About the BY-WM8 System

It’s a completely portable, camera-mountable wireless system for capturing wireless audio. It can be used in several environments for video, field recording, interview, broadcast TV, and more.

UHF-More Channels, Less Interference

UHF band wireless mics are able to accommodate more wireless channels than 2.4 GHz. It is difficult to fit more than 12 channels in 2.4 GHz. Plus, there is simply less spectrum available. About 80 MHz is up for grabs in 2.4, while more than 200 MHz is available in UHF
