General Description
Shure ULX-D™ Digital Wireless offers uncompromising audio quality and
RF performance, with intelligent, encryption-enabled hardware, flexible re-
ceiver 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 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 dy-
namic range for any input source, eliminating the need for transmitter gain
adjustments.
In RF performance, ULX-D sets the bar for spectral efficiency and signal sta-
bility. The intermodulation performance of ULX-D is an incredible advance-
ment in wireless performance, enabling a dramatic increase in the number
of simultaneous active transmitters on one TV channel. 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 trans-
mission is required, ULX-D offers Advanced Encryption Standard (AES) 256-
bit encrypted signal for unbreachable privacy.
Encryption
ULXD features Advanced Encryption Standard (AES-256) encryption,
conforming to the US Government National Institute of Standards and
Technology (NIST) publication FIPS-197.

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 functionality, but differ in the num-
ber 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.

For scalability and modular flexibility, ULX-D receivers come in dual and
quad channel versions providing rack-ready conveniences such as RF cas-
cade, internal power supply, audio output channel summing, and DANTE™
digital networking, which delivers multi-channel audio over Ethernet. All
receivers offer High-Density mode for closer-range 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 accu-
rate to within 15 minutes, and detailed tracking of battery health status.
Combined with the suite of features and benefits ULX-D™ Digital Wireless
Systems offer, the ULXD4D and ULXD4Q receivers are truly generations
ahead of any other digital receivers in their class, and bring a new level of
performance to professional sound reinforcement.
Note: Any change to the encryption status on the receiver such as enabling
encryption or requesting a new encryption key, requires a sync to send the
settings to the transmitter. The Encryption Mismatch warning will display on
the receiver LCD panel if they are not on the same setting.
. The
ULXD4Q Quad Receiver
Supports 4 channels of wireless audio.
