157
| 3 - Instruction manual
Meaning of the Link Quality Indicator
The LQI (Link Quality Indicator) on the display of the receiver shows the transmission
quality for the respective channel.
On the one hand, the transmission quality depends on the field strength (RF indicator on the
receiving channel display). However, on the other hand, it also depends on external sources
of interference that cannot be identified on the RF indicator (for example, they may be on the
same frequency or a very close neighboring frequency or may not affect the RF strength).
As a basic principle, an LQI value significantly higher than 50% should be achieved for a
secure transmission.
The LQI display shows the following information:
Green range from 50% to 100%:
• No transmission errors
The transmission quality is good enough to ensure an audio quality of 100%.
Yellow range from 20% to 49%:
• Individual transmission errors: short-term error correction active
• Individual audio artifacts may be audible
There are initial transmission errors. In rare cases, there are initial audible audio artifacts.
Error correction may be active in this case.
158
| 3 - Instruction manual
Orange range from 1% to 19%:
• Frequent transmission errors: long-term error correction active
• Risk of audio drop-outs
The transmission errors increase, which means that the error correction duration also
increases. There is a risk of audio drop-outs.
Red range 0%:
• No transmission
In this range, the transmission quality is so poor that audio drop-outs can no longer be
avoided.

Link Density mode (LD mode)
LD mode doubles the number of usable carrier frequencies in the available
spectrum, as the minimum distance for the equidistant frequency grid is halved.
This is achieved by reducing the modulation bandwidth of the transmitter. This
means that a much smaller frequency spacing between neighboring frequencies
can be selected, and therefore more frequencies can be used in the same
available spectrum without intermodulation.
LD mode is recommended if the following criteria are met:
• The required number of channels cannot be achieved using the normal
mode, as there may be only a small spectrum available.
• The distance between the transmitters and the antennas is not too great.

Connecting receivers in a Dante® network
Assignment of the network connections
The network connections have a different assignment depending on the network mode set.
The network mode can be changed in the Network menu, see System -> Network menu
item.
PoE = Power over Ethernet
Ctrl = network control via e.g. Wireless Systems Manager (WSM), Sennheiser

Information
The EW-DX EM 2 Dante and EW-DX EM 4 Dante receivers are equipped with a versatile
network interface with selectable network modes for flexible signal transmission. Further
information is available on the following pages.
In compact network systems that only have a limited number of receivers, the “Single Cable”
mode is the best option. This straightforward setup simplifies the installation and reduces the
cabling workload.
214
| 3 - Instruction manual
For larger, more extensive network configurations, the “Split or Redundancy Mode” is
recommended. In these operating modes, the differing control data can be wired separately
alongside the digital audio protocol data and also allow for redundant cabling.
When integrating several switches in a network, it is important to carefully consider the
possible effects on the network performance. A selected operating mode can, if the cabling
is faulty, restrict the network operation or lead to system failure. In this respect, it is also
important to ensure that the network switches from the respective manufacturers that
are used also support the data and audio protocols (e.g. Dante) and that they have been
configured accordingly.
The Spanning Tree Protocol (STP) has been implemented to avoid misconfigurations between
network modes and cabling and the resulting broadcast storms. The STP is configured with a
priority of 57344 and should be considered when setting up a network with managed switch
so that an EW-DX EM doesn't get the route bridge. STP could be enabled or disabled.
Detailed instructions can be obtained from the respective manufacturers of the individual
software applications.
First of all, set the network mode in the receiver, see EW-DX EM 2 Dante System ->
Network menu item and EW-DX EM 4 Dante System -> Network menu item.
Note the assignment of the sockets and the wiring examples on the following pages.
The following examples do not show all of the cabling options.
Connect the cables.
Information about the Dante Controller and the Dante network protocol settings
is available on the Audinate website: audinate.com.

234
| 3 - Instruction manual
Meaning of the Link Quality Indicator
The LQI (Link Quality Indicator) on the display of the receiver shows the transmission
quality for the respective channel.
On the one hand, the transmission quality depends on the field strength (RF indicator on the
receiving channel display). However, on the other hand, it also depends on external sources
of interference that cannot be identified on the RF indicator (for example, they may be on the
same frequency or a very close neighboring frequency or may not affect the RF strength).
As a basic principle, an LQI value significantly higher than 50% should be achieved for a
secure transmission.
The LQI display shows the following information:
Green range from 50% to 100%:
• No transmission errors
The transmission quality is good enough to ensure an audio quality of 100%.
Yellow range from 20% to 49%:
• Individual transmission errors: short-term error correction active
• Individual audio artifacts may be audible
There are initial transmission errors. In rare cases, there are initial audible audio artifacts.
Error correction may be active in this case.
235
| 3 - Instruction manual
Orange range from 1% to 19%:
• Frequent transmission errors: long-term error correction active
• Risk of audio drop-outs
The transmission errors increase, which means that the error correction duration also
increases. There is a risk of audio drop-outs.
Red range 0%:
• No transmission
In this range, the transmission quality is so poor that audio drop-outs can no longer be
avoided.
236

Link Density mode (LD mode)
LD mode doubles the number of usable carrier frequencies in the available
spectrum, as the minimum distance for the equidistant frequency grid is halved.
This is achieved by reducing the modulation bandwidth of the transmitter. This
means that a much smaller frequency spacing between neighboring frequencies
can be selected, and therefore more frequencies can be used in the same
available spectrum without intermodulation.
LD mode is recommended if the following criteria are met:
• The required number of channels cannot be achieved using the normal
mode, as there may be only a small spectrum available.
• The distance between the transmitters and the antennas is not too great.

In compact network systems that only have a limited number of receivers, the “Single Cable”
mode is the best option. This straightforward setup simplifies the installation and reduces the
cabling workload.
For larger, more extensive network configurations, the “Split or Redundancy Mode” is
recommended. In these operating modes, the differing control data can be wired separately
alongside the digital audio protocol data and also allow for redundant cabling.
When integrating several switches in a network, it is important to carefully consider the
possible effects on the network performance. A selected operating mode can, if the cabling
is faulty, restrict the network operation or lead to system failure. In this respect, it is also
important to ensure that the network switches from the respective manufacturers that
are used also support the data and audio protocols (e.g. Dante) and that they have been
configured accordingly.
The Spanning Tree Protocol (STP) has been implemented to avoid misconfigurations between
network modes and cabling and the resulting broadcast storms. The STP is configured with a
priority of 57344 and should be considered when setting up a network with managed switch
so that an EW-DX EM doesn't get the route bridge. STP could be enabled or disabled.
Detailed instructions can be obtained from the respective manufacturers of the individual
software applications.
First of all, set the network mode in the receiver, see EW-DX EM 2 Dante System ->
Network menu item and EW-DX EM 4 Dante System -> Network menu item.
Note the assignment of the sockets and the wiring examples on the following pages.
The following examples do not show all of the cabling options.
Connect the cables.
Information about the Dante Controller and the Dante network protocol settings
is available on the Audinate website: audinate.com.
Information on the use of remote software is available in the download area of
the Sennheiser website: sennheiser.com/download.

311
| 3 - Instruction manual
Meaning of the Link Quality Indicator
The LQI (Link Quality Indicator) on the display of the receiver shows the transmission
quality for the respective channel.
On the one hand, the transmission quality depends on the field strength (RF indicator on the
receiving channel display). However, on the other hand, it also depends on external sources
of interference that cannot be identified on the RF indicator (for example, they may be on the
same frequency or a very close neighboring frequency or may not affect the RF strength).
As a basic principle, an LQI value significantly higher than 50% should be achieved for a
secure transmission.
The LQI display shows the following information:
Green range from 50% to 100%:
• No transmission errors
The transmission quality is good enough to ensure an audio quality of 100%.
Yellow range from 20% to 49%:
• Individual transmission errors: short-term error correction active
• Individual audio artifacts may be audible
There are initial transmission errors. In rare cases, there are initial audible audio artifacts.
Error correction may be active in this case.
312
| 3 - Instruction manual
Orange range from 1% to 19%:
• Frequent transmission errors: long-term error correction active
• Risk of audio drop-outs
The transmission errors increase, which means that the error correction duration also
increases. There is a risk of audio drop-outs.
Red range 0%:
• No transmission
In this range, the transmission quality is so poor that audio drop-outs can no longer be
avoided.

Link Density mode (LD mode)
LD mode doubles the number of usable carrier frequencies in the available
spectrum, as the minimum distance for the equidistant frequency grid is halved.
This is achieved by reducing the modulation bandwidth of the transmitter. This
means that a much smaller frequency spacing between neighboring frequencies
can be selected, and therefore more frequencies can be used in the same
available spectrum without intermodulation.
LD mode is recommended if the following criteria are met:
• The required number of channels cannot be achieved using the normal
mode, as there may be only a small spectrum available.
• The distance between the transmitters and the antennas is not too great.

Installing the EW-D ASA in a rack
NOTICE
Rack mounting poses risks!
When installing the device in a closed 19" rack or multi-rack assembly,
please consider that, during operation, the ambient temperature, the
mechanical load and the electrical potentials will be different from those
of devices which are not mounted into a rack.
Make sure that the ambient temperature within the rack does
not exceed the permissible temperature limit stated in the
specifications. See (Specifications).
Ensure sufficient ventilation; if necessary, provide additional
ventilation.
Make sure that the mechanical load of the rack is even.
When connecting to the power supply system, observe the
information indicated on the type plate. Avoid overloading the
circuits. If necessary, provide overcurrent protection.
When mounting in a rack, please note that intrinsically harmless
leakage currents of the individual power supply units may
accumulate, thereby exceeding the permissible limit value. As a
remedy, ground the rack via an additional ground connection.
To mount the antenna splitter in a rack, you will need the GA 3 rack mount kit (optional
accessory).
Rack mounting is carried out in the same way as for the EW-D EM receiver: see
Installing receivers in a rack.

• Observe the length of the cable within the antenna, see Cable sheath options.
• The DC connection is optional and provides an alternative to the DC supply via the
BNC cable.
• The EW-DX EM 4 Dante and EW-D ASA devices supply the antenna with
voltage via the BNC cable, meaning no additional DC supply is required.
• With the EW-D EM, EW-DX EM 2 and EW-DX EM 2 Dante devices, a power
supply via the DC connection is required.
The antenna is supplied with power via the RF or DC cable. As soon as the
power supply is established, the antenna switches on automatically. There is no
separate on/off switch.
To connect the cable to the antenna:
If necessary, connect the DC cable to the DC in socket.
We recommend using the EW-D power supply unit (art. no. 509454).
Run the cable out to one side.
Connect the RF cable to the RF in socket.
Run the cable out to the same side.
Alternatively, you can connect the cables through an opening in the wall.
Cable sheath options:
The cable sheath enables optimum antenna characteristics and also enables a plastic cable
duct to be laid to discreetly conceal the cables directly up to the antenna housing.
• A RF cable length in the antenna >205 mm
• B RF cable length in the antenna >110 mm
• C RF cable length in the antenna >140 mm
