The Sennheiser EW 300 G4-865-S-GW1 is a premium professional wireless vocal system configured as a complete handheld set, engineered for demanding live sound, broadcast, and installed applications. Operating within a specific UHF frequency range (denoted by GW1, typically 558-608 MHz), this system provides robust RF performance with strong resistance to interference, making it suitable for complex environments such as large concerts, television studios, and major houses of worship. The set is built around a rugged metal handheld transmitter that integrates the Sennheiser MM 865 dynamic supercardioid microphone capsule, paired with a feature-rich true-diversity rackmount receiver, offering a comprehensive, tour-ready solution for critical vocal reinforcement where superior feedback rejection and focused pickup are essential.

The handheld transmitter is designed for durability under constant use, featuring the interchangeable MM 865 capsule, which is renowned for its detailed vocal character and tight supercardioid polar pattern. This pattern provides exceptional rejection of unwanted ambient noise and monitor feedback from the sides and rear, allowing the vocal to cut through dense mixes with clarity. The receiver, part of the evolution G4 300 series, incorporates a sophisticated interface with a high-contrast LCD screen for real-time monitoring of RF spectrum, audio levels, and transmitter battery status. Advanced professional features, including an integrated spectrum analyzer for precise frequency coordination, automatic frequency scan and sync, and adjustable pilot tone squelch, ensure optimal setup and rock-solid stability when operating alongside numerous other wireless systems.

Engineered for flawless sonic performance, the system utilizes Sennheiser's HDX companding technology to provide a wide dynamic range and transparent, full-bandwidth audio with extremely low noise and distortion. The receiver offers both balanced XLR and unbalanced 6.3 mm jack outputs for universal connectivity to any mixing console. Sold as a complete base set, it includes essential professional accessories such as antennae, a robust power supply, and rackmount ears.
