Quickstart Instructions

Shure Incorporated

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.

Shure Incorporated

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.

ULXD4D and ULXD4Q Receivers

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.
