1. The host is equipped with a display, making operation more convenient and intuitive.

2. Radio frequency control, with audio frequency ranging from UHF780-850MHz, makes installation, demolition, and movement more convenient without damaging the original decoration. The effective working distance is 60 meters.

3. The system comes with 20 frequency channels that can be switched freely, which can avoid interference from other frequencies.

4. The host can connect to 248 representative units and 2 chairman units, with a maximum of one chairman and two representatives or two chairmen and one representative simultaneously. The system has a select in, first out, chairman specific mode, and the number of representative speakers can be set to 1, 2, or 3 as needed.

5. The host is connected to the camera, and computer software can be used to achieve video tracking function. The host comes with a standard definition switching interface of 4 in and 2 out, which allows for up to 4 cameras without the need for additional equipment. It can also be connected to an external high-definition video switcher, achieving the use of up to 6 high-definition cameras, suitable for various venue needs. It supports multiple camera protocols, such as EVI-D70, Yan, Pelco D, Pelco P, and can be connected to the camera through 232 and 485. The screen freezing function can also be set to freeze the screen when the camera rotates, so that there will be no images during the camera rotation process.

6. By using the one click shutdown function of the host, all units can be turned off at once, eliminating the tedious operation of manually shutting down units.

7. The host has two audio outputs, namely XLR balanced output and 6.35mm output, suitable for connecting various sound reinforcement devices.

8. The host is equipped with a USB recording box port, which can connect to dedicated recording devices for real-time recording of meetings.
