Because of its point source technology, good directivity, the chance of acoustic feedback is also very small.
The main features of the conference discussion system: conference system host can be installed directly on the 19-inch standard rack; conference chairperson machine and on behalf of the machine comes with a connecting cable, using hand-holding cable connection; gooseneck conference microphone; double headset socket, the chairman of the priority, speaking LED instructions; serial 9-bit speaker unit, whistle suppression, microphone automatic shutdown; auxiliary audio signal input and output functions, easy to connect other equipment; can be connected to the audio signal input and output functions, easy to connect to other equipment; can be used in a variety of ways. function, easy to connect other equipment; access to teleconferencing; chairman unit can be used to control the priority button to control the speaking order, control the atmosphere of the meeting, while the speaking seat can be selected 1, 3, 6; with recording output (output amplitude can be adjusted) connected to the recorder function, but also external sound amplification equipment; on behalf of the chairman of the microphone volume can be adjusted to facilitate the adjustment of the sound size, to control the sound pressure on the scene; on behalf and Chairman of the unit is equipped with a speaker volume control, easy to adjust the volume of various units of the speaker; host unit has a microphone input port, and the amplitude can be adjusted, can be connected to the wired microphone and wireless microphone and so on.
Video system: large screen is the first choice, the current feasible program more projectors, more in line with the current situation. In the multimedia conference said the bigger the better the projection screen, but due to the limitations of the height of the room, the size of the projector screen can only be the height of the room in the location of the conference table. The height of the lower edge of the screen can not be in the end, otherwise the speaker will block the screen. Generally 1.2 meters high, that is, room height minus 1.2 meters is the height of the screen. In fact, the upper edge of the screen is impossible to stick to the roof, the screen box, projector hangers and so on still need some height, about a few dozen centimeters. The optimal viewing distance is roughly 4-6 times the height of the screen, equivalent to 2.4-3.6 times the diagonal length of the screen. In the design should take full account of the number of multimedia conference room and the relationship between the height of the room.
Multimedia conference room is different from the general multimedia classroom, first of all, the equipment used are high-grade, complex. To make the equipment to play the best performance, which requires specialized professionals to operate.
