- Description
Reliability and performance
Eventually, you’ll get to a level in your career as an engineer or musician when the size stage you’re performing on demands more than an entry-level wireless system. You simply need more reach, more power and more reliability than what a 2.4 GHz system will allow. Enter the evolution wireless G4 100 Series—the next level in your journey as a stage professional.
Feature-rich and built to last
The evolution wireless G4 100 Series is packed with features that make it possible to get you up and running fast and efficiently. Use the Easy Setup function to automatically scan and select the best frequencies around you and take full advantage of the UHF spectrum. With up to 100 meters of range and a battery life of 8 hours, it’s easy to see how the durably constructed ewG4 transmitters and receivers will perform when you need them to.
Differences between the sets
The 835, 845 and 865 vocal microphone capsules are all great options and vary depending on your needs. While the 835 is ideal for most stages and features a cardioid polar pattern that rejects unwanted stage noise from the sides and rear, the 845 features a super-cardioid polar pattern that offers even more rejection and isolation for your vocal performance. The 865 introduces a condenser super-cardioid capsule, offering more sensitivity and clarity than a traditional dynamic capsule like the 835 or 845.
