公共广播以及组成原理概述纲要2008/11/17/15:24 慧聪音响灯光网公共广播系统（Public Address System简称PA），这种是有线广播系统，它包括背景音乐和紧急广播功能，通常结合在一起，平时播放背景音乐或其他节目，出现火灾等紧急事故时，转换为报警广播。
广播用的话筒与向公众广播的扬声器一般不处同一房间内，所以没有声反馈的问题，以定压式传输方式为其典型系统。
演出护声系统，这种系统使用专业音响设备，并要求有大功率的扬声器系统和功放，由于传声器与扩声用的扬声器同处于一个厅堂内，故存在声反馈乃至啸叫的问题，且因其距离较短，所以系统一般采用低阻直接传输方式；专用的会议系统，它虽也属扩声系统，但有其特殊要求，如同声传译系统等。
注：讲述公共广播系统与其他类的广播系统的区别，如家庭用的的HI-FI音响系统，影院的音响系统等等。
它们输出是定阻式，公共广播是定压式广播系统，输出先将要传输的音源信号升压后，然后在终端（放音设备如：喇叭——经变压器降压，再到喇叭放出声音，之所以用升压降目的是为了能够将声音远距离传输，高电压传输损耗小，距离远。
公共广播主要是应用于远距离广播以及背景音乐，它是单声道系统，不考虑立体声，主要应用于公共场合，居民区，学校、宾馆酒店，园林，大型超市，大型广场，。
主要目的是广播以及背景音乐，给周围环境创造一种轻松的氛围，给人心情舒畅，抑制环境噪声，另外，在一些学校等教育部门，公共广播还可以进行学校的教学活动，如：日常广播，课间操，学校广场通知等等一、广播音响系统的组成广播音响系统基本可分四个部分：节目设备、信号的放大和处理设备、传输线路和扬声器系统。
音源设备：通常为CD机和录音卡座等，此外还有传声器（如话筒，电子乐器）。
信号放大和处理设备：包括调音台、前置放大器、功率放大器和各种控制器及音响加工设备等。
这部分设备的首要任务是信号放大，其次是信号的选择。
传输线路：传输线路虽然简单，但随着系统和传输方式的不同而有不同的要求。

1 公共广播系统1.1 系统概述公共建筑的背景音响与应急广播系统（公共广播系统）功能一般可分为业务性广播、服务性广播和火灾事故广播三种，服务性广播又包括背景音乐广播。
它是公共建筑的基础支持系统，主要用于突发情况的紧急广播，如消防紧急广播的播出；其次用于服务性广播掩盖环境噪声并营造舒适的环境气氛，以及业务广播通知、呼叫播音等信息播出；再次，随着技术发展及产品功能完善，能够实现区域内本地音源节目的现场接入播出。
大型体育场馆的公共广播系统应用以火灾应急广播功能为主，兼备背景音乐及业务广播、竞赛信息广播等功能，并可以根据所采用的组网方式和设备灵活设置辅助功能，分区能够灵活设置并选择不同音源播出，最大程度的发挥公共广播系统在体育场里的作用。
1.2 需求分析根据招标要求及本项目的结构特点，同时考虑公共广播对扩声要求的特殊性，除以上功能区域分析、基本需求分析外，我们也充分考虑并提供给用户如下特色功能：分区灵活——由于拥有多个功能区域，系统可以对背景音乐分区进行灵活的组合以适应不同区域的需要；多音乐输出——背景音乐系统在必要情况下，要能为不同的功能区提供不同的背景音乐；针对以上特色功能，并充分发挥我们对于智能广播系统的技术集成优势，在充分满足当前需求的前提下，为将来的系统扩容预留足够的空间，提出了如下设计构想：在xx区体育中心设立一个广播系统总控机房，用于对整个广播系统的控制和管理，总控机房配备一套前端音源、总控呼叫站、系统控制主机（主机）和供给整个建筑扬声器的功率放大器；在消防控制室/消防中央控制室设立广播系统分控呼叫站。
分控呼叫站与总控呼叫站具有相同的功能。
分控呼叫站通过RJ45线缆传输，最长有效距离为1000米。
广播总控机房的功能主要有：➢能够对所有广播进行控制管理；➢能够对所有分区的扬声器进行音量调整和音源监听；➢系统监测，所有主机设备的故障信息能够即时反馈在系统主机和控制计算机上，便于及时排除故障；➢线路监测，能够对本系统内的线路进行监测（包括断路、短路和接地）并反馈给系统主机和控制计算机。

一、 简易的校园广播系统最简易的系统如图一。
LD 系列广播扬声器LD 系列广播扬声器广播功放、广播线路和广播扬声器与普通家用的或HiFi 的专业功放、音箱线、扬声器不尽相同。
由于广播线路通常相当长（几十米乃至上千米），为减少传输损耗，广播信号原则上是用高电压 / 小电流的方式传输。
所以广播功放须提供高压信号，因此广播功放都内置有输出变压器用以提升广播信号电压；同时，为了便于配接广播扬声器，广播功放应是定压输出模式，其输出端子标示70V / 100V / 120V 等规格。
另外，300W 以下常规的小功率广播功放通常自带前置级（典型的如OTEW A-TA22/33系列），属合并式功放。
由于系统用高压传输，所以广播线路一般不必使用昂贵的HiFi 音箱线而只须用普通的双绞线；如果配置在室外，则应加防雷设施（见下文）。
相应地，广播扬声器原则上应是高阻扬声器，它们都有内置的“线间变压器” （阻抗变换 / 降压用），其输入端子也标示70V/100V/120V 等适用电压规格。
广播扬声器同广播功放之间的匹配规则非常简单：首先，广播扬声器的输入标称电压原则上应同广播功放的输出标称电压相同；在这样的前提下，只要所有广播扬声器的总功率不大于广播功放的额定输出功率即可（这是理论值，有关规程另有限定，见下文）。
公共广播系统方案排版介绍公共广播系统是一种集语音、音乐等多种功能于一体的信息发布系统。
它被广泛应用于学校、办公楼、商场、医院等各类公共场所，用于为人们提供实时信息、紧急通知以及背景音乐等服务。
本文将详细探讨公共广播系统的方案排版，包括系统需求、布局设计、音频设备选择等方面内容。
系统需求区域划分公共场所通常分为不同的区域，例如会议室、走廊、办公区等。
广播系统需要能够独立控制不同区域的音量、音乐选择等功能。
因此，在方案排版时需要根据实际情况将场所划分为不同的区域，并为每个区域分配相应的音频设备。
紧急通知在紧急情况下，例如火警、自然灾害等，公共广播系统需要能够迅速发布通知，以便及时疏散人员。
因此，在方案排版时需要考虑并配备紧急通知装置，以确保紧急通知的及时性和可靠性。
音质要求公共广播系统的音质直接关系到用户体验，因此在方案排版时，需要注意选择高质量的音频设备，并合理设计扬声器的布局，以保证音质的清晰、均衡。
系统可扩展性公共场所的布局可能存在变动，例如会议室合并、普通办公区调整等。
因此，在方案排版时，需要考虑系统的可扩展性，即能够根据实际情况方便地增减音频设备或重新布局。
布局设计案例分析：学校公共广播系统以学校为例，公共广播系统的方案排版应考虑以下几个因素：1.学校布局：学校通常由教学楼、图书馆、食堂、操场等区域组成。
在方案排版时，应根据不同区域的特点和使用频率，合理划分较小的区域。
2.主控室位置选择：主控室的位置应该尽量靠近各个区域，以减小音频线路的传输损耗，确保信号的稳定性。
3.扬声器布局：扬声器应根据各个区域的布局和面积合理摆放，并考虑声音的覆盖范围和反射情况。
在教室等环境中，扬声器应尽量避免反射产生的回音。
4.音频设备选择：根据场地的大小和环境的噪音情况，选择合适的音频设备，例如功率放大器、混音器、音源接口等。
方案排版示意图下图为一个学校公共广播系统的方案排版示意图：音频设备选择公共广播系统的音频设备选择应考虑以下几个因素：1.功率放大器：选择功率适中的放大器，使音频信号在传输过程中不会因为功率不足而导致信噪比下降。
