What digital wireless audio quality does it offer?

Shure digital processing enables ULX-D to deliver pure, clear, and accurate reproduction of source material. An extended 20 Hz – 20 KHz frequency range with totally flat response, combined with 24 bit / 48 kHz digital audio, captures every detail with clarity and presence, plus an incredibly accurate low end and transient response. A wide dynamic range of over 120 dB offers excellent signal to noise performance.
Proprietary Shure Gain Ranging optimises the system’s dynamic range for any level of input source, eliminating the need for transmitter gain adjustments.

Which components does the ULX-D comprise?

Receiver options

Ethernet networking allows for streamlined setup across multiple receivers.
- ULXD4 Wireless Receiver: Half rack
- ULXD4D Dual Channel Wireless Receiver: Full rack
- ULXD4Q Quad Channel Wireless Receiver: Full rack
- ULXD4D (Dual) and ULXD4Q (Quad) receivers incorporate an extensive set of additional features:
  - Bodypack Frequency Diversity
  - RF cascade ports
  - Internal power supply
  - Audio output channel summing, to route audio to multiple outputs
  - Dante™ digital networking for multi-channel audio over Ethernet
  - Dual Ethernet ports
  - Bodypack Frequency Diversity safeguards against loss of audio signal, whether caused by RF interference or by power loss in a transmitter, to ensure uninterrupted audio for mission critical applications. The same audio source is sent from two transmitters with different radio frequencies. If problems occur with the reception of one frequency, ULX-D dual and quad receivers continue to provide flawless audio by automatically switching to the clean frequency. Switching between channels occurs in milliseconds, without any perceivable interruption for users.

Transmitter options

ULXD1 Wireless Bodypack Transmitter: The ULXD1 is compatible with a selection of Shure lavalier, headset, and clip-on instrument microphones.
ULXD2 Wireless Handheld Transmitter: To tailor sound for specific purposes, the ULXD2’s microphone cartridge is interchangeable with the full range of Shure dynamic and condenser cartridges, which offer a diverse set of sound characteristics and polar patterns.

Other components

Wireless Workbench 6: The ULX-D is compatible with Wireless Workbench 6 software, for advanced frequency coordination, monitoring, and control.

What third party systems is it compatible with?

The ULX-D offers seamless integration with AMX and Crestron media control systems.

What are the ULX-D’s wireless features?

The ULX-D delivers class leading wireless channel efficiency (region dependent) and signal stability. Minimised intermodulation distortion allows significantly more transmitters to operate simultaneously on each channel.
In standard mode, up to 22 transmitters can operate in an 8 MHz TV channel. However, 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. In High Density mode, up to 63 active transmitters can operate in an 8 MHz TV channel, with no audio quality degradation.
For ease of use, optimised scanning automatically finds, prioritises, and selects the cleanest frequencies available. Interference detection provides instant alerts if the system encounters interference.
For applications where secure transmission is required, ULX-D offers Advanced Encryption Standard (AES) 256 bit encrypted signal for complete privacy. This helps to reduce RF interference by only allowing the encrypted signal through to the receiver.
Advanced lithium ion battery technology provides an extended run time over alkaline batteries, up to 12 hours of continuous use, with detailed tracking of battery health status. Lithium ion chemistry and intelligent Shure battery circuitry results in rechargeable batteries with no memory effect, such that a complete discharge is never necessary to maintain battery health. Transmitters and receivers display remaining battery life in hours and minutes accurate to within 15 minutes.
