Sennheiser SK 500 G4 Bodypack transmitter unit

General Description

The world famous Sennheiser evolution radio microphone range is now in its fourth generation and has been become the preferred system by most audio professionals

More usable systems per range. As the pros have known for years, having the option of lowering a transmitter’s RF output power helps immensely when simultaneously operating a large number of wireless systems. This transmitter also features wireless sync to link up to a compatible G4 receiver automatically with a push of a button. The revised backlit display provides a wealth of useful information at a glance, even on the darkest of stages.

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.
