Efficient microphone state management is essential for successful control of meetings. The microphone management software module provides a powerful, simple and easy to use tool for users to control all aspects of the microphone management power from a single control point. Basic function microphones can be controlled by the name (or device number) of the representative. The user can select the microphone (activate the microphone) according to the list of speakers or prepare a list of speakers. The order of representatives in the list of speakers or speakers may be changed at any time before or during the session. It provides search capabilities that allow operators to find specific representatives. In addition, it can assign a notebook status to conference delegates, meaning that they can enjoy privileges not available to other delegates without joining the list of speakers. The user must specify the microphone type for the notebook. Possible types include: • "chairman" for chairman microphone • "button", which means the microphone can be activated by pressing the microphone button. (in this mode, the feed device's "VIP" LED indicator light will turn on.) • "operator", a new generation of microphones with more active representatives activated by the operator, will automatically identify the designated chairman and add it to the notebook. The microphone management module provides many microphone control options. This will have an important impact on how the microphone management module works and how the meeting itself works. These options below: • operator controlled by speech request list (manual), the operator through a request list and response to control list, to represent control through a request list (open), covered by other represented at the receiver to control (first in first out), representative through voice activation function to control each model represents different operating personnel and control level, so can to cover almost all occasions. For example, small informal seminars rarely require operator control, so a model controlled by representatives is ideal. For a large international conference with hundreds of participants, it would be more appropriate for the operator to control it through a statement request. The operator can specify the number of normally activated microphones: one, two, three, or four. Alternatively, you can specify whether a representative is allowed to cancel a speech request or close his or her microphone. The operator can also specify when the representative will speak.
