エクセリ本社

Achieves stable simultaneous calls with 1.9GHz DECT technology. A wireless intercom that supports real-time collaboration in events, stages, and security sites.

The ReaCom ALVO 1.9 is a real-time wireless communication system manufactured by B-EAR. It adopts the 1.9GHz DECT method, enabling stable simultaneous communication with minimal interference even in crowded event venues, exhibitions, stages, and sports arenas. It supports simultaneous communication for up to 10 people per group. Additionally, by connecting master units from different groups with a USB Type-C cable, it allows for operation with even larger numbers of participants. It accommodates up to 10 group configurations and supports room division within groups. Even when operating in multiple areas, it can register up to 4 groups, and switching between groups can be done smoothly with a single mode button. The master unit and subunits can be easily identified by the color of the main unit and the ID display on the LCD screen (master unit: "M", subunits: "01–09"). It is equipped with environmental noise-canceling technology ENC 2.0, which reduces surrounding noise in real-time, ensuring clear voice communication even in noisy environments.
