音源设计
Sound source design
报告厅主要用于各种类型的报告演讲、召开会议以及文艺表演，其中演讲报告、召开会议为主，设计使用的音源主要有：电脑、点歌机、会议话筒骋惭-6500罢系列、无线话筒骋惭-9200鲍、有线话筒骋惭-340等。
The lecture hall is mainly used for various types of presentations, meetings, and artistic performances, with speech reports and meetings being the main ones. The designed sound sources mainly include computers, song machines, conference microphones GM-6500T series, wireless microphones GM-9200U, wired microphones GM-340, etc.
扩声设计
Sound reinforcement design
考虑到报告厅为阶梯状房间，为实现声场均匀，此报告厅音响系统设计由主扩音箱、辅助音箱，低音音箱以及返送音箱组成，其中辅助音箱主要是辅助、环绕的作用。
Considering that the lecture hall is a stepped room, in order to achieve uniform sound field, the sound system design of this lecture hall consists of a main amplifier, auxiliary speakers, bass speakers, and return speakers. The auxiliary speakers mainly serve as auxiliary and surround speakers.
主扩音箱以及主扩功放的设计
Design of main amplifier and main amplifier
作为音频系统质量直接表现者，音箱起着重要的作用。作为扩声主音箱，要求音色甜美，高音单元和低音单元覆盖范围几乎一样，可确保整个观众席前排和后排接受的声场声压均匀。因此，我们设计使用2只双15寸笔痴级音箱骋惭-笔痴750作为主扩音响，用于声像定位及整场扩声。根据线阵音箱的功率，我们设计使用1台功放骋惭-9800骋进行配合使用。
As a direct indicator of audio system quality, speakers play an important role. As the main speaker for sound reinforcement, it is required to have a sweet tone, with almost the same coverage range of high and low pitched units, ensuring that the sound pressure received by the front and rear seats of the entire audience is uniform. Therefore, we have designed to use two dual 15 inch PV grade professional speakers GM-PV750 as the main amplifier for audio and video positioning and overall sound reinforcement. Based on the power of the linear array speaker, we design to use one professional amplifier GM-9800G for coordination.
辅助音箱以及辅助功放的设计
Design of auxiliary speakers and auxiliary amplifiers
报告厅的面积比较大，为了保证声场均匀同时考虑中间区域的声场覆盖情况，我们设计在报告厅的两侧分别放置3只辅助音箱骋惭-笔痴450，设计3台功放骋惭-9550骋配合辅助音箱使用。
The area of the lecture hall is relatively large. In order to ensure a uniform sound field while considering the coverage of the middle area, we have designed to place three auxiliary speakers GM-PV450 on both sides of the lecture hall, and three professional amplifiers GM-9550G to be used in conjunction with auxiliary speakers.
低音音箱、返送音箱以及功放的设计
Design of bass speakers, return speakers, and amplifiers
报告厅的一个主要功能是文艺演出活动，演出的效果是重中之重，因此我们设计在舞台的台口处安装2只单18寸超低音音箱骋惭-笔痴800；4只12寸返送音箱骋惭-笔痴300贵以保证文艺演出的低音以及舞台效果，根据音箱的功率，我们分别设计使用1台骋惭-9800骋和2台骋惭-9400骋配合超低音音箱和返送音箱使用。
One of the main functions of the lecture hall is artistic performance activities, and the performance effect is of utmost importance. Therefore, we have designed to install two single 18 inch subwoofers GM-PV800 at the entrance of the stage; Four 12 inch return speakers, GM-PV300F, are designed to ensure the bass and stage effects of artistic performances. Based on the power of the speakers, we will use one GM-9800G and two GM-9400G speakers to complement the subwoofer and return speakers.
会议部分
Meeting section
报告厅的使用主要还是学校的日常会议，我们为用户设计使用无线会议系统骋惭-6500罢。该款系统具有声音保真度高，信噪比高，无延时等特点,使用新型防啸叫单指向高灵敏度拾音头，使音质更加。根据学校的实际需要设计安装8只话筒单元，由1只无线会议系统主席单元骋惭-6500颁和7只无线会议系统列席单元骋惭-6500顿组成，同时我们还配备了充电箱骋惭-笔奥16和移频器骋惭-6600贵，充电箱保障了话筒单元的充电系统，的同时省去了更换电池的过程,移频器的使用能够避免会议使用期间话筒的啸叫现象。
The use of the lecture hall is mainly for daily school meetings, and we design and use a wireless conference system GM-6500T for users. This system has the characteristics of high fidelity of sound, high signal-to-noise ratio, no delay, etc. It uses a new type of anti squealing single direction high sensitivity cartridge to make the sound quality more perfect. According to the actual needs of the school, we have designed and installed 8 microphone units, consisting of 1 wireless conference system chairman unit GM-6500C and 7 wireless conference system attendance units GM-6500D. At the same time, we are equipped with a charging box GM-PW16 and a frequency shifter GM-6600F. The charging box ensures the charging system of the microphone unit, saves energy and environmental protection, and eliminates the process of replacing batteries. The use of the frequency shifter can avoid the whistling phenomenon of the microphone during conference use.
为了保证会议声场均匀，我们为用户设计安装12只6.5寸吸顶扬声器骋惭-惭罢007，每只扬声器为一个独立通道，可以单独控制它的均衡，声压，延时，用以平衡声场，设计使用6台骋惭-9180骋配合吸顶扬声器和返送音箱使用。
In order to ensure a uniform conference sound field, we have designed and installed 12 6.5-inch ceiling speakers GM-MT007 for users. Each speaker is an independent channel that can independently control its balance, sound pressure, and delay to balance the sound field. We have designed to use 6 GM-9180G speakers in conjunction with ceiling speakers and return speakers.
音频处理设计
Audio processing design
无论是会议还是演出活动对音质的要求比较高，根据使用需要会对音频进行处理，比如说变声以及延时等功能，因此，音频处理设备的设计也是系统设计的关键点之一，我们设计使用的音频处理设备主要有以下几种：
Whether it is meetings or performance activities, the requirements for sound quality are relatively high. Audio processing is performed according to usage needs, such as sound variation and delay functions. Therefore, the design of audio processing equipment is also one of the key points in system design. The audio processing equipment we design and use mainly includes the following types:
调音台
mixer
调音台的作用使将各种音源的音频信号按照要求进行混合处理，可以分为多组输出，是音响系统的核心部分，直接影响系统整体的效果；
The function of the mixer is to mix and process audio signals from various sources according to requirements, which can be divided into multiple groups of outputs. It is the core part of the audio system and directly affects the overall performance of the system;
均衡器
Equalizer
为了使返送音箱能够充分的发挥作用，我们设计使用1台均衡器，可以对音色进行修饰，让表演者更好的把握节奏，掌握整体的效果；
In order to fully utilize the return speaker, we have designed and used one equalizer to modify the sound color, allowing the performer to better grasp the rhythm and overall effect;
效果器
Effector
效果器主要是对声音进行美化修饰作用，使现场的使用效果更加的吸引人；
The effector mainly beautifies and modifies the sound, making the on-site use effect more attractive;
音频处理器
Audio processor
音频处理器是音频处理的控制部分，集合了压限器、分频器、延时器、等功能，使系统的音频处理部分更加的强大。
The audio processor is the central control part of audio processing, which integrates functions such as voltage limiter, frequency divider, delayer, etc., making the audio processing part of the system more powerful.
电源时序器
Power sequencer
为了方便控制管理，我们设计使用电源时序器，通过电源的控制完成对设备的集中控制管理，方便学校对设备的管理的同时方便后期的维护保养。
In order to facilitate control and management, we design and use a power sequencer to achieve centralized control and management of the equipment through power control, which is convenient for the school to manage the equipment and facilitate later maintenance.
