ULX-D^®

Uncompromising Digital Wireless Audio

• 24-bit/48 kHz digital audio that delivers incredibly clear and accurate reproduction of the source material
• 20 Hz – 20 kHz frequency range with flat response
• Greater than 120 dB dynamic range through the analog outputs
• 130 dB dynamic range (typical) using Dante and AES67 digital networked audio
• 60 dB of adjustable system gain easily accessible from the receiver front panel
• No transmitter gain adjustments needed: optimised for any input source
• Wide selection of trusted Shure Microphones

Extremely Efficient and Reliable RF Performance

• Expanded tuning range - ULXD1, ULX2, ULXD4D and ULXD4Q components now available with up to 166 MHz overall tuning range (region dependent)*
• Up to 17 active transmitters in one 6 MHz TV channel (23 on an 8 MHz TV channel)
• High Density mode enables up to 47 active transmitters in one 6 MHz TV channel (63 in one 8 MHz TV channel), with no audio quality degradation
• Rock-solid signal stability with no audio artifacts over the entire 100 meter line-of-sight range using standard supplied ½ wave antennas
• Selectable 1, 10, and 20 mW transmitter RF output power (comparable to 5 times the analog RF output power equivalent)
• For ease of use, optimised scanning automatically finds, prioritises, and selects the cleanest frequencies available.

*Note that ULXD4, ULXD6 and ULXD8 remain available for operation on legacy frequency bands

Scalable, Intelligent Hardware

• Single (half-rack), Dual, and Quad (full-rack) receiver form factors for any size installation
• AES-256 bit encryption equipped for secure wireless transmission
• Ethernet networking allows for streamlined setup across multiple receivers.
• Wireless Workbench 6: The ULX-D is compatible with Wireless Workbench 6 software for advanced frequency coordination, monitoring, and control.
• Comprehensive 3rd party control and monitoring across subnets
• AXT600 Axient® Spectrum Manager compatibility
• Rugged metal housing on both transmitters and receiver
• Dual and Quad receivers additionally feature:
  • Expanded tuning range (up to 166 MHz, region dependent)
  • RF cascade ports, internal power supply, and dual Ethernet ports
  • Dante™ digital networked audio over Ethernet 
  • Bodypack frequency diversity ensures uninterrupted audio for mission-critical applications 
  • Audio summing routes audio signal to multiple outputs

Shure Advanced Power Management

• SB900 Series rechargeable batteries provides ULX-D transmitters with up to 12 hours of run-time use
• Lithium-Ion chemistry and intelligent Shure battery circuitry for precision metering and zero memory effect saving the equivalent of 1000 disposable batteries
• Transmitters and receivers display remaining battery life in hours and minutes, accurate to within 15 minutes.
• AA backwards compatibility
