SHURE ULX-D / SM58 Digital Wireless Receiver

Shure Professional-Grade Digital Wireless Audio Quality

  • 24-bit/48 kHz digital audio delivers clear and accurate sound reproduction
  • Extended 20 Hz to 20 kHz frequency range with flat response
  • > 120 dB wide dynamic range for excellent signal-to-noise performance
  • Up to 60 dB of independently adjustable gain for each channel
  • Works with a wide selection of Shure mics and transmitter types including the ULXD1 bodypack and ULXD2 handheld transmitters that provide complete mobility for presenters/performers, and the ULXD6 boundary and ULXD8 gooseneck base transmitters to accommodate meeting rooms with flexible seating layouts 
  • ULX-D receivers are also compatible with QLX-D bodypack and handheld transmitters

Up to 60 Channels with Rock-Solid Transmission

  • Single-channel receiver operates in the H50: 534 to 598 MHz UHF band
  • 64 MHz tuning range lets you run up to 60 channels at the same location in Standard mode or 90 channels in High-Density mode
  • Digital Predictive Switching Diversity uses a microprocessor to switch antennas before dropouts occur
  • Comes with two remoteable 1/2 wave dipole antennas
  • 256-bit AES encryption offers unbreachable privacy—uses unique, randomized encryption key generated every time encryption is enabled
  • Interference detection and alerts provide instant confirmation on both the receiver LCD and WWB software when interference is present
  • Adding UA874 active antennas or PA805 passive antennas increases the range of your system and offers increased protection against interference
  • The UA844+SWB antenna distribution system (available separately) lets you stretch the power of your antenna pairs, giving you more on-air channels in less setup time

Intelligent Hardware Simplifies Setup, Monitoring & Control

Networked Control

  • Ethernet networking enables real-time, precision monitoring and control of your system, as well as automatic frequency coordination across multiple receivers, using Wireless Workbench, SystemOn, and Axient Spectrum Manager software
  • Compatible with external controllers such as AMX and Creston
  • Crosssubnet control-enabled for management between multiple facilities or venues

Functionality

  • Optimized scanning automatically finds, prioritizes, and deploys the cleanest frequencies to transmitters over IR sync
  • Proprietary Gain Ranging optimizes system dynamic range for any input source, eliminating the need for transmitter gain adjustments
  • Internal limiter automatically engages to prevent digital clipping of your audio
  • Unit has an individual gain control, an XLR output with switchable mic/line level, and a 1/4 output 
  • Quick visual check using audio and RF LED meters with peak indicators
  • Intuitive front-panel controls with lockout feature and easily readable LCD with adjustable contrast
  • Remote Control: Make adjustments anywhere in the venue via the Channels Mobile App for iOS devices
  • Smart Power Management on Transmitters: Advanced SB900A lithium-ion rechargeable batteries with SBC chargers (both available separately) provide 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
