Reliability and performance
Eventually, you’ll most likely get to a point in your filmmaking career when you realize that audio quality is just as important as video quality when it comes to creating compelling content. And at a certain point, reliability and consistency become the top priorities when recording wireless audio while on set or in the field. Enter the evolution wireless G4 100 Series—the next level in your journey as a professional filmmaker.

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 112P, 122P, 135P and 100 ENG sets are all great options and vary depending on your needs. The 112P features our omni-directional ME 2-II lavalier microphone while the 122P features our cardioid ME 4 lavalier microphone. The 135P swaps the bodypack transmitter and lavalier mic for the SKM 100 handheld transmitter and MMD 835 cardioid capsule. For those that need a combination of both for a range of Electronic News Gathering applications, the EW 100 ENG G4 set includes the ME 2-II lavalier and adds the SKP 100 plug-on transmitter for your existing dynamic XLR microphone or a battery powered shotgun mic like the MKE 600.
