The lightweight BY-WM8 PRO-K3 includes a handheld transmitter microphone along with a two-channel receiver that's ready to plug into your DSLR/mirrorless camera, or audio recorder. The receiver's two-channel capability allows you to expand your system in the future with an additional transmitter and microphone (available separately) for 2-person interviews—with no additional receiver necessary.

The microphone's directional cardioid polar pattern helps to reject unwanted background sound, making it ideal in loud environments such as trade-show floors, busy public areas, or sporting events. A headphone output on the receiver enables real-time audio monitoring, especially useful if your camera lacks a headphone output.

The system operates at a range of 300' with 48 selectable frequencies that provide options for finding a clear channel in case of signal interference. The transmitter and receiver feature locking connections to eliminate unintended cable disconnects and they both run on two AA batteries for up to 6 hours of operation.
