Sennheiser EK 500 G4 Pro Wireless Camera-Mount Receiver: GBw (606 to 678 MHz)

The black EK 500 G4 Pro Wireless Camera-Mount Receiver from Sennheiser is the latest addition to their evolution series of wireless receivers. It operates in the UHF frequency range and can be used with a companion transmitter and microphone (sold separately), as part of a wireless RF transmission system for live stage, theatre, film, video, and presentation applications.

The camera-mount receiver—with adaptive diversity technology—features 2000 frequencies and is tunable in 25 MHz steps. There are 20 fixed frequency banks with up to 32 compatible frequency presets and 6 user banks with up to 32 user-programmable frequencies. This receiver is built with a menu-driven backlit LCD display showing current frequency, frequency bank and channel number, metering of RF level, volume level, line output level, lock status, battery status, muting function, and more.
