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.

The Sennheiser G4 rack receiver is ready for the road with its proven transmission reliability and inspiring flexibility. The true diversity ensures a reliable signal transmission. The EM 100 G4 provides a 42MHz tuning bandwidth as well as instant frequency allocation for up to 12 receivers via infrared synchronisation.

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. For more information please contact us or visit here. Range E includes Channel 70 which is for legal licence-free use in the UK and Europe.

The Sennheiser G4 range of wireless microphone systems are capable of operating simultaneously, intermodulation free, on six frequencies in the licence exempt 863-865 MHz (channel 70) band. These frequencies are;

863.100 MHz
863.400 MHz
