Shure GLXD24R+/SM58 Z4 – Dual-band rackmount wireless system with SM58® handheld microphone
The Shure GLXD24R+/SM58 Z4 is part of the new generation of GLX-D+ wireless systems, officially replacing the GLX-D and GLX-D Advanced lines, while bringing essential improvements such as a wider spectrum range, enhanced RF performance, extended battery life, and reinforced reliability.
Thanks to its dual-band wireless technology, the GLX-D+ operates simultaneously in 2.4 GHz and 5.8 GHz, more than doubling the available bandwidth and avoiding interference for a clean, stable, dropout-free transmission. Ideal for musicians, presenters, speakers, and professionals seeking a hassle-free wireless solution.
The system is built around the legendary SM58® microphone, the world standard for vocal performance. Its handheld transmitter GLXD2+ features an interchangeable cardioid dynamic capsule, delivering a natural, warm sound with excellent feedback rejection.
The rackmount receiver GLXD4R+ Z4 ensures automatic frequency management, optimized antenna distribution, and fast, seamless synchronization with the transmitter. It supports up to 11 simultaneous systems under normal conditions, and up to 16 when used with the optional GLX-D+FM frequency manager.
For power, the SB904 lithium-ion rechargeable battery provides up to 12 hours of continuous runtime and benefits from intelligent charging options (via USB-C, the receiver, or an external charger).
The GLXD24R+/SM58 comes fully equipped and ready to use, including the handheld mic, rackmount receiver, power supply, microphone clip, battery, zippered pouch, and rackmount kit. A reliable, intuitive, and robust wireless system built for professional performance.
