Shure ULX-D™ Digital Wireless offers uncompromising audio clarity and extremely efficient RF performance with rugged, intelligent, encryption-enabled hardware. Advanced rechargeability options eliminate the need for disposable batteries while extending usage times and life cycle.
Generations ahead of any other available system in its class, ULX-D Digital brings a new level of performance to professional sound reinforcement.
Includes ULXD4 Receiver, ULXD1 Bodypack Transmitter, Handheld Microphone Transmitter, and Lavalier Microphone.
Uncompromising Professional Digital Wireless
- 24-Bit / 48 kHz digital audio delivers incredibly clear and accurate reproduction of the source material
- Wide frequency range with flat response for superb low range and transient response
- Greater than 120 dB dynamic range provides excellent signal-to-noise performance
- Encryption-enabled for any application for which secure transmission is needed
- Advanced Encryption Standard (AES-256) conforming to the US Government National Institute of Standards and Technology (NIST) publication FIPS-197
- Enabled via front panel menu on the receiver and sent over IR sync
- A new, unique, randomized encryption key is generated every time encryption is enabled
- Wide selection of trusted Shure Microphones, including the legendary SM58®
Extremely Efficient and Reliable RF Performance
- Up to 64 MHz overall tuning range (region dependent)
- Up to 14 active transmitters in one 6 MHz TV channel (17 on an 8 MHz TV channel)
- Over 60 compatible channels on one frequency band
- Rock-solid signal stability with no audio artifacts extends over the entire 100 meter line-of-sight range using standard supplied dipole antennas
Rugged, Intelligent Hardware
- Optimized scanning automatically finds and deploys the cleanest frequencies available
- Proprietary Shure Gain Ranging optimizes the system’s dynamic range for any input source, eliminating the need for transmitter gain adjustments
- Up to 60 dB of adjustable system gain is easily accessible from the receiver front panel
- Upgraded LCD screens with adjustable contrast and brightness on both transmitters and receivers
- Rugged metal housing on both transmitters and receiver
- Interference detection and alerts provide instant confirmation when interference is present
- Ethernet networking for streamlined setup across multiple receivers, Wireless Workbench® 6 integration, and AMX/Crestron control
- Support for frequency coordination with the Axient® Spectrum Manager
Advanced Rechargeability – SB900 Shure Rechargeable Battery
- Adapted from industry-leading Axient intelligent power management technology
- Lithium-Ion chemistry and intelligent Shure battery circuitry results in rechargeable batteries with zero memory effect. The battery can be recharged at any time; a complete discharge is never necessary
- Provides ULX-D transmitters with unmatched 12+ hours of performance time
- Transmitters and receivers display remaining battery life in hours and minutes accurate to within 15 minutes
- SBC200 Dual Docking Charger recharges batteries while inside or outside transmitters
- Up to four SBC200s can be linked together to provide docked charging of eight transmitters from one power supply
- The SBC800 Eight-Bay Charger brings up to eight SB900 batteries to full charge within three hours and 50% charge in one hour, with charge status LEDs for each battery
- AA alkaline backwards compatibility
- Both chargers fit in a standard-size rack drawer for easy transport and storage
