ULXD4Q
Quad-Channel Digital Wireless Receiver
Digital quad wireless receiver offers an intelligent four-channel option for use in any professional sound reinforcement application. Features include Digital Predictive Switching Diversity, 64 MHz tuning range, and AES 256 encryption for security.
Product Details
The Shure ULXD4Q Quad Channel Digital Wireless Receiver offers four channels of uncompromising audio quality, RF signal stability, and advanced setup features in a space-efficient single rack unit. Rugged yet lightweight and compact, the 1RU all-metal chassis houses four independent receivers, each with its own audio and RF meters, gain control, and XLR outputs that can be either direct or summed for flexible signal routing.
At only 7.6 pounds, the ULXD4Q offers space savings in the rack and cost savings when shipping. With RF cascade and two Ethernet ports, units can easily 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 over a single Ethernet cable.
With the suite of features and benefits ULX-D® Digital Wireless Systems offer, the ULXD4Q is truly generations ahead of any other available receiver in its class, and brings 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.
