The Sennheiser EW 500 G4 is a professional-grade UHF wireless microphone system representing the fourth generation of the acclaimed Evolution Wireless series, designed for demanding live sound, theatrical, and corporate presentation applications. This specific configuration pairs the EW 500 G4 rack-mountable dual-channel receiver with the SKM 500 G4-935 handheld transmitter, which integrates a premium supercardioid dynamic microphone capsule. Operating within the robust AW+ frequency band (470-558 MHz), the system offers extensive frequency agility and coordination capabilities, allowing users to navigate crowded RF environments and find clear channels for reliable, interference-free operation. The system is engineered to deliver the superior audio quality, robust RF performance, and operational ease that audio professionals depend on for critical events.

The heart of the system is the EM 500 G4 dual receiver, which features a sophisticated true diversity design with two independent RF front-ends and a high-gain antenna array. This design ensures maximum signal integrity and stability by continuously selecting the antenna with the best signal, effectively mitigating dropouts and multipath interference. The receiver provides comprehensive system control via a high-contrast LCD screen and intuitive navigation, offering features like an integrated frequency scanner, pilot tone-based squelch, and adjustable RF power output. The rack-mountable unit is built for integration into professional touring racks or installed systems, offering balanced XLR and unbalanced 6.3 mm jack outputs alongside digital networking via an optional plug-on USB interface for remote control and monitoring from a computer.

The SKM 500 G4 handheld transmitter is constructed with a durable metal body, housing professional-grade circuitry and the renowned MD 935-II dynamic capsule. This supercardioid capsule provides excellent feedback rejection and isolation from ambient stage noise, capturing a clear, detailed vocal sound with a pronounced presence peak tailored for live vocal reinforcement. The transmitter features an intuitive menu with a bright OLED display for monitoring battery life, RF level, and audio settings. With features like a programmable mute switch, adjustable microphone sensitivity, and support for both AA batteries and rechargeable solutions, the SKM 500 G4 is designed for ease of use and performer confidence. Together, this system offers a perfect balance of broadcast-quality audio, robust wireless transmission, and professional features, making it a benchmark in its class for reliability and sound.
