The multi-function lecture hall has many functions, and it is common to use the multi-function conference and lecture as meetings.

 

 

 

Generally speaking, the multi-functional lecture hall covers an area of about 300 square meters to 500 square meters, with a capacity of about 200 to 300 people.

 

 

 

Multifunctional lecture hall for sound field design is more stringent, both before, during and after the venue sound pressure, and the audio quality also requires very high.

 

 

 

The function of the multi-functional lecture hall is mainly to meet the needs of voice amplification, academic reports, learning and training, speech and other functions of daily meetings.

 

 

 

How to Configure the Audio in the Multifunctional Reporting Hall

 

 

 

Through the analysis of the layout environment of the conference room, reasonable arrangement and connection of the audio equipment and installation of the above audio equipment can make the sound source and the end of the audio system - the speaker in the same sound field area, so that the audience can feel the real existence of the sound source, and achieve the requirements of high fidelity and reproduction of sound amplification.

 

 

 

Multifunctional conference room audio is mainly natural sound, which requires good diffusion, uniform distribution of sound field, appropriate loudness and good naturalness.

 

 

 

1. Guarantee a uniform and reasonable sound pressure level.

 

 

 

2. Ensure clarity.

 

 

 

3. Ensure that the system can work steadily.

 

 

 

4. It should have good transmission frequency characteristics and low distortion.

 

 

 

According to the area requirement of the report hall, in order to achieve good sound reinforcement effect of the report hall, the following installation combinations can be adopted.

 

 

 

1. Group speaker.

 

 

 

2. Group wall-mounted speakers.

 

 

 

3. Suction top speaker.

 

 

 

Installation requirements need to be uniformly installed in the front, middle and back of the conference room (in which a group of speakers in the front are monitored by the chair), and a group of suction top speakers are arranged in the middle of the top of the conference room for close sound reinforcement. Achieves the sound reinforcement area to be broad, the sound is clear and bright, is not easy to produce the self-excitation.

 

 

 

The audience has the right loudness. Good naturalness of sound, i. e. sound-image consistency, real reproduction of sound signals. To enable participants to feel the real existence of sound sources, to achieve high-fidelity reproduction of sound amplification requirements. It also meets the requirements of natural sound, good diffusion, uniform distribution of sound field, appropriate loudness and good naturalness.

 

 

 

A complete conference system consists mainly of sound source equipment, such as voice source equipment.

 

 

 

1. Microphone.

 

 

 

2. Mixer.

 

 

 

3. Power amplifier.

 

 

 

4. Speaker.

 

 

 

5. Equalizer.

 

 

 

6. Frequency divider.

 

 

 

Through the above overall configuration, it can basically meet the requirements of multi-functional auditorium for audio.
