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.
