Sennheiser Wireless Lavalier Microphone System Cardioid

The Sennheiser 509641 is a wireless lavalier microphone system built for anyone who needs reliable speech reinforcement without the hassle of cables. It pairs the discreet ME 4 cardioid clip-on microphone with a sturdy bodypack transmitter and a matching diversity receiver, forming a complete package that is ready for stages, lecture halls, houses of worship, and on-camera work.

The included ME 4 capsule captures speech with a cardioid pickup pattern that focuses on the voice and helps reject ambient noise from the sides, so announcements and presentations remain intelligible even in lively rooms. Because the microphone clips securely to clothing, presenters can speak naturally and keep their hands free.

Wireless performance remains solid thanks to transmission range up to 100 meters and operation in a stable UHF band that offers 42 MHz of tuning bandwidth. Up to 20 channels can run at the same time, which is helpful when multiple speakers or performers need their own systems in the same venue.

Setting up is quick. Power on the units, press the infrared sync button, and the transmitter and receiver share frequency information automatically. During the event, the lightweight aluminum bodypack stays unobtrusive, while an integrated mute switch lets the talent silence the microphone without walking to the mixer.

Whether you are organizing a corporate presentation, leading worship, teaching a class, or filming an interview, the Sennheiser 509641 provides the clarity, range, and ease of use that keep the focus on the message rather than the gear.
