Operating in the 542 to 566 MHz frequency band, the Samson AirLine AHX Wireless UHF Fitness Headset System features a CR99 UHF receiver, an ATX transmitter, and a Qe dual-ear fitness headset condenser microphone. The frequency-agile UHF system can be used to capture audio in various environments and offers up to 300' of reliable performance for singers and other active performer applications.
The transmitter is small enough to fit in the palm of your hand, and is powered by the built-in rechargeable battery. It clips to your belt or shirt pocket, and connects to the TA3M mini-XLR jack on the Qe bidirectional headset microphone, which provides clear audio reproduction and sound rejection at the sides of the capsule.
The system's rack-mountable CR99 receiver provides 80 selectable channels across 24 MHz, 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. Its XLR and 1/4" outputs ensure compatible connectivity with a variety of mixers and PA systems.
