Note regarding the presentation of this document:
IQOYA X/LINK devices feature two modes of use :
● The ‘Program Distribution’ mode of use
● And the ‘Remote Broadcasting’ mode of use
These two modes are described in the WORKING PRINCIPLES chapter.
In this document, the chapters specific to the "Program Distribution" mode of use are presented
with a green background and the chapters specific to the "Remote Broadcasting" mode of use are
presented with a blue background. The chapters which are relevant for both modes of use are
presented on a white background.

Cleaning
Clean only with a soft, dry cloth. If necessary, after
disconnecting the unit’s cables, wipe it with a soft cloth
dampened with mild soapy water, then with a fresh
cloth with clean water. Wipe dry immediately with a dry
cloth. NEVER use benzene, aerosol cleaners, thinner,
alcohol or any other volatile cleaning agent. Do not use
abrasive cleaners, which may damage the finish of
metal or other parts.
Refer all servicing to qualified service personnel.
Servicing is required when the apparatus has been
damaged in any way, such as power supply cord or
plug is damaged, liquid has been spilled, the apparatus
has been exposed to rain or moisture, does not operate
normally, or has been dropped.
Moving the device
Before moving the unit, be certain to disconnect any
cables that connect with other components.
Nettoyage
Nettoyez uniquement avec un chiffon doux et sec. Si
nécessaire, après avoir débranché le cordon
d'alimentation, essuyez-le avec un chiffon doux
humidifié avec de l´eau savonneuse puis rincez-le à
l´aide d' un chiffon propre et d'eau claire.

IQOYA X/LINK range user manual
In order to guarantee compliance with the above standards in an installation, the following must be done:
● the provided cables must not be modified.
● additional cables used must have their respective shield connected to each extremity.
● Attach a ground wire to the chassis (ideally the ground wire has a ring terminal). Connect the other end of the ground wire to a good electrical
ground point.
● The equipment’s PE and building’s PE must be connected (socket outlet with PE required).
● The sockets outlets to which the equipment is connected must be easily accessible
● The maximum altitude to comply with the above standards is 2000m. IQOYA can however operate at higher altitudes.
The limits specified in the standards are designed to provide reasonable protection against harmful interference in an industrial installation. This equipment
generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instruction, may cause harmful interference to
radio communications. However, there is no guarantee that interference will not occur in a particular installation.
If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is
encouraged to try to correct the interference by one or more of the following measures:
● reorient or relocate the receiving antenna.
● increase the separation between the equipment and the receiver.
● connect the equipment into an outlet on a circuit different from that to which the receiver is connected.
● consult the dealer or an experienced audio/television technician for help.
Note:
Connecting this device to peripheral devices that do not comply with CLASS A requirements or using an unshielded peripheral data cable could also result
in harmful interference to radio or television reception. The user is cautioned that any changes or modifications not expressly approved by the party
responsible for compliance could void the user’s authority to operate this equipment. To ensure that the use of this product does not contribute to
interference, it is necessary to use shielded I/O cables.

4 WORKING PRINCIPLES
IQOYA X/LINK features two modes of use :
● The ‘Program Distribution’ mode of use: In this mode, the available functions and the graphical user interfaces are
suitable for the needs of fixed installations like STL and SSL links, delivery of WEB radios to CDNs, program delivery
to DVB/cable operators, IP audio transcoding, etc ...
● The ‘Remote Broadcasting’ mode of use: In this mode, the available functions and the graphical user interfaces are
suitable for the needs of temporary audio over IP connections like live remote broadcasts, intercom, etc ...
At first power up, the user is prompted to choose the mode of use either from the front panel (except IQOYA X/LINK-LE) or
from the configuration web interface. Later it is possible to switch from one mode to another from the configuration web
pages.
4.1 Working principles in “Program Distribution” mode of use
4.1.1 IQOYA X/LINK-ST & X/LINK-LE
IQOYA X/LINK allows at the same time:
● Encoding two audio channels in multiple audio formats, and streaming over IP
● Decoding IP audio streams to two output channels
● Transcoding IP audio streams (optional)
Schematic diagram of IQOYA X/LINK-ST & X/LINK-LE
4.1.2 IQOYA X/LINK-DUAL
IQOYA X/LINK-DUAL allows at the same time:
● Encoding four audio channels in multiple audio formats, and streaming over IP
18

IQOYA X/LINK range user manual
● Decoding IP audio streams to four output channels
● Transcoding IP audio streams (optional)
Schematic diagram of IQOYA X/LINK-DUAL
4.1.3 IQOYA X/LINK-AES67
IQOYA X/LINK-AES67 allows at the same time:
● Encoding 16 audio channels in multiple audio formats, and streaming over IP
● Decoding IP audio streams to 16 output channels
● Or transcoding IP audio streams (optional)
19

IQOYA X/LINK range user manual
Schematic diagram of IQOYA X/LINK-AES67
4.1.4 Audio inputs and outputs
The audio inputs receive the audio signals to be encoded. They can be analog, or AES/3, or LAN audio (RAVENNA or
AES67 or Livewire). Each source can be encoded several times at different formats, and streamed to several destinations.
Audio samples decoded by X/LINK are played to the selected audio output. An audio output can be analog, or AES/3, or
LAN audio ( AES67 or RAVENNA or Livewire) .
Note that decoded audio samples can also be sent to internal audio buses, and audio buses can also be sources to be
encoded. This optional feature is used for transcoding IP audio streams.
4.1.5 Programs
In the encoding section of IQOYA X/LINK, a program is the encoding of one or several audio inputs. A program is then
defined by the following parameters:
● the audio mode: mono, stereo, multi-channel.
● the audio inputs that receive the signal to be encoded. The number of inputs is given by the audio mode. Stereo
and multi-channel modes refer to consecutive inputs.
● the audio format: algorithm, bitrate, sampling frequency.
On the decoding part of IQOYA X/LINK, a program is the decoding of an audio source to the audio output. A program can
be composed of three decoding priorities, with automatic switching from a priority to another in case the audio source is
lost. Audio sources of the decoding priorities can be:
● an RTP stream (raw RTP),
● a HTTP stream (Icecast/Shoutcast),
● audio inputs,
● sound files or playlists stored locally.
