General Description

Shure ULX-D Digital Wireless offers uncompromising audio quality and RF performance, with intelligent, encryption-enabled hardware and advanced re-
chargeability 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. Extended 20 Hz – 20 KHz frequency range and totally flat response captures every detail with clarity, presence, and incredibly accurate low-
end and transient response. At greater than 120 dB, ULX-D delivers wide dynamic range for excellent signal-to-noise performance. For added convenience,
proprietary Shure Gain Ranging optimizes the system's dynamic range for any input source, eliminating the need for transmitter gain adjustments.
In RF performance, ULX-D sets the bar for wireless channel efficiency and signal stability. Minimized intermodulation allows more transmitters to operate si-
multaneously over one TV channel than any other system. Rock-solid RF signal with no audio artifacts extends over the entire 100 meter line-of-sight range,
even using standard dipole antennas. For applications where secure transmission is required, ULX-D offers Advanced Encryption Standard (AES) 256-bit
encrypted signal for unbreachable privacy.
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.

aligned to transfer settings from the receiver to the transmitter
② Infrared (IR) Sync Window
Sends IR signal to the transmitter for sync
③ Network Icon
Illuminates when the receiver is connected with other Shure devices on
the network. IP Address must be valid to enable networked control
④ Encryption Icon

⑧ Control Wheel
Push to select menu items for editing, turn to edit a parameter value
⑨ RF Diversity LEDs
Indicate antenna status:
• Blue = normal RF signal between the receiver and transmitter
• Red = interference detected
• Off = No RF connection between the receiver and transmitter
Note: the receiver will not output audio unless one blue LED is illuminated
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 neces-
sary to change the gain on the transmitter (mic offset) to optimize the gain struc-
ture. Any required changes to gain should be made from the receiver.
