Sennheiser EK 100 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 100 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 100 G4 also can synchronize to a G4 transmitter within seconds.

The wireless Sennheiser G4 ew 100 range is available in the following frequency ranges:

Range A = 516 - 558 MHz
Range G = 566 - 608 MHz
Range GB = 606 - 648 MHz
Range B = 626 - 668 MHz
Range C = 734 - 776 MHz
Range E = 823 - 865 MHz
Range 1G8 = 1785 - 1800 MHz

Only Range GB (channel 38) and Range E (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 GB includes Channel 38 which is the most reliable solution for portable wireless microphone systems. (Please Note. Channel 38 use requires a licence.
