беспроводной конференц-системы SW-60

Lipo sw-60 Wireless conference System can support 50 units to be used together,meet different kinds of meeting rooms. The SW-60/60A/60B/10Wireless discussion system is a discussion system for using in meeting and conference venues with a limited number of participants. The SW-60/60A/60B/10 Discussion System consists of: One Control and power supply Unit (SW-60) Maximum 50 units ,includes one or more chairman unit(s). Wireless access point SW-10 Extension cables if required (5m or 10m). Peripheral audio and /or telecommunication equipment.The system has the functions below: (1)open mode:to select the maximum number of delegate microphones to be actived simultaneously(1,2,3 or 4).The microphone must be switched on or off manually by pushing the button on the delegate unit. (2)override mode:only one deleagte microphone can be activated.If a new delegate pressed his microphone button,the microphone unit of the current speaker will be switched off. (3)chairman only mode:only the chairman units can be activated. (4)test mode:for proper installation check.All the light rings and LEDs of the connected units will lit,if properly connected. (5)turn off mode:to turn off all units at the same time.
