Sennheiser EM 100 G4-A1 Wireless Microphone System Receiver

The Sennheiser 509652 is the EM 100 G4-A1 wireless microphone receiver that anchors the Evolution G4 system with consistent radio performance and clear audio. Engineers and performers can rely on it during club shows, worship services, corporate meetings, and broadcast productions.

Its true diversity design monitors two separate antenna signals and automatically chooses the stronger one, so dropouts stay out of the mix even when a presenter or musician walks across a challenging RF zone. The receiver sits in a half rack chassis made from solid metal, giving it the durability required for frequent setups and road travel.

A backlit LCD shows frequency, RF strength, audio level, and battery life, making adjustments quick even in low light. Infrared sync pairs the receiver with a compatible G4 transmitter in seconds, and a fast frequency scan can coordinate up to twelve receivers on the same stage without manual channel planning.

The 470 to 516 MHz tuning range helps you find clear spectrum in the crowded A1 band, while a 110 dB(A) signal to noise ratio keeps every vocal nuance intact. XLR and 6.35 mm audio outputs connect to mixers or recorders, and BNC antenna jacks make it easy to integrate an antenna splitter when you expand the system.

Everything needed for installation ships in the box, including two rod antennas, a universal power supply, an RJ-10 data cable, and a rackmount kit.
