會議音響
Conference sound
會議音響系統，則主要應用于會議培訓講座等的擴聲。會議音響主要考慮采用會議專用擴聲系統(注：如手拉手會議)或常規擴聲系統，配置相應的會議話筒等。
Conference sound system is mainly used for sound reinforcement of conference training lectures, etc. The conference sound system mainly considers the use of special conference sound reinforcement system (Note: such as hand-in-hand Conference) or conventional sound reinforcement system, equipped with corresponding conference microphone, etc.
會議音響普通配置通常是調音臺功放和一對音箱，中高檔配置可選配周邊設備或音頻綜合處理器及反饋抑制器等，具體場景系統指標視使用檔次及預算投入。
The general configuration of conference audio is usually mixer power amplifier and a pair of speakers. For medium and high-grade configuration, peripheral equipment or audio integrated processor and feedback suppressor can be selected. The specific scene system indicators depend on the use level and budget investment.
公共廣播音響
Public address sound
公共廣播音響系統，一般是應用在大型建筑中，如機場火車站展覽中心綜合辦公區等，用于播放背景音樂廣播通知等。公共廣播音響一般注重考慮語言或背景音樂，在音箱或喇叭的布置方面，考慮聲音覆蓋的均勻度。
Public broadcasting sound system is generally used in large buildings, such as shopping malls, airports, railway stations, exhibition centers, comprehensive office areas, etc., for playing background music, broadcasting notices, etc. Public broadcasting sound generally focuses on language or background music, and the uniformity of sound coverage is considered in the layout of speakers or speakers.
公共廣播音響配置簡單明了，除信號源之外，加上簡單的程序控制功能及相應的定壓或功放等，程式相對固定，頻響在100~10KHz之間。
The public address sound configuration is simple and clear. In addition to the signal source, with simple program control function and corresponding constant voltage or power amplifier, the program is relatively fixed and the frequency response is between 100 ~ 10kHz.
舞臺演出音響
Stage performance sound
舞臺演出音響系統，主要應用于演出擴聲。可以分為室內舞臺演出與室外舞臺演出，不同場合要求有所不同。舞臺音響主要針對不同演出，如戲曲演唱會音樂會話劇等，突出特點進行系統配置布置。
Stage performance sound system is mainly used for performance sound reinforcement. It can be divided into indoor stage performance and outdoor stage performance, with different requirements on different occasions. The stage sound system is mainly configured and arranged for different performances, such as opera concerts, concerts, dramas, etc.
演出舞臺音響配置要求應該是高的，系統組成較為復雜、靈活。比如均衡、延時、壓限、分頻、混響、激勵等周邊設備，要求具有較寬頻響范圍，通常在35~20KHz之間，輸出功率在幾千瓦乃上萬瓦，音箱在十幾只到幾十只，所有設備工作狀態要求均處于高保真模式中。
The requirements for the sound configuration of the performance stage should be high, and the system composition is more complex and flexible. For example, peripheral equipment such as equalization, time delay, voltage limit, frequency division, reverberation and excitation are required to have a wide frequency response range, usually between 35 ~ 20kHz, output power of thousands of watts or even tens of thousands of watts, speakers of more than ten to dozens, and all equipment are required to be in high fidelity mode.
