Setting Gain  
Adjust gain at the receiver so that the average signal levels are solid green and yellow with peaks that occasionally trigger the red overload LED. Attenuate  
the gain if the signal overloads repeatedly.  
Set the XLR output to line-level when possible to optimize sound system noise performance.  
System Gain Control  
The gain control on the receiver sets the audio signal level for the entire system. This allows adjustments to be made during a live performance. It is not  
necessary to change the gain on the transmitter (mic offset) to optimize the gain structure. Any required changes to gain should be made from the receiver.

High Density Mode  
Frequency Diversity  
Frequency Diversity is an advanced ULX-D receiver feature that safeguards  
against loss of audio signal caused by RF interference or by power loss in a  
transmitter.  
High Density mode creates additional bandwidth for more channels in  
crowded RF environments. Frequency efficiency is optimized by running  
at 1 mW RF transmit power and narrowing the modulation bandwidth,  
allowing for the channel spacing to be reduced from 350 kHz to 125 kHz.  
Transmitters can be positioned on adjacent channels with unsubstantial  
intermodulation distortion (IMD).  
In Frequency Diversity mode, the signals from two transmitters from a  
common audio source are routed to the outputs of 2 receiver channels. In  
the event of interference or power loss, the audio from the good channel is  
switched to both outputs to preserve the audio signal. Switching between  
channels is seamless and inaudible.  
High Density mode is ideal for applications where many channels are  
needed in a confined area, transmission distances are short, and the  
number of available frequencies is limited. Up to 30 meters of range is  
available in High Density mode.  
When the receiver senses that the signal quality has improved, audio  
routing is restored without interrupting the audio signal.  
Setting the Receiver to High Density Mode  
To set the receiver to High Density mode:  
Note: WWB6 software offers an option to selectively lock the diversity audio  
source to a specific transmitter (see Wireless Workbench 6 section).  
DEVICE UTILITIES > ADVANCED RF > HIGH DENSITY  
Use the control wheel to set HIGH DENSITY to ON.  
Best Practices for Frequency Diversity  
• Use the same microphone type and model for each transmitter  
• Place microphones within close proximity to the source  
When prompted, sync the transmitter and receiver to enable HIGH DENSITY  
mode.  
• Use the gain controls to match the output levels for each receiver channel  
Note: When the receiver is in HIGH DENSITY mode, the following indicators  
are shown on the receiver display:  
• If Audio Summing is active, use a Y-cable (Shure AXT652) to connect the  
bodypacks to a single audio source to prevent comb filtering  
• The HD icon will appear on the receiver display  
Choosing Diversity Output Routing  
• The receiver band name will be shown with an "HD" added. (example:  
The following receiver channel routing output options are available:  
The G50 band will appear as G50HD)  
• The transmitter group and channel are assigned letters instead of  
numbers (example: G:AA CH:AA)  
• 1 + 2  
• 3 + 4 (quad only)  
• 1 + 2 / 3 + 4 (quad only)  
Best Practices for High Density Mode  
• When band planning, position ULX-D High Density channels in a range of  
To enable Frequency Diversity and select a routing option:  
DEVICE UTILITIES > FREQ DIVERSITY  
frequencies separated from other devices.  
Use the control wheel to choose a routing option, and then press ENTER.  
• Use a separate RF zone for ULX-D High Density channels to prevent  
intermodulation distortion from other devices.  
Note: Choose OFF to disable Frequency Diversity.  
• During High Density channel scanning, turn on all other transmitters and  
move them to their intended position.  
Frequency Diversity and Encryption  
• Perform a walk test to verify transmitter range  
Enabling Encryption while in Frequency Diversity mode provides an  
additional layer of protection by only passing audio from the most recently  
synced encrypted transmitter for each receiver channel.  
• If using custom groups, the groups loaded into the receiver must be  
compatible with High Density mode  
Audio Summing  
Audio summing allows the dual and quad receivers to function as a 2 or 4 channel mixer, respectively. All XLR outputs of the selected channels provide the  
summed audio. For example, when 1 + 2 is selected (see diagram), the XLR outputs of channels 1 and 2 supply the summed audio of the two channels.  
Choosing an Audio Summing Mode  
The following Audio Summing mode options are available:

Firmware  
Firmware is embedded software in each component that controls functionality. Periodically, new versions of firmware are developed to incorporate additional  
features and enhancements. To take advantage of design improvements, new versions of the firmware can be uploaded and installed using the Firmware  
Update Manager tool available in Shure's Wireless Workbench® 6 (WWB6) software. Software is available for download from http://www.shure.com/wwb.  
Firmware Versioning  
When updating receiver firmware, update transmitters to the same firmware version to ensure consistent operation.  
The firmware of all ULX-D devices has the form of MAJOR.MINOR.PATCH (e.g., 1.2.14). At a minimum, all ULX-D devices on the network (including  
transmitters), must have the same MAJOR and MINOR firmware version numbers (e.g., 1.2.x).  
Updating the Receiver  
CAUTION! Ensure that receiver power and network connections are maintained during a firmware update. Do not turn off the receiver until the update is  
complete.  
Once the download is complete, the receiver automatically begins the firmware update, which overwrites the existing firmware.  
1. From Shure Wireless Workbench software, open the Firmware Update Manager: Tools > Firmware Update Manager.  
2. Click Check Now to view new versions available for download.  
3. Select the updates and click download.  
4. Connect the receiver and computer to the same network.  
5. Download the latest firmware to the receiver.  
Updating the Transmitter  
1. To upload the firmware to the transmitter, go to DEVICE UTILITIES > TX FW UPDATE on the receiver.  
2. Place the transmitter on its side and align the IR ports.  
3. Press ENTER on the receiver to begin the download to the transmitter. IR ports must be aligned for the entire download, which can take 50 seconds or  
longer.

from the antennas with 1 additional receiver.  
Encryption  
Use a shielded coaxial cable to connect the RF cascade ports from the first  
receiver to the antenna inputs of the second receiver.  
ULX-D features Advanced Encryption Standard (AES-256) to ensure that  
only the receiver that is keyed to the transmitter can monitor the audio  
content.  
Important! The frequency band must be the same for both receivers.  
Note: When enabled, encryption is applied to all receiver channels.  
Encryption does not affect Dante audio signals, audio quality, or channel  
spacing.

Networking ULX-D Receivers  
ULX-D Dual and Quad receivers feature a Dante dual-port network interface. Dante technology provides an integrated solution to distribute digital audio,  
manage control signals, and carry Shure Control (WWB and AMX/Crestron) signals. Dante uses standard IP over Ethernet and safely coexists on the same  
network as IT and control data. Selectable Dante networking modes route port signals for flexible network set up.  
Network Control Software  
The ULX-D receivers can be controlled by Shure Control (WWB6) for remote management and monitoring and the Dante Controller to manage digital audio  
routing. Signals for AMX and Crestron controllers are carried on the same network as Shure Control.  
Shure Control  
Dante  
Wireless Workbench 6 (WWB6) software provides comprehensive  
control for wireless audio systems. Wireless Workbench enables live  
remote adjustments to networked receivers for real-time changes to gain,  
frequency, RF power, and control locks. A familiar channel strip interface  
displays audio meters, transmitter parameters, frequency settings and  
network status.  
The Dante controller is a free software program created by Audinate™  
to configure and manage a network of Dante enabled devices. Use the  
controller to create audio routes between networked components and to  
monitor the status of online devices.  
Visit www.audinate.com for download and installation instructions.  
Wireless Workbench 6 is available for Windows or Mac and can be  
downloaded at: www.shure.com/wwb  
IP Address Configuration  
An IP address must be assigned to each device in the network to ensure communication and control between components. Valid IP addresses can assigned  
automatically using a DHCP server or manually from a list of valid IP addresses. If using Dante audio, a separate Dante IP address must also be assigned to  
the receiver.  
Automatic IP Addressing  
Manual IP Addressing  
1. If using a DHCP capable Ethernet switch, set the DHCP switch to ON.

Assigning Network Device IDs for Shure Control and Dante Control  
When using the receiver in a network with Shure Control (WWB6) and a Dante Controller, two Device IDs are required: one for Shure Control and one for  
Dante Control. Device IDs are used to identify devices on the network and for creating Dante digital audio routes.  
Best Practices  
Using the following best practices will help to organize network setup and ease troubleshooting.  
• For consistency, convenience, and easy troubleshooting, use the same device ID for both WWB6 (Shure Control) and for the Dante network.  
• The Dante network requires unique Dante device IDs to prevent a loss of audio signal routing. Any duplicate IDs on the network will be tagged with a  
number such as -1, -2, -3, etc.... and must be changed to a unique value.  
• WWB6 (Shure Control) does not require unique device IDs and duplicates do not affect the Dante network; however, a best practice is to use unique  
device IDs.  
Viewing Dante Device IDs in the Dante Controller  
Setting the Shure Control Device ID  
Dante device IDs are displayed in the Network View window in the Dante  
Controller.  
1. Launch WWB6.  
2. Open the Inventory  
View.  
1. Launch the Dante controller and open the Network View window.  
2. Verify that the Dante device IDs match the IDs entered in the receiver.  
3. Click on the Device ID  
to enable editing.  
Tip: Click on the device  
icon next to the channel  
name to identify the  
receiver using the Flash  
function.  
Optionally, the Shure Control Device ID can be entered from the receiver  
front panel:  
1. From the receiver menu: DEVICE UTILITIES > NETWORK > SHURE  
CONTROL > Dev. ID  
2. Use the control wheel to edit the ID.  
3. Press ENTER to save.  
Setting the Dante Device ID  
The Dante ID can be set from the ULXD receiver menu or from the Dante  
controller.  
Note: Changing the Dante ID will cause a loss of audio signal. After an  
ID has been changed, use the Dante controller to restore audio route  
subscriptions using the new ID.  
Identify Device Feature  
From the receiver menu:  
The Dante controller's Identify Device feature flashes the front panel LEDs  
of a selected receiver to provide identification when multiple receivers are  
in use.  
DANTE DEVICE ID  
ULXD-RX1

Configuring Audio Routes with the Dante Controller  
Devices that appear in the Dante controller are categorized as "Transmitters" and "Receivers"  
In order for audio to flow in the network, audio routes (subscriptions) must be configured between transmitters and receivers.  
Note: ULX-D receivers will appear in the Dante controller as a Transmitter. Devices that have both inputs and outputs commonly appear as both transmitters  
and receivers.  
Dante Transmitters

Connecting to an AMX or Crestron System  
The ULX-D receiver connects to an AMX or Crestron control system via the Ethernet, using on the same cables used to carry Shure Control (WWB6). Use  
only one controller per system to avoid messaging conflicts.  
• Connection: Ethernet (TCP/IP; ULX-D receiver is the client)  
• Port: 2202  
For a comprehensive list of ULX-D command strings, visit: http://shure.custhelp.com/app/answers/detail/a_id/4976  
Network Troubleshooting  
• Use only one DHCP server per network  
• All devices must share the same subnet mask  
• All receivers must have the same level of firmware revision installed  
• Look for the illuminated network icon on the front panel of each device:  
If the icon is not illuminated, check the cable connection and the LEDs on the network jack.  
If the LEDs are not on and the cable is plugged in, replace the cable and recheck the LEDs and network icon.  
To check connectivity of WWB6 to the network:  
1. Start WWB6 software and use Inventory view to see devices connected to the network.  
2. If not, find the IP address from one of the devices on the network (such as a ULX-D receiver) and see if you can ping it from the computer running WWB6.  
3. From a WINDOWS/MAC command prompt, type ‘ping IPADDRESS’ of the device (e.g. "ping 192.168.1.100").  
4. If the ping returns success (no packet loss), then the computer can see the device on the network. If the ping returns failure (100% packet loss), then check  
the IP address of the computer to ensure it’s on the same subnet.  
5. If the pings are successful and the devices still do not show up in the WWB6 inventory, check to ensure all firewalls are either disabled or allow the WWB  
network traffic to pass to the application. Check that firewall settings are not blocking network access.

Power  
• Perform a group or channel scan to find the best open frequency.  
Perform a sync to transfer the setting to the transmitter.  
Make sure that the receiver and transmitter are receiving sufficient voltage.  
Check the battery indicators and replace the transmitter batteries if  
necessary.  
• For multiple systems, check that all systems are set to channels in the  
same group (systems in different bands do not need to be set to the  
same group).  
Gain  
• Maintain a line of sight between transmitter and receiver antennas.  
Adjust the system gain on the front of the receiver. Ensure the output level  
(XLR output only) on the back of the receiver corresponds to the input of the  
mixing console, amplifier, or DSP.  
• Move receiver antennas away from metal objects or other sources of  
RF interference (such as CD players, computers, digital effects, network  
switches, network cables and Personal Stereo Monitor (PSM) wireless  
systems).  
Cables  
• Eliminate RF overload (see below).  
Check that all cables and connectors are working correctly.  
Increasing Range  
If the transmitter is more than 6 to 60 m (20 to 200 ft) from the receiver  
antenna, you may be able to increase range by doing one of the following:  
Interface Locks  
The transmitter and the receiver can be locked to prevent accidental or  
unauthorized changes. A locked feature or button will produce the Locked  
screen on the LCD panel.  
• Reduce interference (see above).  
• Increase transmitter RF power level.  
• Use Normal mode instead of High Density mode.  
Encryption Mismatch  
Re-sync all receivers and transmitters after enabling or disabling encryption.  
• Use an active directional antenna, antenna distribution system, or other  
antenna accessory to increase RF range.  
Eliminating RF Overload  
If you see the red RF LED on a receiver, try the following:  
Firmware Mismatch  
Paired transmitters and receivers must have the same firmware version  
installed to ensure consistent operation. See Firmware topic for firmware  
update procedure.  
• Reduce the transmitter RF power level  
• Move the transmitter further away from the receiver—at least 6 m (20 ft)  
• If you are using active antennas, reduce antenna or amplifier gain.  
• Use omnidirectional antennas  
Radio Frequency (RF)  
Antenna Faults  
RF LEDs  
The Antenna Fault message indicates a short circuit condition at an antenna  
If neither blue RF Diversity LED is illuminated, then the receiver is not  
detecting the presence of a transmitter.  
port.  
• Check antennas and cables for damage  
The amber RF Signal Strength LEDs indicate the amount of RF power being  
received. This signal could be from the transmitter, or it could be from an  
interfering source, such as a television broadcast. If more than one or  
two of the amber RF LEDs are still illuminated while the transmitter is off,  
then that channel has too much interference, and you should try a different  
channel.  
• Ensure that antenna ports are not overloaded  
• Check antenna bias voltage setting. Turn off voltage if using passive  
antennas.  
The red RF LED indicates RF overload. This will usually not cause a  
problem unless you are using more than one system at the same time, in  
which case, it can cause interference in the other system.  
Compatibility  
• Perform a Scan and Sync to ensure the transmitter and receiver are set  
to the same group and channel.  
• Look at the label on the transmitter and receiver to make sure they are in  
the same band (G50, J50, L50, etc...).
