山東公共廣播音響根據傳輸方式和信號處理方式的不同，公共廣播系統可分為以下幾類(lèi):傳統的方法模擬功率信號通過(guò)音頻線(xiàn)路傳輸到終端揚聲器，而房間里的功放則用高電平傳輸到揚聲器，一般為100V或70V，其優(yōu)點(diǎn)是線(xiàn)路損耗少，負載連接方便，只需揚聲器用降壓變壓器和線(xiàn)路連接即可。
According to the different transmission methods and signal processing methods, Shandong public address systems can be divided into the following categories: the traditional method is to transmit analog power signals to the terminal speakers through audio lines, while the power amplifiers in the room are transmitted to the speakers with high levels, generally 100V or 70V. Its advantages are that the line loss is small, and the load connection is convenient. Only the speakers are connected with step-down transformers and lines.
數控方式意義上的數字可尋址公共廣播音響信息系統通過(guò)音頻信號、控制相關(guān)信號和通信技術(shù)都是在數字域內進(jìn)行的，具有時(shí)間較長(cháng)的傳輸距離和較好的傳輸教學(xué)效果，特別是音頻信號和控制以及信號主要集中在雙絞線(xiàn)傳輸中。
Digital addressable public address audio information system in the sense of numerical control is carried out in the digital domain through audio signal, control related signal and communication technology, which has a long transmission distance and good transmission teaching effect, especially audio signal, control and signal are mainly concentrated in twisted pair transmission.
IP網(wǎng)絡(luò )廣播是基于網(wǎng)絡(luò )的純數字音頻廣播系統，不同于傳統的模擬音頻、FM、尋址和無(wú)線(xiàn)電廣播信息系統，流媒體(IP)智能發(fā)展數字廣播管理系統能夠完全兼容，無(wú)需額外布線(xiàn)，可以有效使用企業(yè)現有的校園網(wǎng)或內部網(wǎng);嵌入式硬件終端。
IP network broadcasting is a purely digital audio broadcasting system based on the network. Different from the traditional analog audio, FM, addressing and radio broadcasting information systems in China, the streaming media (IP) intelligent development digital broadcasting management system can be fully compatible, without additional wiring, and can effectively use the existing campus network or intranet of enterprises; Embedded hardware terminal.
可以根據設置一個(gè)獨立的IP地址，通過(guò)多層交換機，通過(guò)主機之間可以發(fā)現任意控制各終端的設置和播放，還可以在終端上選擇自己所需的節目研究?jì)热荨?/div>
You can set an independent IP address according to the settings. Through the multi-layer switch, you can find the settings and playback of each terminal arbitrarily controlled through the hosts. You can also select the program research content you need on the terminals.
由于采用了計算機科學(xué)技術(shù)，本系統幾乎我們可以兼容所有的音頻數據格式，采用了IP技術(shù)，廣播電視節目主要內容方面可以不受任何限制，每個(gè)終端都可以自由播放一些需要的節目服務(wù)內容。
Due to the adoption of computer science and technology, this system can be compatible with almost all audio data formats. With the adoption of IP technology, the main content of radio and television programs can be free from any national restrictions, and each terminal can freely broadcast some required program service content.
它可以進(jìn)行完全取代傳統的基于模擬或數字的智能廣播系統，能夠實(shí)現企業(yè)基于我國互聯(lián)網(wǎng)或局域網(wǎng)的IP音頻廣播功能。它支持直播、直播、點(diǎn)播等方式。一些產(chǎn)品支持全雙工雙向對講、終端語(yǔ)音等功能，支持廣泛的流行應用。
It can completely replace the traditional analog or digital based intelligent broadcasting system in China, and can realize the IP audio broadcasting function of enterprises based on China's Internet or LAN. It supports live broadcast, live broadcast, on-demand and other methods. Some products support full duplex two-way intercom, terminal voice and other functions, and support a wide range of popular applications.
公共廣播音響系統可按其功能和使用性質(zhì)分為以下幾類(lèi):這是一個(gè)基于商業(yè)和行政管理的語(yǔ)言廣播。適用于寫(xiě)字樓、商業(yè)大廈、事業(yè)單位、大專(zhuān)院校、車(chē)站、碼頭、機場(chǎng)等場(chǎng)所。商業(yè)廣播通常由主管部門(mén)管理。
Public address sound system can be divided into the following categories according to its function and use nature: it is a language broadcast based on business and administration. It is applicable to office buildings, commercial buildings, institutions, colleges and universities, stations, docks, airports and other places. Commercial broadcasting is usually managed by competent authorities.
服務(wù)，這是作為一種以享受背景音樂(lè )教育為主的具有服務(wù)工作性質(zhì)的廣播系統，常用于酒店、酒店、銀行、證券、公園、廣場(chǎng)和大型企業(yè)公共管理活動(dòng)等場(chǎng)所;緊急，公共廣播音響系統是為滿(mǎn)足火災等緊急事件中指導人員疏散的要求而設計的。通常，此廣播系統與前兩種系統結合使用。在進(jìn)行系統組合設計時(shí)，應根據應急廣播系統的要求確定系統。
Service, which is a broadcasting system with the nature of service and work, mainly for enjoying background music education, and is often used in hotels, hotels, banks, securities, parks, squares and public management activities of large enterprises; Emergency, public address sound system is designed to meet the requirements of guiding personnel evacuation in fire and other emergencies. Generally, this broadcasting system is used in combination with the first two systems. During system combination design, the system shall be determined according to the requirements of emergency broadcasting system.
此外公共廣播音響系統隸屬于擴聲音響系統類(lèi)目中，好的公共廣播音響系統解決方案涉及合理，正確的電聲系統設計和調試，良好的聲音傳播環(huán)境(建聲條件)和精確的現場(chǎng)調音三者佳的結合，三者相輔相成缺一不可。更多相關(guān)內容的了解就來(lái)我們網(wǎng)站

In addition, the public address sound system belongs to the category of sound reinforcement systems. A good public address sound system solution involves reasonable, correct design and debugging of the electroacoustic system, a good sound transmission environment (building sound conditions) and accurate on-site tuning, which complement each other.
