Operating in the 542 to 566 MHz frequency band, the Samson AirLine 99m AH9 Wireless UHF Fitness Headset System features an AR99m UHF micro receiver and an AH9 micro transmitter attached to 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 powered by a built-in rechargeable battery and mounted on the Qe bidirectional headset microphone, which provides clear audio reproduction and sound rejection at the sides of the capsule.

The AR99m provides 100 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, 3.5mm, and 1/4" outputs ensure compatible connectivity with a variety of mixers and PA systems. Also, a side-panel USB Type-A port allows for convenient charging of the transmitter or a mobile device, or the addition of a Samson XPD wireless system (available separately).
