The BOYA BY-WM8 Pro-K2 Dual-Channel Wireless Lavalier System consists of two wireless bodypack transmitters along with two omnidirectional lavalier microphones and one receiver to capture high quality sound; making it ideal for broadcast and film, ENG, talk shows, conferences between two people; having both transmitters sound fed through to the receiver.
The camera-mountable receiver features a wide-switching RF bandwidth, an easy-to-read and convenient LCD display, a 3.5mm headphone jack that enables real-time monitoring. The transmitter that feeds the sound through is equipped with a crystal-controlled PLL synthesizer, a 1/8 mic input, a 1/8 line-in jack, and a muting function. Between the two devices it allows a 100m working range.
Included with this powerful microphone system is a shoe-mount adapter, a single 1/8 to XLR output cable, a single 1/8 to 1/8 output cable, and a carrying case.
