Sennheiser EK 500 G4 Pro Wireless Camera Receiver GW1

The Sennheiser 509553 is a wireless receiver that mounts directly on a camera and gives production teams the consistent, broadcast-quality sound they expect from the evolution wireless G4 system. Built for work in the UHF band between 558 and 608 MHz, it offers up to 32 selectable channels, letting you move quickly to a clear frequency even when RF traffic is heavy.

An adaptive diversity circuit continually evaluates the incoming signal and selects the antenna that delivers the strongest reception, so you spend less time worrying about dropouts and more time focusing on the shot. Range extends to about 100 meters, which covers most sound-stage layouts, outdoor interviews, and live event venues.

Every key setting appears on a backlit LCD that stays readable in bright daylight or a dim studio. Pairing with a compatible G4 transmitter takes only a moment thanks to infrared sync, a feature that speeds up changeovers when talent or locations shift.

The receiver runs for up to eight hours on two standard AA batteries. That kind of stamina is welcome during long documentary days, all-day conference coverage, or multi-set film shoots where battery changes can slow the schedule.

A rugged metal housing protects the electronics from bumps, drops, and the constant mounting and unmounting that come with on-the-go production. At just 130 grams, it adds little weight to a DSLR cage or a shoulder-mounted ENG rig. The kit includes a locking 3.5 mm audio cable, an XLR to 3.5 mm adapter, and a versatile camera mounting set, so you can connect to a wide range of recorders and camcorders right out of the box.

Whether you are capturing dialogue for an indie film, pulling clean audio at a corporate keynote, or covering a fast-moving news story, the EK 500 G4 slot-in receiver delivers dependable performance session after session.
