Sennheiser SK 300 G4-RC bodypack transmitter unit

General Description

Sennheiser SK 100 G4 Bodypack transmitter for the evolution wireless microphone system. This compact transmitter has a lockable 3.5mm jack socket to connect a wide range of lapel or headworn microphones, or a guitar. The transmitter also has a socket to connect a (optional) remote mute switch.

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 best that the G4 300 series has to offer. This bodypack is compatible with any Sennheiser lapel or headband microphone and a programmable mute button on the microphone lets the user decide when it is time to go “on-air.”

The wireless Sennheiser G4 ew 300 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.
