Sennheiser EK 500 G4 camera-mount radio microphone receiver

General Description

Evolution wireless has been the industry standard for flexibility, ease of use and reliability for wireless systems for years and the new and improved G4 system looks to continue this trend.

Portable components always work easiest when you do not have to think about them. This was the basis on which the EK 500 G4 was developed. Its adaptive-diversity technology provides excellent reception at all times. This receiver is designed to securely attach to a camera’s shoe using a camera adapter. The EK 500 G4 also can synchronize to a G4 transmitter within seconds.

The wireless Sennheiser G4 ew 500 range is available in the following frequency ranges:

Range Aw+ = 470 - 558 MHz
Range Gw = 558 - 626 MHz 
Range GBw = 606 - 678 MHz
Range Bw = 626 - 698 MHz 
Range Cw = 718 - 790 MHz 
Range Dw = 790 - 865 MHz

Only Range GBw (channel 38) and Range Dw (channel 70) systems are available for purchase on the online shop. The other frequency ranges are available by special request for fixed site licence applications. Range GBw includes Channel 38 which is the most reliable solution for portable wireless microphone systems. (Please Note. Channel 38 use requires a licence. For more information please contact us or visit here. Range Dw includes Channel 70 which is for legal licence-free use in the UK and Europe.
