5 WORKING PRINCIPLES
IQOYA X/LINK-MPX allows the following use cases:
At the studio side
● Encoding of one MPX IP stream from an analog MPX input or the digital MPX input,
● and decoding of a return IP audio stream to the analog outputs.
Note that the decoded audio is also available from the AES3 output, but at 192 kHz.
At the FM transmitter site
● Decoding of an IP MPX audio stream to the analog MPX and digital MPX outputs
● And encoding of a return IP audio stream from the analog inputs.
The two diagrams below show X/LINK-MPX used as an IP MPX encoder, and X/LINK-MPX used as an IP MPX decoder.
14

IQOYA X/LINK-MPX user manual
5.1 Audio inputs and outputs
An MPX input receives the MPX signal to be encoded. It can be analog, or AES192. The selected source can be encoded in
PCM and in µMPX, and streamed to several destinations.
The MPX signal decoded from an IP MPX stream is available on the 2 analog MPX outputs and on the AES192 MPX output.
Audio inputs receive an analog audio signal to be encoded, typically to send an audio monitoring stream; the audio signal
decoded from a received IP audio stream is available from the two analog audio outputs.
See paragraph Audio I/O −> Input −> settings to configure the inputs.
See paragraph Audio I/O −> Output −> settings to configure the outputs.
5.2 Programs
On the encoding section of IQOYA X/LINK-MPX, a program is the encoding of one MPX input or two mono audio inputs or
one stereo audio input. A program is then defined by the following parameters:
● the audio mode: mono, stereo. MPX is always mono.
● 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.
15

IQOYA X/LINK-MPX user manual
On the decoding part of IQOYA X/LINK, a program is the decoding of an audio or MPX source to the audio or MPX outputs.
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),
● audio inputs,
● sound files or playlists stored locally.
For an output program defined to output an MPX signal, possible sources of a decoding priority can be:
- RTP IP stream carrying PCM MPX
- IP stream carrying µMPX format
- 192 kHz MPX sound file stored on a local SDHC card
5.3 IP services
IP services are the way programs are streamed over the IP network.
An IP service can be sent to one IP destination (unicast or multicast), or several IP destinations (multi-unicast or
multi-multicast). The main parameters that define an IP service are:
● the streaming protocol: RTP for audio or uncompressed MPX, UDP for µMPX)
● the FEC scheme (except for µMPX which FEC is selected in the Program).
● the destination IP address and port. Several destination IP addresses and ports can be declared (multi-unicast /
multi-multicast).
When IQOYA decodes, it listens to IP services and unpacks the IP frames in order to extract and decode the audio contents.
6 INSTALLATION
6.1 Grounding IQOYA X/LINK-MPX
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 (protective earth) and building’s PE must be connected (use of a socket outlet with PE is required).
The sockets outlets to which the equipment is connected must be easily accessible.
Once IQOYA is installed and properly grounded, you can connect the Eth ports and audio I/Os as required for your
installation.
6.2 Connecting IQOYA X/LINK-MPX to the network
We recommend that the first connection to the IQOYA codec is done on a LAN. The default IP addresses of IQOYA X/LINK
Eth ports are:
● Eth1: 192.168.0.100
● Eth2: 192.168.1.100
● Eth3: 192.168.2.100
● Eth4: 192.168.3.100
In case you do not know the IP addresses of the IQOYA X/LINK unit you want to connect to, you can read its IP addresses
from the front panel (see paragraph “LCD display and keypad”).

IQOYA X/LINK-MPX user manual
Make sure all other devices connected to this LAN are in the same subnet and have different IP addresses (this includes the
PC from which you will connect to the IQOYA codec to configure).
WARNING:
● Eth1, Eth2, Eth3 and Eth4 must belong to different subnetworks.
● Eth1, Eth3 and Eth4 are Gbits interfaces.
● Eth2 is a 100 Mbits/s interface.
6.3 Enabling / disabling the hardware bypass function
IQOYA X/LINK-MPX allows for the hardware bypass of the analog audio inputs to the analog audio outputs, and of the MPX
AES input to the MPX AES output in case of power supply failure.
Enabling / disabling the hardware bypass
6.4 Powering up IQOYA X/LINK
It is recommended to establish all connections before powering up the device.
IQOYA X/LINK features two internal hot swappable redundant power supply units. It is recommended to connect the two
power cords. However, only one cord may be used.
IQOYA X/LINK starts as soon as it is connected to the mains.
6.5 Steps to follow to configure IQOYA X/LINK
Set the global parameters of your IQOYA X/LINK
Encoding:
● Adjust the parameters of the MPX input or analog audio inputs: type (analog, AES) and gain.
● Declare the programs (encoding formats)
● Declare the IP services to be streamed over IP (IP audio streams)
Decoding:
● Adjust the parameters of the outputs: type (analog, AES), and gain.
● Declare the IP services to be received from the network (IP audio stream)
● Declare the output program(s)
●Check the status and metrics on the output programs.
