I. conference system design
Meeting system functional requirements
The project is a multi-media conference sound amplification system. The project mainly consists of a small conference hall with an area of 40 square meters and a small round table meeting room that can hold 20 people.In this project, the multimedia conference room is mainly required to meet the requirements of daily conference voice amplification, academic reports, learning and training and other functions.The plan, perspective and facade renderings of the conference room are shown below:

2 meeting function design
According to the requirements of the project, in order to achieve good sound amplification effect of the meeting room, it is recommended to use 2 sets of speakers, which are respectively installed in the four corners of the meeting room for sound amplification at close range.To enlarge sound, sound clear and bright, not easy to generate self - excitation.The audience has a suitable loudness.Good sound naturalness, that is, sound and image consistency, sound signal real replay.So that the participants can feel the real existence of the sound source, to achieve the high fidelity playback amplification requirements.And to achieve the multimedia conference room sound to the main natural sound, good diffusion, sound field distribution uniformity, loudness appropriate, good naturalness and other requirements.
Ii. Function of conference system equipment
A complete conference system is mainly composed of sound source equipment (such as microphone, etc.), control equipment (such as mixer, etc.), amplifier equipment (such as power amplifier), playback equipment (such as speakers) and peripheral equipment (such as equalizer, distributor, etc.).
1. Function introduction of main products of the conference system
Microphones: this system USES Settune scs-760c /D chairman/guest mic.Single pointing capacitor microphone;Gooseneck microphone with red speech indicator halo;Microphone status indicator;The red light indicates that the speaker is speaking.The chairman has the priority to speak on behalf of the health, can be closed by banning the health of the speaker unit.
(2) mixer: in this system we use st-mc08u mixer, which is low noise 8 channel built-in 16 digital effects stereo mixer, with 8 single microphone and line balance input, built-in 16 DSP digital delay effect.
(3) equalizer: this program we use st-eq602 equalizer, which is 31 stereo graphic equalizer, with FBQ feedback detection system can display feedback audio and frequency analysis.
(4) power amplifier: according to the actual situation and functional requirements of this project, we used the st-pm-300 professional conference amplifier matched with the speaker in the conference sound amplification system. The amplifier produced by this company has the characteristics of good quality and high stability, and its products have superior quality and extraordinary performance.This amplifier is a smart choice for multimedia conference engineering.
(5) speaker: in this conference room project, we use st-es200 professional conference speaker, ES series professional conference speaker high sensitivity, speaker design are using low impedance, effectively reduce the internal resistance loss, effectively improve the sound reduction characteristics.It can effectively reduce the feedback noise caused by sound field and improve the clarity of sound.
6 power sequencer: this project we use st-p382 power sequencer, which has the characteristics of automatic according to the set time switch sequencer, so that engineers can switch the whole audio system with a switch.And it can automatically and timely monitor the power supply voltage and system working current, when the danger level is reached, an alarm will be issued.
The conference system is mainly composed of sound source equipment, control equipment, amplification equipment and playback equipment.In the meeting system, the st-mc08u mixer is connected to the Settune scs-760 hand-holding system control host and the st-eq602 equalizer respectively.The equalizer is connected to the st-pm300 power amplifier;The amplifier connects to the st-es200 professional conference speaker.-
