System Context
Designed as Part of a Managed Conference System
Smart MIC products are used together as a system: the controller manages roles and modes, terminals capture speech, receivers add wireless access, and expansion hubs scale wired seat counts.
Installation Use
Clear Operation for Formal Meeting Rooms
The system supports structured meetings in council chambers, corporate boardrooms, command rooms, education spaces, and other rooms where speaking order and audio reliability matter.
Project Workflow
How It Fits Into a Smart MIC Project
Connect the system core
Connect the master controller, receiver, expansion hub, and microphone terminals according to the required wired or wireless room layout.
Assign roles and meeting modes
Set terminal IDs, chairman/delegate/VIP roles, speaking limits, request queues, timers, and operating modes from the controller or management software.
Operate the meeting
Participants speak through managed terminals while the system handles microphone state, queue behavior, camera tracking support, and stable speech transmission.
Maintain and expand
Use hot-plug support, network expansion, and monitoring workflows to keep the system reliable as the room grows.
Applications
Where It Fits
Government and council chambers
Role-based chairman/delegate workflows, camera-tracking support, and structured speaking modes fit formal meeting rooms.
Corporate conference centers
Managed microphone operation and clean terminal layouts help executive rooms, boardrooms, and hybrid meeting spaces stay orderly.
Large conference systems
