Sennheiser SK 100 G4 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.

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.

This versatile wireless bodypack system is the perfect choice for musicians to remain wireless. The state-of-the-art transmitter design features a lightweight metal casing with backlit LCD screen. This system is perfect for electric guitar, but the extended frequency response of the system and wide range of sensitivity adjustment means excellent results with bass guitar or acoustic instruments fitted with a pickup.

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.
