不管哪一種廣播音響系統(tǒng)，基本可分四個(gè)部分：節(jié)目源設(shè)備、信號(hào)放大處理設(shè)備、傳輸線路和揚(yáng)聲器系統(tǒng)。下面
山東公共廣播音響廠家為您解說(shuō)。
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.
節(jié)目源設(shè)備
Program source equipment
通常為傳統(tǒng)的如：數(shù)字調(diào)諧器、多媒體播放機(jī)等等；智能的如：數(shù)字節(jié)目控制中心、校園廣播播放機(jī)、數(shù)字音源播控機(jī)、數(shù)控MP3播放機(jī)、IP數(shù)字廣播的如：IP網(wǎng)絡(luò)數(shù)字服務(wù)器軟件等等，他們都是內(nèi)置數(shù)字音源，并且可以對(duì)相關(guān)系統(tǒng)進(jìn)行控制的設(shè)備。另外還有一些如無(wú)線電廣播，激光唱機(jī)和錄音卡座等設(shè)備，此外還有傳聲器、電子樂(lè)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.
信號(hào)放大處理設(shè)備
Signal amplification and processing equipment
包括均衡器、前置放大器、功率放大器和各種控制器材及音響加工設(shè)備等。這部分設(shè)備的首要任務(wù)是信號(hào)放大，其次是信號(hào)的選擇。
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.
調(diào)音臺(tái)和前置放大器作用和地位相似（當(dāng)然調(diào)音臺(tái)的功能和性能指標(biāo)更高），它們的基本功能都是完成信號(hào)的選擇和前置放大，此外還對(duì)音量和音響效果進(jìn)行各種調(diào)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.
有時(shí)為了更好地進(jìn)行頻率均衡和音色美化，還另外單獨(dú)投入圖示均衡器。這部分是整個(gè)廣播音響系統(tǒng)的“控制中心”。
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.
功率放大器則將前置放大器或調(diào)音臺(tái)送來(lái)的信號(hào)進(jìn)行功率放大，再通過(guò)傳輸線去推動(dòng)揚(yáng)聲器放聲。
The power amplifier amplifies the signal from the preamplifier or mixer, and then pushes the loudspeaker through the transmission line.\
公共廣播智能化要求系統(tǒng)能定時(shí)音源，電源，分區(qū)，與消防廣播聯(lián)動(dòng)，因此還有如定時(shí)器，節(jié)目定時(shí)播放器，電源時(shí)序器，音頻矩陣，控制主機(jī)，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.
傳輸線路
Transmission line
雖然簡(jiǎn)單，但隨著系統(tǒng)和傳輸方式的不同而有不同的要求，一般分為四種，如模擬音頻線路、數(shù)字雙絞線線路、流媒體（IP）數(shù)據(jù)網(wǎng)絡(luò)線路、數(shù)控光纖線路。
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.
揚(yáng)聲器
speaker
要求整個(gè)系統(tǒng)的匹配，同時(shí)其位置的選擇也要切合實(shí)際，室內(nèi)一般用天花喇叭、室內(nèi)音柱、壁掛音箱或懸掛式音箱即可，室外可采用室外音柱、草坪專用音箱、號(hào)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.
