There are two types of sound reinforcement systems for conference venues, one is the multi-function hall sound reinforcement system, and the other is the conference sound reinforcement system. In addition to conferences, reports and other activities, the multi-functional conference room is also a place for employees to perform entertainment and leisure activities, such as singing, dancing, music, drama and other cultural and artistic performances. A high-quality sound reinforcement system is required to cooperate with it, and strive to integrate various The sound source is restored as perfect as possible to ensure the smooth progress of various performances, so that in addition to visually beautiful enjoyment, actors and audiences can also enjoy the sense of nature and the beauty of art in the sense of hearing. The designed sound reinforcement system has a higher and more uniform sound field design, which should have better music signal clarity and fullness.

　　The main speakers, subwoofer speakers, listening speakers, auxiliary speakers, supplementary speakers, sound-pull speakers, etc. plus audio processing equipment, power amplifiers, and tuning equipment are usually configured according to the size and shape of the venue. Equipped with several sets of wireless handheld and lavalier microphones. There are three points to note for this:

　　1. This kind of place is not a professional performance hall. Generally, there is no sound design in the building. You can only use the soft decoration as much as possible to obtain a better sound field and make the electroacoustics meet the requirements.

　　But there is no soft decoration, such as the court's trial hall. Almost all courtrooms in the country are 200-300 square meters small, nearly 1,000 square meters large, and 5-7 meters high. In order to reflect the solemnity, the decoration is used All of them are hard materials, and they are square and square, and all are parallel to each other. The ground is terrazzo or wooden floors, and the walls are all wrapped in hard wood. This type of sound reinforcement taboo is equipped with large-caliber high-power speakers, otherwise the entire hall will echo Will prevent you from hearing clearly.

　　The correct way is to use a line array column with low total power and high sound pressure level, so that the sound can be transmitted far away, and then assisted by a ceiling speaker to complete the entire sound field under the precise control of each and every speaker in the media matrix Clear and even amplification.

　　2. Use howling feedback suppressor to ensure that the venue's sound reinforcement does not howl.

　　However, for the same reason as the second point, and the position of the user's microphone changes from time to time, *** adopts a frequency-shifting howling feedback suppressor for the audio of the conference speech. In order to avoid the effect of frequency shift on music, you can connect the conference microphone group to the frequency-shifting howling feedback suppressor and then mix it into the main channel, or connect the frequency-shifting howling feedback suppressor to the analog audio output of the digital conference. Enter the mixer or media matrix.

　　3. No general unit has a professionally trained tuner, and audio processing cannot be set too frequently.

　　Otherwise, the hard-tuned sound field effect will be almost unrecognizable in a few months, *** use a smarter processor or even an audio media matrix to process all channels of audio, and apply various applications such as conferences, performances, musical instruments, movie theaters Combined with full environmental parameters, full dissatisfaction, half staff, etc. into a variety of applications pre-stored, through the scene call (*** connected to the centralized control system) to solve the tuning problem, to avoid excessive adjustment by the user.
