The Sennheiser EW100G2 is a professional wireless microphone system from the Evolution Wireless G2 series, designed to provide reliable, high-quality audio for a variety of vocal and instrumental applications. Operating within the 518 to 554 MHz UHF frequency band, this system offers stable RF performance with strong resistance to interference, making it suitable for live sound, presentations, and installed environments such as houses of worship and conference rooms. The system is highly modular, typically configured as a set including either a handheld transmitter with an integrated dynamic microphone capsule or a bodypack transmitter for use with lavalier or headset microphones, paired with a compact true-diversity receiver. This flexibility provides users with a complete, ready-to-use wireless link that balances professional performance with accessible operation.

The handheld transmitter variant features a durable metal body housing an integrated, interchangeable microphone capsule, such as the MM 835 cardioid dynamic capsule known for its smooth vocal reproduction and excellent feedback rejection. The bodypack transmitter is designed for discreet use, featuring a secure locking connector for external microphones. The accompanying receiver, available in portable tabletop or rackmountable formats, incorporates a clear backlit display for monitoring RF and audio signal strength, transmitter battery life, and system status. Key user-friendly features include automatic frequency scanning to locate clear channels and pilot tone-based squelch to mute output in the absence of a valid signal, ensuring straightforward setup and quiet, reliable operation.

Engineered with Sennheiser's professional audio standards, the system utilizes wide-band companding technology to deliver transparent sound with a full frequency response and low noise. The receiver provides both balanced XLR and unbalanced 6.3 mm jack outputs for flexible integration into any sound reinforcement system, mixing console, or recording interface. Known for its robustness and consistent performance, the EW100G2 series has been a workhorse for musicians, presenters, and audio engineers, offering a trusted entry point into professional wireless technology that delivers the clarity and reliability associated with the Sennheiser name.
