不管哪一种广播音响系统，基本可分四个部分：节目源设备、信号放大处理设备、传输线路和扬声器系统。下面
山东公共广播音响厂家为您解说。
No matter what kind of broadcast sound system, it can be basically divided into four parts: program source equipment, signal amplification and processing equipment, transmission line and loudspeaker system. Next, Shandong public broadcasting audio manufacturer will explain it to you.
节目源设备
Program source equipment
通常为传统的如：数字调谐器、多媒体播放机等等；智能的如：数字节目控制中心、校园广播播放机、数字音源播控机、数控惭笔3播放机、滨笔数字广播的如：滨笔网络数字服务器软件等等，他们都是内置数字音源，并且可以对相关系统进行控制的设备。另外还有一些如无线电广播，激光唱机和录音卡座等设备，此外还有传声器、电子乐器等。
Usually traditional, such as digital tuner, multimedia player, etc; Intelligent devices, such as digital program control center, campus broadcast player, digital audio source broadcast controller, digital MP3 player, IP digital broadcasting, such as IP network digital server software, are all built-in digital audio sources and can control related systems. In addition, there are some equipment such as radio broadcasting, CD player and recording cassette stand, as well as microphones, electronic instruments, etc.
信号放大处理设备
Signal amplification and processing equipment
包括均衡器、前置放大器、功率放大器和各种控制器材及音响加工设备等。这部分设备的首要任务是信号放大，其次是信号的选择。
Including equalizer, preamplifier, power amplifier, various control equipment and audio processing equipment. The primary task of this part of equipment is signal amplification, followed by signal selection.
调音台和前置放大器作用和地位相似（当然调音台的功能和性能指标更高），它们的基本功能都是完成信号的选择和前置放大，此外还对音量和音响效果进行各种调整和控制。
The mixer and preamplifier have similar functions and positions (of course, the function and performance indicators of the mixer are higher). Their basic functions are to complete signal selection and preamplification. In addition, they also adjust and control the volume and sound effects.
有时为了更好地进行频率均衡和音色美化，还另外单独投入图示均衡器。这部分是整个广播音响系统的&濒诲辩耻辞;控制中心&谤诲辩耻辞;。
Sometimes, in order to better perform frequency equalization and timbre beautification, graphic equalizer is also used separately. This part is the "control center" of the entire broadcast audio system.
功率放大器则将前置放大器或调音台送来的信号进行功率放大，再通过传输线去推动扬声器放声。
The power amplifier amplifies the signal from the preamplifier or mixer, and then pushes the loudspeaker through the transmission line.\
公共广播智能化要求系统能定时音源，电源，分区，与消防广播联动，因此还有如定时器，节目定时播放器，电源时序器，音频矩阵，控制主机，消防采集器等。
The public address intellectualization requires that the system can time the sound source, power supply, partition, and linkage with the fire broadcast, so there are also timers, program timing players, power sequencers, audio matrices, central control host, fire collectors, etc.
传输线路
Transmission line
虽然简单，但随着系统和传输方式的不同而有不同的要求，一般分为四种，如模拟音频线路、数字双绞线线路、流媒体（滨笔）数据网络线路、数控光纤线路。
Although simple, there are different requirements with different systems and transmission modes, which are generally divided into four types, such as analog audio lines, digital twisted pair lines, streaming media (IP) data network lines, and digital optical fiber lines.
扬声器
speaker
要求整个系统的匹配，同时其位置的选择也要切合实际，室内一般用天花喇叭、室内音柱、壁挂音箱或悬挂式音箱即可，室外可采用室外音柱、草坪专用音箱、号角等等。
The matching of the whole system is required, and the selection of its location should also be practical. Ceiling speakers, indoor sound poles, wall mounted speakers or hanging speakers can be used indoors, while outdoor sound poles, lawn dedicated speakers, horns, etc. can be used outdoors.
