The intelligent conference speech mode adapts to the needs of different types of conferences:

1. Intelligent limit: The number of units that can be opened at the same time can be set to 1-6. After the limit is reached, one person is allowed to apply and wait for a countdown of 30 seconds. When there is a message, the microphone will automatically enter.
2. First-in, first-out(FIFO): the number of speaking units is 1-6, and the microphone is opened later to cover the earliest opened microphone.
3. Smart application(APPLY): When the applicant presses the button to speak, the application will count down for 30 seconds, and the microphone pole light and microphone indicator will flash at the same time, and the chairman will short press the priority button to approve the application to open the microphone. Short press once to approve—person, the opening order is determined by the application order, after reaching the number of speakers, one microphone is allowed to enter the application state, and the last opening microphone automatically covers the earliest open unit (in this mode, the chairman microphone does not have a temporary mute function to represent the interrupt)
4. Open and Mo mode(FREE): the number of units that can be turned on at the same time is not limited (please do not turn on all microphones at the same time for a long time)
5. Time-limited speech: You can set the participant's speech time limit to 15 seconds to 60 minutes, and the microphone will be automatically turned off when the time reaches
6. C-ONLY: only the chairman's microphone is allowed to open to speak, and all representative units cannot be opened.
7. Voice-activated start: the unit is turned on by voice control, and the voice-activated threshold can be adjusted by the host
8. Automatic test: Set the number of units to be tested. After confirming the test, each microphone indicator flashes for 2 seconds in sequence, and the test is completed and the original state is automatically reset.
