Shure GLX-D+ Dual Band Wireless Rack System with SM35 Headset and GLXD4R+ Half-Rack Receiver

The Shure GLX-D+ Dual Band Wireless Rack System is a professional-grade wireless audio solution designed for demanding live performance and presentation environments. The system combines the GLXD4R+ half-rack digital wireless receiver with the SM35 headset microphone, providing reliable, high-quality audio transmission free from cables. Operating across two frequency bands, the system automatically scans and selects the clearest available channels to maintain a stable connection, even in crowded RF environments. The digital transmission ensures clear audio with low latency, making it suitable for vocalists, presenters, instructors, and worship leaders who require consistent, hands-free operation. The GLXD4R+ receiver features a compact half-rack design with an intuitive LCD display that shows real-time frequency, battery status, and audio levels. It includes both XLR and ¼-inch output connections for flexible integration into mixing consoles or amplifier inputs. The included SM35 is a rugged, over-the-ear headset microphone with a cardioid condenser capsule that provides excellent speech intelligibility and rejection of background noise. Its flexible boom arm allows for precise microphone positioning, and the lightweight, comfortable design ensures it can be worn for extended periods. The system uses rechargeable lithium-ion batteries, with the transmitter offering over 14 hours of continuous use on a single charge. This wireless system is ideally suited for touring musicians, theatre performers, fitness instructors, corporate presenters, and religious institutions where reliable, cable-free audio is essential. The dual-band operation provides greater flexibility and interference avoidance compared to single-band systems, making it a robust choice for venues with multiple wireless devices. The rack-mountable receiver integrates neatly into existing equipment setups, while the durable construction of both components ensures longevity in professional use. It represents a complete, ready-to-use wireless solution that delivers Shure's renowned audio quality and reliability for critical vocal applications.
