Wireless Receiver Shure ULXD4QE-K51

The Shure ULXD4Q is a digital wireless receiver that provides an intelligent 4-channel option for use in any professional sound reinforcement system. The rugged yet lightweight and compact all-metal chassis houses independent receivers, each with its own audio and RF meters, gain control, and outputs that can be either direct or summed for flexible signal routing. With an RF cascade and two Ethernet ports, devices can easily exchange RF signal and network for easy coordination and frequency deployment. Audio signal summing allows the receiver to be used as a 4-channel mixer. The receiver is ideal for professional sound reinforcement in large concert venues, as well as in conference rooms, educational and corporate institutions. Compatible with a wide range of transmitters, it delivers pure 24-bit/48kHz digital audio, capturing every detail with clarity, accurate bass reproduction and crisp transient response. ULX-D uses Diversity Digital Predictive Switching to protect transmission from interference, ensuring radio signal stability without audio artifacts. When using more compatible frequencies over short distances, you can enable High-Density mode, which greatly increases the number of open frequencies available.

Note: When purchasing individual wireless components, please check their frequency bands to ensure proper system operation. Shure ULXD4QE-K51 operates in the frequency range 606 - 670 MHz.
