Boya BY-WM8 ProK2 - Dual Channel, Dual Lapel Wireless Microphone System

  • Vendor: BOYA
  • Product Type: Audio

The Boya BY-WM8 ProK2 Wireless Lavalier Microphone is a wireless dual microphone set designed for use with DSLR cameras, camcorders and audio recorders. The BY-WM8 ProK2 is compact, lightweight and uses a UHF frequency. The two microphone sets are equipped with a layer filter to improve the sounds and suppress distortion and background noise. Further, the BY-WM8 ProK2 has an approximate range of 100 metres, provided there are no obstacles between the transmitters and receiver. 

These features make the BY-WM8 ProK2 excellent for interviewing. Also known as the “reporters kit”, the BY-WM8 ProK2 transmitter, microphones and earphones are worn by the interviewers. The receiver can be mounted onto the hotshoe of the camera or camcorder and connected via the connection cable. The receiver is also equipped with an earphone, enabling the cameraman to listen to and control the audio directly. 

The receiver is equipped with a coldshoe connection and a ¼” female screw thread enabling you to mount it onto your camera, light stand or tripod.

The receiver is built with mic and headphone output jacks. The bodypack transmitter includes a MIC jack and LINE IN jack.
