The Sennheiser ew100G3 is a professional wireless microphone system from the Evolution Wireless G3 series, renowned for its reliability, audio quality, and user-friendly operation in live sound, presentations, and installed applications. This system typically comes configured as a set including either a handheld transmitter with a dynamic microphone capsule or a bodypack transmitter for use with lavalier or headset microphones, paired with a compact true-diversity receiver. Operating on a stable UHF frequency band (specific range varies by regional model, e.g., 516-558 MHz for Band A), it provides robust RF performance with strong resistance to interference. The system is engineered to deliver clear, transparent audio, making it a trusted choice for vocalists, presenters, and performers in venues ranging from houses of worship and conference centers to small and medium-sized stages.

The handheld transmitter is built with a durable metal body and houses an integrated, interchangeable dynamic capsule, such as the MM 835 cardioid, known for its smooth vocal response and effective feedback rejection. The bodypack transmitter is designed for discreet use and features a secure locking connector for external microphones. The accompanying receiver, available in portable tabletop or rackmountable formats, features a clear backlit display for monitoring RF signal strength, audio levels, and transmitter battery life. Key features include automatic frequency scanning to find the clearest channel and a pilot tone-based squelch that mutes the receiver output in the absence of a valid signal, ensuring quiet and reliable operation.

Engineered with Sennheiser's professional audio standards, the system utilizes wide-band companding technology to deliver a full frequency response with low noise. The receiver provides both balanced XLR and unbalanced 6.3 mm jack outputs for flexible integration into any sound reinforcement system. Known for its robustness and consistent performance, the Sennheiser ew100G3 has been a workhorse for musicians, speakers, and audio engineers worldwide, offering an accessible entry point into professional wireless technology that delivers the clarity, reliability, and ease of use associated with the Sennheiser name.
