Shure ULXD4D Dual Wireless Receiver

The Shure ULXD4D Dual Channel Digital Wireless Receiver offers two channels of uncompromising audio quality, RF signal stability and efficiency, and advanced setup features in a single rack unit. Now featuring wide-tuning frequency bands, offering an expanded range of up to 166 MHz, (region dependent). 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.

• Two receivers in a rugged 1RU metal chassis with internal power supply
