The AirLine Synth Earset from Samson is a true diversity UHF wireless system with an ultra-compact AL300 beltpack transmitter, a Qe exercise headset microphone, and an AR300 receiver. The headset microphone plugs into the beltpack transmitter, which sends the audio from the microphone to the AR300 receiver without microphone cables. This AirLine Synth kit gives you everything you want in a wireless system: UHF operation, a good sounding microphone, a true diversity receiver, a very small transmitter, infrared tuning, and automatic frequency scanning. One thing you always have to be mindful of when using a wireless system is interference. To fight interference issues, the AirLine Synth system can be switched to over 300 frequencies. A scanner is built into the AR300 receiver that can automatically find the best available frequency. When a clear frequency has been found, you can adjust the frequency setting in the AL300 transmitter with a wireless infrared transmission. No need to navigate up and down pushing tiny buttons, matching frequency numbers from device to device. The included Qe exercise headset microphone is lightweight and comfortable. The microphone element is moisture resistant, so performers on stage and in aerobic studios don't have to worry about perspiration destroying their microphone. Its size is adjustable to fit anyone, and the microphone can be easily positioned with its gooseneck. The AirLine Synth Earset is a great option for anyone who wants great sound and easy operation in a professional wireless system.
