The AVX-MKE2 SET includes a bodypack transmitter with lavalier microphone, the plug-in receiver and accessories so you can operate out of the box with camcorders, as well as DSLR cameras. It features self configuring digital transmission which eliminates time-consuming radio frequency setup and an ultra-compact receiver that rotates around the XLR connector to avoid collision with other devices mounted on your camera. It switches on and off automatically with your camera - saving battery power and matches perfectly to your camera's input sensitivity without having to adjust the audio level on the microphone. From professional wedding video to documentaries, from street interviews to corporate videos, the AVX just works, allowing you to concentrate on creativity.
