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.
