Boya UHF Dual Lavalier Microphone Wireless BY-WM8 Pro-K1

The Boya UHF Dual Lavalier Microphone Wireless BY-WM8 Pro-K1 is a wireless microphone set, which is ideal for interviews, ENG/EFP, movie productions and more. The BY-WM8 Pro-K1 is an upgrade of the BY-WM6 and BY-WM8 wireless duo-microphones. The pro-version, for example, has a much lower distortion rate, which means that the sound is less distorted. This has significantly improved the sound quality. The set is also lighter in weight than its predecessor.

Both the transmitter and receiver use two AA-batteries (not included). This allows you to use the microphone set for up to 6 hours. The BY-WM8 Pro-K1 has a maximum range of 100 meters, if there are no obstacles between the transmitter and receiver. You can also add a second transmitter later (see optional accessories). The BY-WM8 Pro-K1 can be used with DSLR-cameras, camcorders and audio recorders. In addition, a smartphone adapter (see optional accessories) allows you to easily connect your mobile phone to the receiver. The wireless frequencies are 556.71 MHz-575.98 MHz and 576.39 MHz-595.66MHz.
