Shure ULXD4Q-J50A Quad-Channel Digital Wireless Receiver, J50A Band

The ULXD4Q Quad Channel Digital Wireless Receiver from Shure provides 4 channels of uncompromising audio quality, advanced setup features, and RF signal stability, in a space-efficient single rack unit. Rugged yet compact and lightweight, it has a 1U all-metal chassis that houses four (4) discrete receivers, each including its own audio and RF meters, as well as gain control, plus XLR outputs that can either be either summed or direct to enable flexible signal routing. This particular model utilizes the J50A frequency band.

It's only 7.6 pounds so it offers not only cost-savings when shipping, but space-savings in the rack. With features including RF cascade and two (2) Ethernet ports, multiple units can easily share RF signal and be networked together for much simpler frequency coordination and deployment. For networked audio applications, its onboard Dante™ digital networking delivers multiple channels of audio over a single Ethernet cable.

Complete with the suite of features and benefits that the ULX-D® Digital Wireless Systems offer, the ULXD4Q is truly generations ahead of other available receivers in its class, and brings forth a new level of performance and scale to professional sound reinforcement.

Note: When purchasing separate wireless components, please match their frequency bands to ensure proper system operation.

Features

• Four receivers in a rugged 1U metal chassis with internal power supply
• Individual gain controls, LED meters, and XLR outputs for each channel
