Trạm điều khiển chính 2 kênh - hệ thống liên lạc nội bộ không dây 5Ghz

 - Up to 32 Belt Packs can be paired up with each Base Station. and especially a BS-250 can have 11 full-duplex audio paths. By connecting two or more base stations together. the allocated Belt Packs and audio paths can be multiplied.
 - Under “Shared Mode”. more than 32 and up to 128 Belt Packs can be registered and operated.
 - Under “Free mode”. unlimited number of Belt Packs can be "paired up" to Base Station at the same time. However. each base station’s monitoring capacity is limited to only 32 Beltpacks.
 - Each Base station can monitor Battery level. Received Signal Strength Indication(RSSI). MIC gain. and connection status of original 32 Belt Pack.
 - Working with wired Intercom. The BS-250 can be operated jointly with wired intercom systems through utilizing AUX In and AUX Out connections.
