Product Details

Features

RThe Shure ULXD4D Dual Channel Digital Wireless Receiver offers two channels of uncompromising audio quality, RF signal stability and efficiency, and advanced setup features in a single rack unit. Rugged, yet lightweight and compact, the all-metal chassis houses two independent receivers, each with its own audio and RF meters, gain control, and receiver outputs that can be either direct or summed for flexible signal routing.


With RF cascade and two Ethernet ports, units easily can share RF signal and be networked together for simplified frequency coordination and deployment. For networked audio applications, Dante™ digital networking allows multiple channels of audio to be transmitted and received over a single Ethernet cable. When more compatible frequencies over shorter distances, High Density mode can be enabled to dramatically increase the number of available open frequencies.

With the suite of features and benefits ULX-D® Digital Wireless Systems offer, the ULXD4D is truly generations ahead of any other dual digital receiver in its class, and brings a new level of performance to professional sound reinforcement.

Note: When purchasing separate wireless components, please match their frequency bands to ensure proper system operation.

Features

  • Two receivers in a rugged 1RU metal chassis with internal power supply
  • Individual gain controls, LED meters, and XLR outputs for each channel
  • Up to 64 MHz tuning range (region dependent)
  • Digital predictive switching diversity
  • High Density mode optimizes ULX-D systems to simultaneously operate significantly more channels in applications up to 30 meters
  • RF cascade ports allow distribution of RF signal to another unit
  • Optimized scanning automatically finds, prioritizes, and deploys the cleanest frequencies to transmitters over IR sync
  • Bodypack frequency diversity ensures uninterrupted audio for mission-critical applications
  • AES 256-bit encryption-enabled for secure transmission
  • Audio summing routes both audio channels to each XLR receiver output
  • Dante™ digital networked audio over Ethernet
  • Up to 60 dB independently adjustable gain for each channel
  • Ethernet networking for streamlined frequency coordination and deployment across multiple receivers
  • Wireless Workbench® 6 (WWB6) software integration for advanced coordination, monitoring, and control
  • AMX/Crestron® control
  • AXT600 Axient® Spectrum Manager compatible
  • Yamaha® device ID allows simplified channel patching on CL consoles
  • Intuitive front panel LCD menu and controls with lockout feature
  • Audio and RF LED meters with peak indicator
  • XLR connectors with switchable mic/line output level
  • Remoteable ½ wave antennas

ULXD4D - Dual Channel Digital Wireless Receiver (1.4.14) See release notes

Posted January 30, 2014

NEW FEATURES

  • Optional Encryption Enhancement
    • On (Auto): Functions the same as all previous versions of ULX-D where there is a new key generated on each sync.
    • On (Manual): New function to support multiple transmitters; useful for situations such as a combo system that needs to be encrypted and have two transmitters ready to use with one receiver.
      • On (Manual): Issues the same key on every sync so you can easily have multiple transmitters (handheld and/or bodypack) synced and ready to use with one receiver.
      • Regenerate Keys: This allows the user of manual mode to ask the receiver to create a new 256 bit encryption key.  Note that it is required to sync transmitters to ge the new key.

IMPROVEMENTS

  • TV Display format is restored as a part of system reset to factory default, and can be saved/recalled as a preset.
  • Group Scan now auto-deploys all custom groups to units within the same frequency band along with the frequency information previously shared
  • Completed all Third-Party Control reporting for all features that can be reported via that < GET x ALL > command.
  • Dante network configurations changes become functional right away via an auto system reboot.

NOTES

  • For operation of ULX-D devices with other Shure networked systems, see the following list of minimum firmware versions that are supported with ULX-D version 1.4.14:

ULXD4D - Dual Channel Digital Wireless Receiver (1.4.8) See release notes

Posted December 09, 2013

NEW FEATURES

  • Support of Multiple Simultaneous Third Party Controllers
    • ULX-D now supports for multiple (up to 5) simultaneous of Third Party controllers such as AMX and Crestron.  This allows programmers to issue independent commands from any Third Party controller on the network and each other Third Party controller on the network will be provided the response from ULX-D
  • TV Channel Format is User Selectable
    • The TV channel reported on ULX-D can be adjusted depending upon regional needs so a particular frequency will display as the appropriate TV channel.
  • Custom Group Deploy
    • ULX-D recievers automatically deploy all Custom Groups to recievers within the same frequency band when the user accepts the results of the group scan.

IMPROVEMENTS

  • Additional Third Party Control Strings
    • The following strings enable quicker changeovers  via networked control instead of manual adjustment on each reciever:
      • High Density: ON/OFF
      • Encryption: ON/OFF
      • Frequency Diversity: OFF, 1+2
      • Audio Summing: OFF, 1+2
  • Frequency Diversity Enhancement
    • ULX-D prioritizes the results of a scan such that the two frequencies of a frequncy diversity system are more likely to be spread further appart instead of right next to each other.  Note that this is RF environment dependant.

NOTES

  • For operation of ULX-D devices with other Shure networked systems, see the following list of minimum firmware versions that are supported with ULX-D version 1.4.8:
    • ULXD1/2 ULXD Transmitters 1.4.8

ULXD4D - Dual Channel Digital Wireless Receiver (1.3.6) See release notes

Posted July 03, 2013

NEW FEATURES

  • Addition of Dante Device ID modes
    • ID Mode: Sequential - Quick sequential numbering of ULX-D receivers to take advantage of quick device set-up and labeling for Dante digital audio network.
    • ID Mode: Yamaha - specific labeling of ULX-D receiver's Dante Device ID for discovery as "online devices" by Yamaha CL Series consoles with firmware version 1.60 or later.
  • Receiver Mute
    • Previously, receiver channels could be muted from Wireless Workbench amd not on device.  Mute on/off capability has been added to the device within the AUDIO menu.  Receiver mute for a channel can also be disengaged via a two-button combination push of the up/down gain arrows of that channel.
    • When "Rx Mute" has been engaged, the ability to adjust system gain is disabled.  Receiver channels must be unmuted in order to adjust system gain.
    • Muting of a receiver channel is non-persistent (i.e. all channels with "Rx Mute" engaged will no longer be muted after the device is power-cycled).
  • Device Gateway Address
    • ULX-D receiver's gateway address can now be set to allow for cross-subnet control and monitoring of the receiver with 3rd party control surfaces.
    • NOTE: Wireless Workbench does not function across different subnets.  This feature is for 3rd party control surfaces only.
  • Hardware Identification in Wireless Workbench
    • Enables the user to trigger a flashing sequence from the physical device to locate the Wireless Workbench representation of that device in the software.

IMPROVEMENTS

  • Added support for the X51 frequency band for use in Korea
  • Minor UI text changes for consistency across wireless lines and in Wireless Workbench.

    1. Using the Shure Update Utility, downgrade the firmware for the ULXD4/ULXD4D/ULXD4Q Receiver to 1.5.6 AND keep the desired transmitter firmware (1.6.7 or latest version).
    2. Update the transmitter firmware to 1.6.7 or the latest version via IR menu. From the receiver menu: DEVICE UTILITIES > TX FW UPDATE. Align the infrared ports with the transmitter and then press ENTER.
    3. Upgrade receiver to 1.6.7 or latest version.
