The Shure GLXD2/SM58 is an integrated digital wireless handheld system that combines the renowned Shure SM58 dynamic vocal microphone with the GLX-D advanced digital wireless platform. This system provides a streamlined, all-in-one solution for performers seeking professional wireless convenience without compromising the iconic sound of the SM58. The handheld transmitter features the same durable forged steel grille and tailored frequency response as the standard SM58, delivering a smooth, present vocal tone with excellent gain before feedback and controlled proximity effect. The integrated digital transmitter operates in the 2.4 GHz ISM band, utilizing adaptive frequency hopping to locate and maintain a clear signal path in environments congested with Wi-Fi and other wireless traffic, ensuring reliable performance for live sound and portable applications.

The GLX-D digital wireless technology offers several key advantages, including crystal-clear 24-bit digital audio transmission with ultra-low latency, ensuring perfect synchronization with other audio sources and no analog companding artifacts. The system automatically scans for the cleanest available channels upon power-up and can seamlessly switch frequencies during operation if interference is detected, all without audible dropouts. The included rackmount receiver provides intuitive visual feedback via a bright color LCD screen, displaying real-time information such as RF signal strength, audio level, and remaining transmitter battery life, which is conveniently powered by a rechargeable lithium-ion battery built into the transmitter body.

Designed for ease of use and quick setup, the system is ideal for working musicians, worship facilities, and mobile entertainers who require a professional, plug-and-play wireless solution. The integration of the SM58 capsule with a sophisticated digital wireless system in a single handheld unit eliminates the need for external adapters or cabling, reducing potential failure points. The Shure GLXD2/SM58 delivers the trusted sonic performance and physical durability of a world-standard microphone with the clarity, reliability, and intelligent frequency management of modern digital wireless, making it a powerful tool for vocalists who demand both legendary tone and wireless freedom.
