The revolutionary AirLine "plug-in" AG1 transmitter is designed for traditional end-mount inputs. Less than half the size of conventional body packs, this miniaturized transmitter runs on a tiny triple-A battery with 14 hours of battery life. It features an array of on-board controls: A Power On/Off and Mute switch, red/green LED for Power On/Off, a Peak LED and an Input Level control for different pickups. And UHF (Ultra High Frequency) means clearer frequencies with less interference.
