The U-D4D Dual Channel Digital Wireless Receiver provides two channels of high-quality audio, RF signal stability, and efficiency, along with advanced setup features. The rugged yet lightweight and compact design features an all-metal chassis that accommodates two independent receivers. Each receiver includes its own audio and RF meters, gain control, and receiver outputs that can be used for direct or summed signal routing, offering flexibility.

With an RF cascade and two Ethernet ports, units can easily share RF signals 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 are needed over shorter distances, High-Density mode can be enabled to dramatically increase the number of available open frequencies.

The U-D4D integrates a series of functions and advantages of an excellent digital wireless system. It is truly generations ahead of any other dual digital receiver in its class and brings a new level of performance to professional sound reinforcement.


FEATURE

• Two receivers in a rugged 1RU metal chassis with internal power supply
• Individual gain controls, LED meters, and XLR outputs for each channel
• Digital predictive switching diversity
• 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
• Audio summing routes both audio channels to each XLR receiver output
• Up to 60 dB independently adjustable gain for each channel
• 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
• Long Working Range 100 m(Actual range depends on RF signal absorption, reflection and interference.)
• Optional handheld microphone:①M-58（Dynamic ; default allocation）, ② B-58A(Dynamic/Condenser)，③KM9(Dynamic)
