What equipment does a modern conference room generally have?

Conference equipment: video (TV/plasma display, projector/video display stand, DVD/ VCR).

Audio (CD/MD, power amplifier, mixer, microphone, etc. ).

Data equipment (computers) and other related equipment.

Environmental equipment: temperature and humidity regulator, lighting, electric projection screen, electric curtain, electric door, electric elevator, etc.

One microphone and two speakers can hold a meeting, which is a traditional meeting mode that has been used for many years. In the process of human communication, 55% of effective information depends on visual effects, 38% on sound, and only 7% on content. So using only one voice to express it is far from meeting the requirements of modern conferences. Modern meetings require concise and vivid expression of participants' ideas and vivid and clear display of their products. The above contents are also elaborated in professional terms: high-quality audio signals, high-definition video static and dynamic pictures, accurate images and physical data to express the participants' ideas.
