Sennheiser ew IEM G4 Wireless Monitor System (G: 566 to 608 MHz)

The Sennheiser 509610 is a monitoring system that uses in-ear technology and operates wirelessly within the G band from 566 to 608 MHz. It gives musicians, actors, and worship leaders the freedom to move while hearing a personal mix that stays consistent and clear.

The package brings together a transmitter that fits in a half rack and sends a stereo signal, a rugged bodypack receiver, and a pair of Sennheiser IE 4 earphones. A quick infrared sync links the receiver to the transmitter, and an OLED screen on the transmitter makes navigation straightforward even in low light.

With up to 42 MHz of tuning bandwidth and 1680 selectable frequencies, the system helps you find a clean channel in crowded RF spaces. A transmission range that can reach 300 feet keeps the signal steady on large stages, in theaters, and across houses of worship.

Metal housings protect every component, so the system stands up to daily setups, tear-downs, and travel. A rackmount kit, rod antenna, and two AA batteries come in the box, letting you put the gear straight to work. For multichannel rigs, integration with Sennheiser Wireless Systems Manager software streamlines frequency coordination.

Whether you are touring with a band, running a theatrical production, or managing weekly services, this system offers reliable, high-quality monitoring without the hassle of cables.
