Shure QLXD4 Digital Wireless Receiver — V50 (174–216 MHz)
QLXD4 Overview
The Shure QLXD4 is a half-rack digital wireless receiver operating in the V50 band (174–216 MHz), engineered for professional live sound, houses of worship, broadcast, and installed audio environments. It delivers AES 256 encryption for secure RF transmission, digital predictive switching diversity for reliable signal integrity, and an Automatic Channel Scan that rapidly identifies clean frequencies in congested RF environments. The QLXD4 is well suited for audio engineers, system integrators, and venue operators who require dependable wireless performance with minimal setup time.
The one-touch sync function deploys open frequencies directly to transmitters, streamlining deployment in multi-channel configurations. Networked Channel Scan further supports coordinated frequency management across larger systems.
