Shure SLXD4D-J52 Description

Built for professional use, the Shure SLXD4D-J52 provides transparent digital sound with a wide 20 Hz to 20 kHz frequency response and low latency of just 3.2 ms. The system operates in the J52 frequency band (558–602 MHz + 614–616 MHz), staying clear of crowded 2.4 GHz environments, and offering a tuning range of 46 MHz with 1840 selectable frequencies. Its Digital Predictive Switching Diversity ensures seamless, dropout-free audio by intelligently switching antennas before signal degradation occurs. The dual-channel design enables two microphones to be used simultaneously in a single 1U rackmount chassis, making it space-efficient for flight cases or fixed installs. Setup is streamlined with automatic frequency scanning and IR sync, while the intuitive front-panel LCD displays RF and audio meters for both channels. You also get gain adjustment up to 60 dB, XLR mic/line outputs, 1/4" TRS outs, and Ethernet for network coordination across systems. Ideal for medium-scale live sound reinforcement, corporate A/V, and multi-mic installations, the SLXD4D-J52 offers scalable performance, advanced digital transmission, and rugged build quality trusted by professionals.
