Quickstart Instructions
General Description
Shure ULX-D Digital Wireless offers uncompromising 24bit audio quality and RF performance, with intelligent, encryptionen
abled 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 perfor
mance. 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 ac
tive transmitters on one TV channel. Rocksolid RF signal with zero audio artifacts extends over the entire range. For applica
tions 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 possi
ble 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.
Dual and Quad Receiver Models
The ULXD4 receiver is available in dual channel and quad channel models. Both models share the same feature set and func
tionality, but differ in the number of channels available and the number of audio outputs.
The descriptions and procedures in this guide are applicable to either the dual or the quad receiver.
ULXD4D Dual Receiver
Supports 2 channels of wireless audio.
ULXD4Q Quad Receiver
Supports 4 channels of wireless audio.

Advanced Transmitter Features
RF MUTE
Use this to turn on a transmitter without interfering with the RF spectrum.
Press and hold exit during power-on until RF MUTED is displayed. To un-mute, restart the transmitter.
MIC.OFFSET
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.
Transmitter Audio Mute Mode
Mute Mode reconfigures the transmitter power switch to act a mute switch for the audio. Using the switch, the audio can be
easily turned on or muted by presenters, sports referees, or anyone who periodically needs to speak. When the audio is muted,
the transmitter RF signal remains on and ready at all times.
Note: Mute Mode can be selected as an IR PRESET option.
To set a transmitter to Mute Mode:
From the transmitter menu: UTILITY > MUTE MODE
Use the arrows to select ON or OFF.
Press enter to save.
Tip: The transmitter LED turns red when audio is muted and turns green when audio is enabled. The display of the transmitter
will show AUDIO MUTED and the receiver display will show Tx Muted.
Note: Mute Mode must be set to OFF in order to use the power switch to turn off the transmitter.
