The sound reinforcement system of the conference venue is divided into two types, one is the multi-function hall sound reinforcement system, and the other is the conference sound reinforcement system. In addition to meetings, reports and other activities, the multi-functional conference room is also a place for employees to engage in recreational activities, such as performing dance performances such as song and dance, music, drama, etc., and requires high-quality sound reinforcement systems to cooperate with them. The sound source is restored as perfectly as possible to ensure the smooth progress of various performances, so that the actors and the audience can enjoy the beauty of the music and enjoy the beauty of the art, in addition to the visual beauty. The sound reinforcement system designed has a higher and more uniform sound field design, and has better sound signal clarity and fullness.
Main speakers, subwoofers, returning speakers, auxiliary speakers, fill speakers, and audio speakers are usually added according to the size of the venue plus audio processing equipment, power amplifiers, and tuning equipment. Comes with several wireless handheld and lavalier microphones. Here, Ruiqun Technology puts three points to note:
1. This kind of place is not a professional performance hall. There is no sound design on the building. It can only be used as soft decoration as possible to obtain a better sound field, so that the electroacoustic meets the requirements. But some there is no soft decoration, such as the court's trial hall, almost the national courtroom is small in the 200-300 square meters, the large nearly thousand square meters, there are 5-7 meters high, in order to reflect the solemnity, the decoration used They are all hard materials, and they are square and all face to face. The ground is terrazzo or wooden floor. The walls are all made of hard wood. This kind of sound reinforcement is equipped with large-caliber high-power speakers, otherwise the whole hall echoes. You will not be able to hear the speech. The correct way is to use a line array sound column with low total power and high sound pressure level, so that the sound can be transmitted far away, and then assist the ceiling speaker to complete the whole sound field under the precise control of each matrix and each speaker in the media matrix. Clear and uniform amplification.
Second, use the howling feedback suppressor to ensure that the venue does not scream. However, for the same reason as the second point, and the position of the user's microphone changes from time to time, it is better to use a frequency-shifting howling feedback suppressor for the conference speech audio (the group system of Ruiqun contains this technology). In order to avoid the influence of frequency shift on music, the conference microphone group can be connected to the frequency shifting howling feedback suppressor, and then mixed into the main channel, or the digital conference analog audio output can be connected to the frequency shifting howling feedback suppressor. Go to the mixer or media matrix.
Third, the general unit has no professionally trained tuner, audio processing can not be set too often, otherwise the sound field effect that has been painstakingly transferred, almost unrecognizable after a few months, it is best to use a smarter processor or even audio The media matrix processes each channel of audio, and combines various applications such as conferences, performances, musical instruments, movies, and environmental parameters in full, dissatisfied, half-person, etc. into various applications for pre-storage, through scene calls (best and concentrated The control system is connected to solve the tuning problem and avoid excessive adjustment by the user.
Pure hand in hand to discuss the system sound reinforcement, generally requires clear, bright, high intelligibility, background music melodious. Therefore, it is generally used to sound column, wall-mounted speaker, ceiling speaker, etc. with moderate power and high sound pressure, and frequency shifting whistling feedback suppressor is often used in audio processing.
