Shure ULXD4D Dual-Channel Digital Wireless Receiver

• 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

• 2-channel receiver operates in the X52: 902 to 928 MHz unlicensed UHF band—targeted for use where UHF "TV band" spectrum is limited or congested
• 26 MHz tuning range lets you run up to 12 channels at the same location in Standard mode or 30 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
• Bodypack frequency diversity ensures uninterrupted audio for mission-critical applications using two discrete bodypacks on a single audio source
• 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

• 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
• Cross subnet control-enabled for management between multiple facilities or venues

Networked Audio

• Dante support allows you to seamlessly send uncompressed, multichannel audio over standard IP Ethernet networks with low-latency, sample-accurate synchronization, and automatic device discovery—on the same network as IT and control data

Two RF Cascade Ports

• Allow distribution of RF antena signals to another receiver unit—ports provide DC bias voltage to power active antennas

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
• Each receiver has an individual gain control and an XLR output with switchable mic/line level
• 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
• Yamaha device ID allows simplified channel patching on CL consoles
• Smart Power Management on Transmitters: Advanced SB900A lithium-ion rechargeable batteries with SBC chargers 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
