Sennheiser EK 100 G4 Camera-Mount Wireless Receiver

The Sennheiser 509519 is a camera-mount wireless receiver that brings dependable, professional-level sound to DSLR rigs, cinema cameras, and portable recorders. Its chassis is made of metal yet remains light enough to sit on a hot shoe all day without adding noticeable weight. Adaptive diversity reception keeps the signal steady at distances up to 330 feet, letting you follow interview subjects, wedding couples, or on-the-street talent while capturing clean audio.

Getting started is quick. Power the unit, scan for a clear channel within the 42 MHz tuning range, then hold your transmitter close to the receiver for an infrared sync that completes in seconds. A backlit screen presents frequency, audio level, and battery life clearly whether you are outdoors at noon or in a dim venue.

The locking 3.5 mm output secures neatly to most cameras, and the included XLR adapter feeds professional camcorders or field mixers. Two AA batteries deliver up to eight hours of operation, plenty for a full shooting day. Because the EK 100 G4 works with every Evolution Wireless generation from G1 through G4, it drops straight into existing Sennheiser kits without fuss.

Whether you create YouTube content on the go, produce documentaries in dynamic environments, or film weddings that demand reliable gear, this receiver keeps your audio consistent and your workflow simple.
