The Airline ALX Wireless UHF Lavalier System from Samson features a CR99 UHF receiver with rackmount kit and AC adapter, an ATX transmitter, and an LM8 lavalier microphone. The frequency-agile UHF system can be used to capture audio in various environments and offers up to 300' of reliable performance for speech and other active presenter applications.

The transmitter is small enough to fit in the palm of your hand and is built with a rechargeable battery. It clips to your belt and connects via a P3 mini-XLR connector to the low-profile LM8 omnidirectional lavalier microphone, which provides clear reproduction regardless of the position of the capsule relative to the sound source.

The system's rack-mountable CR99 receiver provides 80 selectable channels of performance and is equipped with a true RF diversity design that minimizes dropouts. Built with tone key technology, the receiver prevents unwanted noise when your transmitter is off or out of range.
