4.4 Getting started
The XIRIUM PRO system makes it possible to replace conventional cable connections between audio
sources and audio sinks (referred to in short as "peripheral devices" below) with a robust radio connection.
With just 2 devices, the transmitter (TX) and the receiver (RX), an audio signal can be transmitted
quickly and cost-efficiently. The XIRIUM PRO system transfers audio signals (LINE level) as well as
digital audio signals (AES or DANTE) in studio quality with an extremely low latency time.
9 channels in the 5 GHz band are available for transmitting the audio signal. Up to two audio signals
can be transmitted in one RF channel with no loss to audio quality. The distance between transmitter and receiver can be more than 3200 feet.1 The actual distance between transmitter and receiver
depends on the specific environmental conditions (line of sight, obstacles in the link, reflections,
external RF signals, etc.).
Depending on the distance between transmitter and receiver, the transmission power may be manually controlled using the associated app in order to ensure the RSSI level remains in the "green range".
In order to be able to establish a connection between TX and RX, the devices must be separated by
a distance of at least 10 feet (using 6 dBi antenna and transmission power set to -3 dB).

The XIRIUM PRO system has been designed with features to simplify use. Understanding these features will be helpful before the system is put into operation.
This refers to one of the UNII-3 band channels only, since the lower channels of the UNII-1 band have a lower approved
transmission power.
The app takes care of the maximum EIRP setting as soon as you choose a different RF channel!

Description of product
4.4.1 App
The app is the central control interface of the XIRIUM PRO system. Using the app, transmission paths
and networks can be created and managed. The app provides information about the current status
of the connected devices and transmission paths. The XIRIUM PRO devices can be connected to the
app through 2 modes:
Network mode
Several devices connected to the app via an
access point.
Stand-alone mode
Only 1 device is directly connected
to the app.
It is highly recommended to choose a 2.4 GHz channel according to prior agreement with
event management. Uncoordinated usage of the 2.4 GHz channel may lead to connectivity
issues in the 2.4 GHz transmission path due to high traffic. The audio transmission is not
affected by the 2.4 GHz transmission path!
4.4.2 Repeater
A "repeater" is an RX equipped with a repeater module. The repeater is used in the following situations:
•• Stabilizing transmission paths
The repeater receives the signal from the TX and transmits a redundant signal to the RX. The
redundant signal stabilizes the connection and reduces efferts caused by interferences.
•• Overcoming obstacles
If no line-of-sight connection is possible, obstacles such as walls, glass or even corners can be
overcome with the repeater.
•• Extending distances
When a repeater is used, the distance between TX and RX can be doubled.

OVERLOAD

4.4.3 Signal quality bar
The signal quality bar displays both RSSI level and packet loss. The scale of the bar refers to the RSSI
level (Received Signal Strength Indicator). It is recommend to have an RSSI level not appearing in the
“low” and “overload” area.
The color of the bar displays the packet loss:
•• Bar is displayed green: packet loss is low
•• Bar is displayed orange: packet loss is critical
•• Bar is displayed red: packet loss is high.
A high packet loss increases the probability of losing audio.

User Manual – XIRIUM PRO® CA | BDA 471 2017/03
Description of product
Examples
•• RSSI level received from the TX is critical.
•• The packet loss received from TX and RP is low.
We recommend to increase the transmission power of
the TX.
•• RSSI level received from TX and RX are OK
•• The color of the bars indicate a high (TX) and a critical
(Repeater) packet loss.
We recommend to relocate the devices and / or change
the RF channel.
An improper RSSI level can be modified by increasing or decreasing the transmission power.
If the packet loss is high, the position of the devices have to be modified. Double-check if
there are other devices operating on the some channel and change the RF channel.
4.4.4 Transmission power
Depending on the application, the transmission power should be adjusted with the app so the RSSI
level on the receiver remains in the recommended range. However, the 10-foot minimum distance
between the TX/RX must always be maintained. This minimum distance applies when the 6 dBi antenna and a transmission power of -3 dB are used. If the 9 dBi antenna and/or a higher transmission
power are used, the minimum distance increases.
Decreasing transmission power
In indoor areas and over short
distances.
Increasing transmission power
In outdoor areas and over longer distances.

4.4.5 XROC mode
If only 1 audio signal per RF channel is needed, we recommend using XROC mode. XROC stands for
"Extreme Ruggedized One Channel“. In XROC mode, only 1 audio signal at 6 Mbit/s is available for
each RF channel. The connection between the devices is much more stable in XROC mode, because
external influences do not interfere with the RF signal between the XIRIUM PRO devices as much.
External influences include strong reflections of the RF signal in a room or from buildings, or external
signals. The power consumption of the devices is higher in XROC mode.
LOW
-80
OVERLOAD
-70
-28
-25
The increase in the performance range is illustrated in the RX signal quality bar, which displays a
smaller “low” area when XROC mode is used.
If XROC mode is enabled on a TX, only audio channel 1 is being transmitted. Therefore a
linked RX will have no audio on channel 2.
4.4.6 Antennas
XIRIUM PRO uses omnidirectional antennas with fixed vertical radiating angles. Neutrik offers two
different antennas: the standard 6 dBi antenna, featuring a 25° vertical angle, and an optional
9 dBi antenna with a 12.5° vertical angle.
6 dBi
9 dBi
25° vertical
360° horizontal
12.5° vertical

For pure receivers Neutrik recommends to use
a directional antenna. It helps focusing on the
TX signal and avoids disturbances from other
systems. There's an N-type adapter provided with
the antenna to mount it directly on the device.

4.4.7 Remote antennas
If the 5 GHz antenna and the 2,4 GHz antenna need to be aligned differently in terms of angle, it’s
advisable to remote the 5 GHz link. For that purpose Neutrik offers an antenna cable (NKXPA-5) with a
length of 5 meters and an attenuation of 4 dB. There is also an additional directional antenna available
for such applications having a gain of 18 dBi. This antenna must be used only for pure receivers and
not for any transmitting device, hence also not for a repeater. Like all other XIRIUM PRO antennas this
antenna has a vertical polarization. It is necessary to gear this antenna in the correct angle towards
the TX antenna. A correspondent graphical indication can be found on the backside of the antenna.

4.4.9 Line-of-sight and redundant RF path
For a reliable wireless audio link, make sure all XIRIUM PRO devices have a line-of-sight connection.
If a line-of-sight connection cannot be established, the receiver may be in a drop-out zone. A dropout zone is a point where phase cancellation occurs between the direct signal and the deflected one.
Relocating the transmitter (TX) and/or receiver (RX) can help eliminate this phase anomaly. Using a
repeater can also eliminate the problem of the drop out zone. A repeater effectively provides a redundant RF path to all receivers within range. The RX receives identical audio signals from both the
transmitter and repeater.

4.4.10 Antenna height + distance
Consider the Fresnel zone, which is an ellipsoidal area between wireless devices. For XIRIUM PRO
TX and RX devices, there should be no obstacles within the Fresnel zone. Maintaining proper
antenna height is essential to ensure trouble-free communication between XIRIUM PRO devices. To
define an area that is free of obstacles, use the following chart to estimate proper antenna height.

4.5 Selecting transmission channels
4.5.1 Automatic selection of transmission channels
A TX is assigned to channel 149 by default. If channel 149 is already occupied by a different TX, the
device searches for the next free channel. The TX saves the last channel used. When switched on
again, the TX uses the last channel used, as long as it is not occupied. If the TX changes the channel,
all devices in the transmission path are assigned to the new channel.
4.5.2 Manual selection of transmission channels
The transmission channel can also be manually adjusted with the app. To guarantee a trouble-free
process, the app prevents an adjacent channel from being selected. The transmission channel can
be changed on the Edit page. More information in Section "Changing the transmission channel"
on page 40.
