ULXD4D Dual Receiver ULXD4Q Quad Receiver

ULX-D Digital Wireless Microphone System

General Description

Shure ULX-D™ Digital Wireless offers uncompromising 24-bit audio quality and RF performance, with intelligent, encryption-enabled hardware, flexible receiver options, and advanced rechargeability options for professional sound reinforcement.

A breakthrough in wireless audio quality, Shure digital processing enables ULX-D to deliver the purest reproduction of source material ever available in a wireless system, with a wide selection of trusted Shure microphones to choose from. Extended 20 Hz – 20 kHz frequency range and flat response captures every detail with clarity, presence, and incredibly accurate low end and transient response. With greater than 120 dB, ULX-D delivers wide dynamic range for excellent signal-to-noise performance. Optimized for any input source, ULX-D eliminates the need for transmitter gain adjustments.

ULX-D sets a new and unprecedented standard for spectral efficiency and signal stability. The intermodulation performance of ULX-D is an incredible advancement in wireless performance, enabling a dramatic increase in the number of simultaneous active transmitters on one TV channel. Rock-solid RF signal with zero audio artifacts extends over the entire range. For applications where secure wireless transmission is required, ULX-D offers Advanced Encryption Standard (AES) 256-bit encrypted signal for unbreakable privacy.

For scalability and modular flexibility, ULX-D receivers come in single, dual, and even quad channel versions. The dual and quad channel receivers offer conveniences such as RF cascade, internal power supply, bodypack frequency diversity, audio output channel summing, and Dante™ digital networking for multi-channel audio over Ethernet. All receivers offer High-Density mode for applications where high channel counts are needed, greatly increasing the amount of simultaneous channels possible over one frequency band.

Advanced Lithium-ion rechargeability provides extended transmitter battery life over alkaline batteries, battery life metering in hours and minutes accurate to within 15 minutes, and detailed tracking of battery health status.

Generations ahead of any other available system in its class, ULX-D brings a new level of performance to professional sound reinforcement.

Use this to turn on a transmitter without interfering with the RF spectrum.

Press and hold the exit button during power-on until RF MUTED is displayed. To un-mute, restart the transmitter.

Transmitter Input Clip MIC.OFFSET

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

Tx OVERLOAD

To correct, set MIC.OFFSET to 0 dB and if necessary, attenuate the signal source.

If the source cannot be attenuated while using a bodypack transmitter, select INPUT PAD from the main menu to attenuate the input signal by 12 dB.

MIC.OFFSET compensates for signal level

differences between transmitters that share the same receiver channel.

Set the offset gain on a low signal level transmitter to match a louder transmitter: UTILITY > MIC.OFFSET

Note: For normal gain adjustments, use the receiver gain buttons.

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.

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.

Use this procedure to tune a receiver and transmitter to the best open channel.

Important! Before you begin: Turn off all transmitters for the systems you are setting up. (This prevents

them from interfering with the frequency scan.) Turn on the following potential sources of interference so they are operating

as they would be during the presentation or performance (the scan will detect and avoid any interference they generate).

• Other wireless systems or devices

• Computers

• CD players

• Large LED panels

• Effects processors

1. Press the SEL button to select a channel.

2. Perform a channel scan on the receiver: SCAN > GROUP SCAN.

3. Press SCAN to start the scan. SCANNING appears on the LCD during the scan.

4. After the scan completes, the receiver displays the group with the most available frequencies. Press the flashing ENTER button to deploy frequencies to each receiver channel.

5. Power on the ULXD transmitter.

6. Press the sync button on the receiver.

7. Align the IR windows until the receiver IR port illuminates red.

8. When complete, SYNC SUCCESS! appears. The transmitter and receiver are now tuned to the same frequency.

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.

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.

Networked Receivers

1. Turn on all receivers.

2. Conduct a group scan on the first receiver to find available frequencies in each group: SCAN > GROUP SCAN.

3. Press ENTER to accept the group number and automatically assign the next best channel to each receiver on the network. The receiver LEDs will flash when a frequency has been assigned.

4. Turn on a transmitter and sync to the receiver.

Important! Leave the transmitter on and repeat this step for each additional system.

Non-networked Receivers

1. Turn on all receivers.

2. Conduct a group scan on the first receiver to find available frequencies in each group: SCAN > SCAN > GROUP SCAN > SCAN

3. When the scan is complete, use the control wheel to scroll through each group. Press ENTER to select a group that has enough available frequencies for all channels in the system.

4. Sync a transmitter to each receiver channel.

Important! Leave all transmitters on use the following steps to set up additional receiver channels:

1. Set each additional receiver channel to the same group as the first receiver: RADIO > G:

2. Conduct a channel scan to find available frequencies within the group:

SCAN > SCAN > CHANNEL SCAN > SCAN

3. When the scan is complete, press ENTER to assign frequencies to each receiver channel.

4. Sync a transmitter to each receiver channel.
