Sennheiser ew 135-p G4 portable radio handheld microphone camera system

General Description

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

A handheld system designed for field operation: this system is the perfect choice for ENG professionals. The rugged hand-held cardioid wireless microphone provides professional sound quality for interviews and reporting, even under unfavourable conditions. At the camera end of the wireless signal path is the portable and reliable EK 100 G4 adaptive diversity receiver.

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 on-line shop. The other frequency ranges are available by special request for fixed site licence applications. Channel 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). Channel 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
863.750 MHz
864.225 MHz
864.550 MHz
864.975 MHz
