The Sennheiser EW 100 G3 SKM Microphone is a professional wireless handheld system from the Evolution Wireless G3 series, designed to deliver reliable, high-quality audio for vocalists and presenters in live sound and installed applications. Operating within the 516 to 558 MHz UHF frequency band (Band A), this system offers stable RF performance with strong resistance to interference, making it suitable for environments such as houses of worship, corporate events, and medium-sized venues. The system centers on a rugged metal handheld transmitter that integrates an interchangeable dynamic microphone capsule, typically the MM 835 cardioid capsule, known for its smooth vocal response and effective feedback rejection. Paired with a true-diversity receiver, it provides a complete, ready-to-use solution for critical vocal reinforcement.

The handheld transmitter is built for durability under frequent use, with the microphone capsule securely attached via a threaded connector. It features intuitive controls for power and channel selection, with a clear LED display indicating battery status and transmission activity. The accompanying receiver, available in rackmount or portable form factors, incorporates a user-friendly interface with a backlit LCD screen for monitoring RF signal strength, audio levels, and transmitter battery life. Key features like automatic frequency scanning to find open channels and pilot tone-based squelch ensure straightforward setup and stable, quiet operation by muting the receiver output in the absence of a valid signal.

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 mixing console, powered speaker, or recording interface. Known for its robustness and consistent performance, the EW 100 G3 SKM system has been a trusted choice for musicians, speakers, and audio engineers worldwide, offering an accessible entry point into professional wireless technology that delivers the clarity, reliability, and user-friendly operation associated with the Sennheiser name.
