Description
The Shure SLXD4Q+ Quad-Channel Digital Wireless Receiver delivers reliable, high-performance wireless audio for professional environments that demand clarity, stability, and scalability. Designed for small- to medium-sized venues, conference spaces, houses of worship, and educational facilities, this all-metal, single-rack receiver provides four channels of pristine 24-bit digital audio in a compact and rugged chassis.
Operating within the G57 frequency band (470–608 MHz), the SLXD4Q+ offers a wide 138 MHz tuning range and 5520 selectable frequencies, ensuring flexible deployment and minimal interference. Digital Predictive Switching Diversity continuously monitors RF signals and seamlessly switches antennas to maintain a clean, uninterrupted connection.
With intuitive front-panel controls, a high-contrast LCD, and built-in RF and audio metering, setup and monitoring are fast and efficient. The receiver supports up to 32 simultaneous microphone channels and features Ethernet networking for centralized control via Shure Wireless Workbench. Dual RJ45 ports allow for easy integration into networked AV systems, while RF cascading enables expansion to larger multi-channel setups.
Flexible audio output options, including XLR and 1/4" TRS outputs per channel, combined with adjustable gain and audio summing capabilities, allow seamless integration with a wide range of mixers and sound systems. Built for both portability and permanent installations, the SLXD4Q+ is a dependable solution for professional wireless audio applications.
