Concept And Design

Lingua Infrared (IR) is Televic Conference's wireless solution for language distribution using infrared. You

can combine this system with Plixus engines or another third-party system to feed the floor and interpreter

audio to the Lingua IR. Link this audio source to the Lingua IR transmitter through a Dante™ connection.

The transmitter will send the audio signal to the radiators inside the room. The radiator will then send the

audio signal as infrared radiation to the receivers present in the room. These will then convert the radiation

back into an audio signal. Finally, with the receiver the participant can use which languages they wish to

hear.

Figure 1-1 A typical Lingua IR setup where one ore more audio sources (such as a conference system) are used to

feed audio into the infrared system. Participants present in the room can listen to the audio they want using the

receivers that pick up the infrared radiation.

AB O U T L ING U A I R 9

Lingua IR consists out of four parts:

Lingua T (transmitter): accepts the audio signal from the conference system (for example

Plixus) and transmits the signal to the radiator(s). By default you can transmit up to 6 channels,

however additional licenses are available to transmit 12 (Lingua L12) or 40 channels (Lingua

L40).

Lingua RAD_H (radiator): distributes the signal throughout the conference venue.

Lingua Rx (receiver): allows attendees to select the language they want to hear the speaker

in. Three variants are available to receive 6, 12 or 40 channels.

Lingua CHC (charging case): case to charge and transport receivers in.

INSTALLATION DESIGN

This chapter describes how to set up the installation of the Lingua IR system before

you can physically install it. You will find more information on the technical details

of the different components and how to combine and configure them.

GENERAL INFRARED GUIDELINES

270°

Rules And Standards

The Lingua IR systems conforms to IEC 61603 part 7 (for 24 channels), the international standard for digital

infrared transmission of audio signals for conference use and similar applications.

Infrared Bands And Channels

The Lingua IR system can use a maximum of ten infrared bands, each band can have up to four

channels. The maximum amount of channels on your system depends on the license you have (6, 12 or 40

channels).

Infrared Influencing Elements

SENSITIVITY OF THE RECEIVER

The positioning of the receiver relative to the radiator(s) has an effect on how efficiently you will receive a

signal. For maximum sensitivity aim the back side of the receiver (the side with the clip) directly towards the

radiator. When you tilt the receiver this will reduce the sensitivity of the receiver. The receiver has a 270°

wide reception angle.

Figure 1-7 The reception angle of the Lingua IR receiver

AMBIENT LIGHTING

Ambient lighting can disturb the distribution of the infrared signal. For this reason the Lingua IR system

should not be used in outdoor conditions or in rooms with very bright lightning.

GEN ERA L INFRA R ED G U ID ELIN ES 34

VENUE PROPERTIES AND RADIATOR POSITION

Different elements present in the room can effect the infrared signal transmission. Most objects reflect

infrared, with the exception of dark and rough surfaces that absorb a large portion of the infrared signal.

Infrared will not pass trough objects that are opaque to visible light, therefore it is important to position your

radiators carefully.

Do not put objects between the radiator and the receivers because this will hinder the infrared

signal. This also applies to people, the radiation will not pass through people. Therefore you should

position enough radiators at the correct locations inside the venue for optimal coverage.

Figure 1-8 Effect of positioning the radiator too low, preventing people sitting in further rows from picking up

the infrared signal

Figure 1-9 Correct position of the radiator, participants on all rows can pick up the infrared signal

If the venue permits it, the receiver can pick up reflected infrared radiation as well as direct radiation. The

radiation can be reflected by the wall, floor or other objects present in the room.

GEN ERA L INFRA R ED G U ID ELIN ES 35

Footprint Of The Radiator

Height

Every radiator has a certain reach. This is the area that can receive the infrared radiation, this is called the

footprint of the radiator. The footprint of the radiators depends on the position of the radiator as well as the

amount of channels used.

Figure 1-10 The footprint of the radiator and the physical parameters that influence the footprint

The position of the radiator is determined by the following parameters:

The x position in the room

The y position in the room

The height of the mounted radiator

The vertical angle: how the radiator is tilted

The horizontal angle: the angle the radiator is turned left or right

For a detailed description of how these parameters effect the footprint see "Position the Lingua IR

components" on page38.

The amount of channels can also change the footprint of the radiator. When you have more than four,

eight, twelve, etc. channels, this will drastically reduce the size of the radiator footprint.

OVERLAPPING FOOTPRINTS

When there are multiple radiators in a room, the footprints of the different radiators can overlap. If these

radiators are connected to the transmitter with cables having different lengths then the signal will reach the

radiators at a different time. This mismatch will results in the reduction or canceling of the infrared signal (in

places where the IR signal of the radiatiors have equal strength), thus creating black spots. For more

information see

GEN ERA L INFRA R ED G U ID ELIN ES 37

POSITION THE LINGUA IR COMPONENTS

Lingua IR Radiator Position

The position of the radiators is very important for a successful set up. Depending on the layout of your room,

the radiators need to be set up in different places of the room. Below you can find some examples of

different setups and the position of the radiators.

To see the effect of the position and angle of all radiator on the footprint of the radiators and the IR

reception in the room, use the calculator tool. You can find the calculator on Sharefile in the folder

TCS-Marketing > Public > Technical Documentation > Calculators.

In the first example all seats are pointing towards the stage in the same direction. In order for everyone to

receive the infrared signal, you need to place two radiators in two corners of the room to cover the entire

room (by reflected and direct radiation).

When the length of the cables from the transmitter to the radiators differs, then this difference

should be corrected using the automatic delay line calibration.

Figure 1-12 Conference setup with all chairs pointing in the same direction

PO S IT IO N THE L ING UA IR C O MPO NEN TS 38

In cases where beam width is an issue, you can position multiple radiators on a cluster. The loop

through the different radiators in the cluster should be done with a short cable (1m).

For rooms where the rearrangement can change or rooms where seats are positioned concentrically,

radiators should be present in every corner of the room.

Figure 1-13 Position of the radiators in a concentrically organized room

In case of rooms with a balcony, an additional radiator needs to be present under the balcony to ensure the

transmission of the signal to the seats under the balcony.

Figure 1-14 Radiator setup for room with a balcony. The balcony blocks all radiation therefore you should place

an additional radiator below the balcony to extend the signal to the people sitting below the balcony.

One of the benefits of the Lingua IR system is that you can combine different components of the system

with those of other party systems. The table below shows which functions are compatible with other

systems.

COUPLE LINGUA IR COMPONENTS

Introduction

Lingua IR is specifically designed for the wireless language distribution. You need to connect the Lingua IR

system with another system, such as a conference system, to feed the audio channels that needs to be

transmitted. You can connect to different systems, below you can find a description of how to couple the

Lingua IR components and how to connect to an external system.

Couple Transmitter And Radiators

Connect the radiators to the transmitter to send out the infrared signal. One transmitter can feed multiple

radiators. When you couple the radiators to the transmitter, you should keep the following rules in mind:

Only use 75 Ohm coax cables (RG59) with well crimped BNC connectors

You can daisy-chain a maximum of 20 radiators on one port (a total of 80 radiators per

transmitter)

The total cable length per port should not exceed 1 km

You also have the option to use multiple transmitters in one system. To connect the different

transmitters use the LAN connections on the transmitters.

Connect Lingua IR System To A Network

Lingua IR is configured with a web server. Therefore the transmitter and charger needs to be connected to a

network. Use an LAN cable and the LAN connection available on the different computers.

It is possible to daisy chain different charging cases. When using 125V a maximum 3 charging cases can be

daisy chained, when using 230V this amount is 6.

Connect To A Conference System

The Lingua IR system was designed to make it possible to connect to different conference systems to input

audio channels for transmission. Below you can find a detailed description of how to connect the different

conference systems to the Lingua IR transmitter.

You need to feed input into the Lingua IR system to broadcast this content to the receivers. One option is to

use the audio from your Plixus conference system.

In a typical conference setup some delegates have a microphone and can join the discussion, others are

passive participants that can hear the meeting in the language they prefer. Interpreters provide these

languages with the Lingua Interpreter Desk. Transfer the languages from the Plixus system to the Lingua IR

system over Dante. The radiator can then transmit the infrared signal with these languages to the

receivers in the room.

Use the Dante™ connection on the engine and the transmitter to couple both systems. After connecting

both systems, you still need to configure the Dante™ routing as described in "Set up Dante™" on page57.

It is possible to connect with conference system from other manufacturers that provide a Dante™ on their

system. Simply connect the conference system to the Lingua IR transmitter using an LAN cable together

with the Dante™ connections on the devices. Configure the Dante™ routing as described in "Set up

Dante™" on page57

CONNECT TO CONFERENCE SYSTEM WITHOUT DANTE

When you have an analog conference system you can still connect it to the Lingua IR system: for this you

need an analog IN to Dante™ converter. Connect the analog systems to the break-in converter and then

connect Dante™ to the Lingua IR system.

Connect To An Emergency Signal

To connect the transmitter to an emergency signal system, connect a switch (normally open) to the

emergency switch connector (AUX Right). When the switch closes then the emergency signal from the AUX

R input will override all other audio input on all channels.

Figure 1-25 Where to connect the emergency signal system

Connect To An Audio Installation

When you want to connect an external audio system to the Lingua IR system to for example play music until

the meeting starts. Connect the audio system to the AUX IN L and make sure to close the left switch of the

connector.

Prepare The System For Dante™ Configuration

If your setup requires more than 11 languages see the procedure described in "Set up Dante™

routing with more than 11 languages" on page59

If you use the Plixus network with Core functionality, you need to activate the option

Automatically route interpretation channels to Dante in the Plixus Core web server. With

this option all interpretation channels will automatically be assigned to a Dante™ channel.

Note that this option is only available when your setup has 11 languages or less.

When you connect the Lingua IR transmitter to another conference system with Dante™, you need to

configure some settings before you can use the system. To configure these settings you have to connect all

devices to same network. Use a network switch to connect the central unit of the conference system, the

Lingua IR transmitter and the computer running the Dante™ controller (you can download this from the

Audinate website).

Figure 1-28 All Dante™ devices need to be connected before you can configure the Dante™ routing

SE T U P D ANTE™ 57

Make sure your computer does not have a fixed IP address. A Dante-enabled device

connected to a network will automatically setup its own network configuration, including its IP

address.

If the network has a DHCP server, which may be the case for installed networks, it will receive its

IP configuration using the standard DHCP protocol.

On a network without a DHCP server, which may be the case for temporary or smaller networks,

the Dante-enabled device will automatically assign itself an address using link local protocols, in

the same way PCs and printers often do.

Configure Dante™ Routing

Once the Dante™ devices are connected, you need to route the Dante™ channels from your input system

to the Dante™ channels of the transmitter.

Figure 1-29 How to route the output from the conference system to the input of the Lingua IR transmitter

The Routing tab of the controller shows all Dante™ devices with their inputs and outputs. The top part

shows the outputs. Here you can find the output from your conference system (1). The bottom part on

the left hold all inputs together with the Dante channels of the transmitter (40 channels) (2).

SE T U P D ANTE™ 58

Now link the output of the conference system to the input channels of the transmitter using the

matrix (3). Do this by checking the box where the input and output intersect. A checkmark appears when

the routing was successful.

Once you finish the configuration of the routing, this configuration is remembered on every Dante™ device.

Therefore you can remove the network switch and connect the transmitter to the central engine directly.

Set Up Dante™ Routing With More Than 11 Languages

In Plixus Core it is only possible to configure up to 11 languages. If your setup requires more than 11

languages you need CoCon Interpretation and CoCon Audio Routing to configure the languages that

will be available on the Dante™ channels. Use CoCon Interpretation to set up your languages and

booths.

In CoCon Audio Routing you can configure which input language to route to which output channel of the

microphone unit. Every input language you then also need to route to a Dante™ output channel, these will

then be available on the receivers.

TEST RADIATOR COVERAGE

Best Practices For Good Infrared Signal Reception

There should be no objects between the receiver and the transmitter.

Do not attach any kind of object, such as the headphone cord or a sticker, on the top of the

receiver where the infrared sensitive diode is located.

Test The Coverage Area

After installation you need to test the coverage of the transmitter in the room itself.

1. Configure the channels as described here .

2.

Activate the test tone on the transmitter using the web server ( see ).

3. Plug in headphones to activate the receiver.

4. Test the reception quality in all positions and directions. Go around the room and test all positions

that should receive the infrared signal using the test tone.

Causes For Bad Infrared Reception

RADIATOR TRANSMISSION

One option for the lack of reception is that you are testing an area that is not covered by the footprint of the

radiator. Another reason is the presence of objects between the radiator and the receiver that block the

infrared radiation. This could be structural elements such as balcony, poles or beams.

BLACK SPOTS

When the infrared system has multiple radiators which use different cable lengths, the signal will reach the

radiators at different times. As a consequence the radiation from the different radiators can cancel each

other out. Solve this by using the automatic delay line compensation (). It is possible that you may need

to tune these settings a little inside the room.

Typically you can identify a black spot as an area of bad reception that only occurs along a specific line

and/or rotating the receiver into another direction will restore the reception. Confirm this type of

interference by turning of one of the radiators. Typically higher bands are more sensitive to black spots.

IR radiation that is reflected by highly reflective surfaces can also cause black spots.

TE ST RA DIATO R CO V E RAG E 60

INTERFERENCE

CONFIGURATION

This chapter describes how to configure the Lingua IR system using the Lingua IR

web server.

CONFIGURE IP SETTINGS

Before you start using the Lingua IR web server you need to configure your local IP settings to be able to

access the web server. Follow the procedure below to configure this.

To be able to access the web server your computer needs an IP address and subnet mask that can access

the IP address of the engine. The default IP address of the transmitter is 192.168.0.140 and of charging

case 192.168.0.150, which means the computer should have an IP address that is within the same subnet,

like 192.168.0.200. The subnet mask must be the same for all equipment on the network, being

255.255.255.0.

Delay Line Compensation

When two or more radiators have overlapping footprints then the signal of these radiators can cancel each

other out in the overlapping areas. This is the case when the length of the cable differs between the

different radiators, due to the delay of the signal ( ) over the cable. This can lead to black spots, where

you are unable to receive the infrared signal of the radiators using the receivers.

Figure 6-2 The relation between the delay of a signal in the cable and the signal picked up by the receiver. When

+

the infrared signals of the radiators are asynchronous, they cancel each other out. As a result the receiver will

have no audio.

To prevent this effect you need to compensate for this delay. This means that the radiators need to send

their signal at the same time of that of the slowest radiator, delaying their signal until the slowest radiator

receives the data. The slowest radiator is the one which has the longest cable between the transmitter and

the radiator.

Figure 6-3 After delay line compensation the radiator halts the transmission of its infrared signal until the

slowest radiator also receives the signal.

The Lingua IR system has an automatic delay line compensation mechanism where the software measures

the delay based on pulses it sends over the cable. Based on the results it will specify the delay as a multiple

of 25ns (for 71.98.0223) or 12,5 ns (71.98.0220). The web server will also give a visual representation of all

radiators and their distance to the transmitter.

1.

Define the Nominal velocity of propagation, this is the speed at which data signals travel down

the cable expressed as a percentage of the speed of light in a vacuum. This value should be

indicated on the datasheet of the cables you are using. A typical value for this type of cable is 65%.

If no detailed value can be found it is save to use this value.

2.

Click Save nominal velocity of propagation.

3.

Click Open initialization to configure the delay line compensation.

4.

To start the calibration click Start automatic calibration. A progress icon will show that the

calibration process is ongoing. Select the check box below the port number to enable this port.

5. Once calibration is ready the web server will show a visual representation of the setup and its

transferred values. Older versions of the radiator are indicated by an asterisk (71.98.0223).

6.

Click Close initialization.

7. Test the audio reception in the room using the Lingua IR receiver and check whether there is full

coverage.

DELAY LINE COMPENSATION CALIBRATION RESULTS

When the calibration is ready, you get an overview of all radiators per transmitter port. Per radiator you can

adjust the delay line compensation as well as the power level. However, when you have a previous version

of the radiator (71.98.0223) it is not possible to change the power level (it is greyed out). These radiators are

indicated by an asterisk *.

Select Infrared Bands

When you use infrared, sometimes interference from other systems using the same frequency can occur. In

these cases you can disable bands.

On the Radiator page of the web server go to Disable occupied infrared bands, where you can disble

infrared bands to avoid interference from other systems that use the same infrared band such as IR wireless

microphones. Select those bands you want to disable and select Save settings.

CO NF IG U R E R A DIA TO R SETTIN G S 79

Figure 6-6 Configure infrared bands using the Lingua IR web server

Infrared Band Gains

With this setting you can configure the gain of individual infrared bands (see figure Figure 6-6 ). There are

two options available:

Default: flat gain configuration, meaning no gains are set on the radiated bands.

Custom: when you select custom and do not upload a file, the radiator uses optimized radiated

band gains. The radiator has built-in values optimized explicitly for optimal performance of an

end-to-end Televic system (compensating for frequency response characteristics). In case of

high channel counts (>12 audio channels), this will ensure that equal reception for all audio

channels.

When your system contains third-party equipment, or you want to finetune the infrared band

gains, you can upload a settings file containing the desired band gain values.

The settings file to define the custom band gain should have the extension .tir_bc. You can export

the current gain settings and use these as reference to create a custom file.

When you upload a settings file with custom values, you do not return to the Televic optimized

settings when you remove these values. To obtain these built-in settings, you need to upload a

settings file containing these Televic optimized band gain values.
