The Sennheiser EW 100 G4 Lavalier Mic Set is a complete professional wireless system configured for discreet and reliable speech capture, ideal for presenters, educators, corporate speakers, and broadcast applications. Operating within the 516 to 558 MHz UHF frequency band, this system delivers stable RF performance with strong resistance to interference, making it suitable for use in environments like conference halls, lecture theaters, houses of worship, and small studio productions. The set includes a bodypack transmitter, an omni-directional lavalier microphone, and a compact true-diversity receiver, providing an all-in-one solution that is ready for use out of the box, simplifying setup for users who require a reliable wireless link without complex configuration.

The core of the system is the bodypack transmitter, designed with a robust housing and a secure, locking 3.5 mm mini-jack connector for the supplied tie-clip lavalier microphone. This microphone is optimized for vocal clarity, offering a natural frequency response that enhances speech intelligibility while effectively minimizing handling noise. The portable receiver features a clear LCD or LED display for monitoring signal strength and battery status, along with essential controls for channel selection and output level adjustment. Its true-diversity reception system utilizes two internal antennas to intelligently switch to the strongest signal, significantly reducing the risk of audio dropouts as the presenter moves throughout the space.

Engineered for user-friendly operation and professional audio quality, the system employs Sennheiser's wide-band companding technology to deliver transparent sound with a full frequency response and low noise. The receiver offers both balanced XLR and unbalanced 6.3 mm jack outputs, providing flexible connectivity to mixers, powered speakers, or camera inputs. Often supplied with necessary accessories like a power supply and carrying case, the EW 100 G4 Lavalier Set offers a practical and dependable wireless solution for anyone needing a professional, easy-to-deploy lavalier system that delivers consistent, high-quality audio for spoken word applications.
