Operating in the 470 to 494 MHz frequency band, the Samson AirLine 99m AH9 Wireless UHF Headset System features an AR99m UHF micro receiver and an AH9 micro transmitter attached to a DE10x dual-ear 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 presenters, singers, and other active performer applications.
The transmitter is powered by a built-in rechargeable battery and mounted on the DE10x omnidirectional headset microphone, which delivers clear audio reproduction and a low-profile appearance.
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).
