The Sennheiser SK 100 G3 is a professional UHF bodypack transmitter, a core component of the Evolution Wireless G3 series, designed for reliable wireless audio transmission in demanding live performance, broadcast, and presentation environments. Its primary function is to capture audio from a connected lavalier or headset microphone, instrument, or other line-level source, convert it to a secure digital UHF signal, and transmit it to a compatible receiver. The transmitter is built with robust, lightweight housing suitable for discreet concealment under clothing or for secure attachment to a belt or costume, providing performers and presenters with complete freedom of movement without compromising audio integrity.

Engineered for operational flexibility and clarity, the SK 100 G3 features a comprehensive control set, including an easy-to-read backlit LCD screen that displays critical information such as frequency selection, battery life, audio level, and transmitter gain. It offers a wide selection of user-selectable UHF frequencies within its operating band, allowing for easy coordination within multi-channel systems and avoidance of local RF interference. The transmitter includes advanced features like an adjustable audio input gain, a separate tone for mute activation, and an infrared sync capability for quick and error-free frequency matching with a compatible G3 receiver, streamlining setup in fast-paced production scenarios.

As a industry-standard wireless tool, the SK 100 G3 is valued for its robust RF performance, clear digital audio quality with low latency, and exceptional build quality. It is commonly deployed in theater productions, television studios, corporate events, and houses of worship where dependable, hands-free wireless audio is non-negotiable. When paired with a high-quality microphone element and a corresponding receiver, it forms a complete and reliable wireless link that ensures the performer's voice or instrument is delivered with consistency and clarity, free from dropouts or interference.
