Important Tips for Care and Storage of Shure Rechargeable Batteries

Proper care and storage of Shure batteries results in reliable performance and ensures a long lifetime.

• Always store batteries and transmitters at room temperature
• Ideally, batteries should be charged to approximately 40% of capacity for long-term storage
• During storage, check batteries every 6 months and recharge to 40% of capacity as needed

Installing the Battery Contact Cover

Install the included battery contact cover (65A15947) on the handheld transmitter to prevent light reflection in broadcast and performance situations.

1. Align the cover as shown.
2. Slide the cover over the battery contacts until it is flush with the transmitter body.

Note: Slide the cover off before inserting the transmitter in the battery charger.

Receiver Gain Controls

The gain can be adjusted by using the gain ▲▼ buttons or by entering the AUDIO menu and using the control wheel.

Tip: To quickly adjust the gain, press and hold a gain button to enable accelerated scrolling.

Reading the Audio Meter

The audio meter displays yellow, green, and red LEDs to indicate the audio signal level. Audio peaks illuminate the LEDs for 2 seconds, while the RMS signal is displayed in realtime.

When setting up the receiver, adjust the gain so that the average signal LED levels are solid green and occasionally yellow, with only the highest peaks causing the red LED to illuminate.

Tip: If a vocalist is overloading a bodypack transmitter, try lowing the receiver gain. If additional attenuation is needed, use the transmitter menu to set the INPUT PAD to -12dB.

Note: Illumination of the red OL (overload) LED indicates the internal limiter is engaged to prevent digital clipping.

Muting a Receiver Channel Audio Output

The audio output of each receiver channel can be independently muted to prevent audio from passing. Mute status is indicated by Rx MUTED message appearing on the receiver display in place of the gain value.

Note: Receiver gain is disabled for muted channels to prevent unexpected changes in audio levels.

To set a receiver channel output to mute:

1. AUDIO  > MUTE
2. Use the control wheel to select ON or OFF.
3. Press ENTER to save.

To unmute the receiver output:

Simultaneously press the ▲▼ buttons or select OFF from the MUTE menu option.

Tip: Audio mute can be enabled remotely from Wireless Workbench or from an external controller.

Important! A power cycle will reset the receiver and unmute the audio output.

Transmitter Input Clip

The following warning displays on the receiver LCD panel when the transmitter input is clipped:

To correct, select INPUT PAD from the main menu and attenuate the input signal by 12 dB. If the warning persists, reduce the level of input signal.

Audio Summing

Audio summing allows the dual and quad receivers to function as a 2 or 4 channel mixer, respectively. Summed audio is available on all outputs (Dante and XLR). For example, when 1 + 2 is selected (see diagram), the outputs of channels 1 and 2 supply the summed audio of the two channels.

Receiver Output Level

The following table describes the typical total system gain from the audio input to the receiver outputs:

Receiver Output Gain

*This setting matches a typical wired SM58 audio signal level.

Multiple System Setup

A setup using networked receivers is the fastest and easiest way to distribute the best open channel to each system. See Networking ULX-D Receivers for networking details.

Note: Networked receivers must all be within the same frequency band.

Manual Frequency Selection

To manually adjust group, channel, or frequency:

1. Press SEL to choose a receiver channel and navigate to the RADIO menu.
2. Use the control wheel to adjust the group, channel, or frequency.
3. Press ENTER to save changes.

Transmitter RF Power

Reference the following table for setting RF Power:

Note: Using the 20 mW setting decreases the transmitter battery runtime and reduces the number of compatible systems.

Interference Detection

Interference Detection monitors the RF environment for potential sources of interference which can cause audio dropouts.

When interference is identified, the RF LEDs illuminate red and the following warning displays on the receiver LCD panel.

If the warning display persists or the audio drops out repeatedly, perform a Scan and Sync at the first opportunity to find a clear frequency.

High Density Mode

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).

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.

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.

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.

When the receiver senses that the signal quality has improved, audio routing is restored without interrupting the audio signal.

Note: In Wireless Workbench, you can selectively lock the diversity audio source to a specific transmitter. See "Lock or Unlock a Frequency Diversity Channel" in the Wireless Workbench help system for more on this.

Setting Regional TV Format

To ensure accurate display of TV channel information, set the TV FORMAT to match the TV channel bandwidth in the region where the receiver is operating. TV bandwidth varies globally, so check local regulations to determine the regional TV bandwidth.

The following TV FORMAT options are available:

• 6 MHz
• 7 MHz
• 8 MHz
• 6 MHz JAPAN
• NO TV (use to turn off TV channel display or in regions where TV channels are not applicable)

To set the TV FORMAT:

1. Menu: DEVICE UTILITIES > ADVANCED RF > TV FORMAT
2. Use the control wheel to select a TV FORMAT option.
3. Press ENTER to save.

Custom Groups

Use this feature to create and export up to 6 groups of manually selected frequencies to networked receivers prior to a group scan to simplify system set up.

Tip: Use Wireless Workbench or Wireless Frequency Finder to select the best compatible frequencies. See www.shure.com for more information.

To create a custom group: DEVICE UTILITIES > ADVANCED RF > CUSTOM GROUPS > SETUP

Use the control wheel to choose group, channel and frequency values. Press ENTER to save.

Prior to performing a group scan, export a custom group to networked receivers:

1. Go to DEVICE UTILITIES > ADVANCED RF > CUSTOM GROUPS > EXPORT
2. Press the flashing ENTER button to export all custom groups to all receivers on the network.

Note: Use the CLEAR ALL option to remove all custom group settings.

Audio Signal Encryption

When encryption is enabled, the receiver generates a unique encryption key which is shared with a the transmitter during an IR sync. Transmitters and receivers that share an encryption key form a protected audio path, preventing unauthorized access from other receivers.

Note: For some units, encryption is always on and cannot be configured.

RF Cascade Ports

The receiver has 2 RF cascade ports on the rear panel to share the signal from the antennas with 1 additional receiver.

Use a shielded coaxial cable to connect the RF cascade ports from the first receiver to the antenna inputs of the second receiver.

Important! The frequency band must be the same for both receivers.

Antenna Bias

Antenna ports A and B provide a DC bias to power active antennas. Set the DC power to off when using passive (non-powered) antennas.

To turn bias off: DEVICE UTILITIES > ADVANCED RF > ANTENNA BIAS > OFF

Network Control Software

You can remotely manage and monitor your ULX-D receivers using Wireless Workbench and monitor digital audio routing using the Dante Controller. Signals for AMX and Crestron controllers are carried on the same network as Shure Control.

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.

Networking Acronyms

DHCP: Dynamic Host Configuration Protocol

LAN: Local Area Network

MCU: Micro Controller Unit

RJ45: Ethernet connection

RX: Receiver

TX: Transmitter

WWB: Wireless Workbench software

VLAN: Virtual Local Area Network

MAC: Machine Access Code

Overview of Dante Network Modes

The Dante network interface has two ports (Primary and Secondary) to provide flexible routing and configuration options for network signals.

Three selectable Dante network modes are available to control signal routing from the receiver ports to the Dante network.

Network Connection and Configuration Examples

Note: Use shielded Cat5e cable for network connections to ensure reliable performance.

Assigning Network Device IDs for Shure Control and Dante Control

When using the receiver in a network with Shure Control (Wireless Workbench) 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.

Route Audio with Dante Controller

In Dante Controller, devices 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. To learn about creating subscriptions between devices, see the Dante Controller user guide.

Note: ULX-D receivers will appear in Dante Controller as a transmitter. Devices that have both inputs and outputs commonly appear as both transmitters and receivers.

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.

For more information, see Wireless Workbench network troubleshooting.

Restoring Dante Factory Settings

The receiver and the Dante network card can be reset to restore factory Dante settings. Performing a reset is helpful for clearing existing data before setting up a system.

Caution! Performing a reset on either the Dante network card or on the ULX-D receiver will interrupt the Dante audio.

Tip: Prior to performing a factory reset, note the current Dante network mode and IP settings. After a reset, the Dante network mode reverts to SWITCHED, and the IP address mode revert to AUTO.

Firmware Versions

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.

IMPORTANT! Receivers running firmware prior to 1.4.8 must be updated to 1.4.8 before updating to newer versions. Receivers running firmware between 1.4.8 and 2.0.28 must be updated to 2.0.28 before updating to newer versions. See the ULX-D Firmware Update and Issues FAQ for more information on this update procedure.

Once the download is complete, the receiver automatically begins the firmware update, which overwrites the existing firmware.

1. Open the Shure Update Utility.
2. Click the Check for Updates button (for example, 5 Updates Available) to view new firmware versions available to download.
3. Select the updates and click Download. The new downloads are added to the Firmware tab, making them available to install on the device hardware.
4. Connect the receiver and computer to the same network.
5. If your receiver has firmware older than 2.0.28 installed on it, refer to the ULX-D Firmware Update and Issues FAQ for specific instructions.
6. From the Update Devices tab, send the latest firmware to the receiver.

   Once the transfer is complete, the receiver automatically begins the firmware update, which overwrites the existing firmware. For more information on the Shure Update Utility, visit the Shure Update Utility user guide.

Updating the Transmitter

1. Place the transmitter on a microphone or music stand, and roughly align the stand so that the transmitter’s IR window can be aligned with the receiver. Shure does not recommend holding the transmitter during the update.
2. To upload the firmware to the transmitter, go to DEVICE UTILITIES > TX FW UPDATE on the receiver.
3. Align the IR ports.
4. 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.

Setting the Gateway to Allow Cross Subnet Routing

ULX-D receivers include gateway addressing to support cross-subnet routing. The gateway setting allows a single controller to manage devices assigned to different subnets such as multiple rooms or multiple buildings.

Note: A gateway address is an advanced network setting. In most network configurations, the setting does not need to be changed.

To set the receiver gateway:

1. From the receiver menu: DEVICE UTILITIES > NETWORK > SHURE CONTROL > NETWORK
2. Press and turn the control wheel to set the Mode to Manual.
3. Press the control wheel to navigate to the first digit of the GW (gateway) setting.
4. Turn the control wheel to change a value, press the control wheel to advance to the next octet.
5. When finished, press ENTER to save.

Note: When setting the gateway address, the IP address and subnet must be set to valid addresses.

Power

Make sure that the receiver and transmitter are receiving sufficient voltage. Check the battery indicators and replace the transmitter batteries if necessary.

Gain

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.

Cables

Check that all cables and connectors are working correctly.

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.

Encryption Mismatch

Re-sync all receivers and transmitters after enabling or disabling encryption.

Firmware Mismatch

Paired transmitters and receivers must have the same firmware version installed to ensure consistent operation. See the Firmware topic for firmware update procedure.

Tx Battery Hot

If the transmitter battery does not cool off, the transmitter will shut down. Let the device cool down and then consider swapping the transmitter battery to continue operation.

Identify any possible external heat sources to the transmitter and operate the transmitter away from those external heat sources.

All batteries should be stored and operated away from external heat sources in reasonable temperature conditions for best performance.

Radio Frequency (RF)

The Antenna Fault message indicates a short circuit condition at an antenna port.

• Check antennas and cables for damage
• Ensure that antenna ports are not overloaded
• Check antenna bias voltage setting. Turn off voltage if using passive antennas.
