, it is advisable to check regularly after three years that the batteries are not leaking. If there is any sign of leakage or corrosion, replace the battery pack. Ensure that only the battery pack LBB 4550/00 is used. The battery pack has to be replaced at least every five years.

– Check that the charging unit is used under the specified working conditions (see technical data).

– Check that the receiver contains a battery pack which is connected correctly.

– Ensure that the receiver is at room temperature and re-insert the receiver in the charging unit.

– If the charging indicator starts blinking again, replace the battery pack and check whether the problem is resolved.

– Replace the battery pack and check whether the problem is resolved.

–

Do the tests as described in section 7.5 .
