  ⑴Video display stand: can convert manuscripts, pictures, real objects, etc. into video signals, and put them on the projector through the projector.


   on the screen for everyone to watch. The video showcase shall have functions such as automatic iris adjustment, manual or dynamic focusing, and image zooming.


  ⑵Laser disc player: DVD player is the first choice, it has higher definition, and is compatible with VCD, SVCD, and can play discs in multiple formats.


  ⑶ Multi-standard video player (recorder).


  ⑷Recording deck: generally use dual decks.


  ⑸ Radio: It is better to use independent radio head equipment.


  ⑹Satellite or cable television receiving system: used to receive broadcast resources.


  D) Camera system: It can record live speech scenes through a video recorder, which is also convenient for live broadcasting.


  E) Sound reinforcement equipment: It is better to use professional equipment. Professional audio equipment is more suitable for the meeting environment and requirements due to its large dynamic range, high voice fidelity requirements and good stability.


  ⑴Amplifier: It should have an effective output power of 2*100W or more.


  ⑵Speaker material: You can choose speaker, column or ceiling speaker. The design of its quantity and distribution should be based on the principle of obtaining a uniform indoor sound field, soft sound, and clear voice.


   (3) Conference microphone and wireless microphone: The quality of the microphone directly affects the conference effect. High-performance varieties should be selected.


  ⑷Those who have the conditions may consider configuring a complete set of stage professional audio equipment. It mainly includes the following equipment: high-power amplifiers, mixers, equalizers, effects, professional stage speakers, etc.


  (F) Configure conference system equipment so that it has the functions of speaking, voting, and statistics.

  2. Free training on the use and maintenance of items and maintenance knowledge, and provide technical consulting services.


  Eight. Use and basic maintenance of system equipment


  1. Projector: LCD projector is the most expensive of the multimedia equipment, so we must pay attention to its safe operation and use:


  ⑴ LCD projectors are not suitable for long-term work, and their lamp life is generally 2000 hours. There are two types of bulbs: xenon lamps or metal halide lamps; when metal halide lamps are gradually aging, due to the accelerated loss of red and blue spectra in the halogen lamp spectrum, the color will shift to blue. The color stability of the surface xenon lamp is as long as the lamp life. In addition, the price of the xenon lamp is much higher than that of the metal halide lamp.


  ⑵After using the projector, you must first use the "STANDBY" function key to turn off the projector's lamp, and let it cool down before turning off the power. Generally speaking, the power control of the central control system should have the automatic power-off function of the projector.


  2. Projection screen: The installation must be level and flexible, otherwise it is easy to damage the ring motor. It is not foldable, and the main time should be retracted after use to avoid staining and affecting the viewing effect.


  3. Wireless microphone: After use, you should pay attention to turn off the power of the microphone to prevent the battery from running out of power too quickly due to long working hours


  4. Power supply: After the power of all equipment of the system (including computers and projectors) is turned off, turn off the power of the central controller, and finally turn off the main power.
