Ideal for broadcasting, training, meetings, and more. This full-duplex intercom system with four beltpack transceivers allows two-way communication at a range of up to 300 m. It includes a base station, four beltpack transceivers, and five headsets. The base station powers from an included AC power adapter with a 4-pin XLR connector or from optional L-series batteries via the dual-battery plate built into the top of the base station. With this full-duplex intercom system, audio transmission starts once you speak, and there is no need to press a button before talking (case for a walkie-talkie). The base station and beltpacks all come with a HD OLED display, which can display important information including signal strength, remaining battery power, and connection status in real time.
