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.

You can only sound better if you hear yourself better. Wireless monitoring is taken to the next level of perfection with the Sennheiser G4 monitoring system. Added features of this stereo transmitter include the valuable integrated 5 band equalizer for extra control of the sound. New pass-through sockets for the audio signal enable the audio feed from a console to be routed to other devices in the chain, simplifying setup. The enhanced audio frequency response of 25 to 15,000 Hz means the sound the performers hear is the most realistic and life-like a wireless monitor system has ever had to offer.

The wireless Sennheiser G4 SR IEM is available in the following frequency ranges:

A: 516 - 558 MHz
G: 566 - 608 MHz
GB: 606 - 648 MHz
B: 626 - 668 MHz
C: 734 - 776 MHz
D: 780 - 822 MHz
E: 823 - 865 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.
