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

threshold can be adjusted by the host
- 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.
