Description
The Shure ULXD4D Dual-Channel Digital Wireless Receiver delivers enterprise-grade wireless audio performance for demanding professional environments. Designed for large venues, corporate AV installations, and mission-critical sound reinforcement, this rackmount receiver provides two independent digital channels with exceptional RF stability and pristine audio clarity.
Operating within the H50 frequency band (534–598 MHz), the ULXD4D features a wide 64 MHz tuning range and supports scalable deployments of up to 60 channels. Advanced Digital Predictive Switching Diversity ensures uninterrupted signal integrity, while AES-256 encryption secures transmissions for confidential applications.
With built-in Dante networking, dual Ethernet ports, and RF cascade connectivity, the ULXD4D integrates seamlessly into modern networked audio infrastructures. Its intuitive interface, real-time monitoring, and flexible gain control make system setup and management efficient, even in complex multi-channel environments.
