The Shure GLXD124R+/85-Z3 is a comprehensive professional wireless system that combines dual-band digital wireless technology with a choice of premium microphone capsules in a ready-to-deploy package. This combo system typically includes a GLXD4+ dual-channel rack-mount receiver operating on both 2.4 GHz and 5 GHz bands for intelligent interference avoidance, paired with two different handheld transmitters—often one with a vocal-focused capsule (like a Beta 58A) and another with an instrument-friendly capsule (like a Beta 57A). This provides immediate flexibility for a vocalist and a guitarist, or two vocalists with different tonal preferences, within a single, interference-resistant wireless ecosystem.

The system leverages the GLX-D advanced digital platform to deliver studio-quality audio with ultra-low latency and a wide dynamic range. The receiver's full-color LCD provides clear metering and status for both channels, while an Ethernet port enables remote control and monitoring via optional software. The included transmitters feature OLED displays and rechargeable lithium-ion batteries. The "85-Z3" designation often refers to a specific bundled configuration of microphone models. By automatically navigating crowded RF spectra, this dual-band system offers exceptional reliability in environments saturated with Wi-Fi and other wireless traffic, making it suitable for demanding venues like urban clubs, churches, and theaters.

This combo system is an ideal, all-in-one solution for touring bands, worship teams, and rental companies seeking top-tier wireless performance without the complexity of individual component selection and frequency coordination. It provides the tools for two critical channels, ensures their interference-free operation, and simplifies setup and management, allowing performers to focus on their craft with confidence.
