山東公共廣播音響根據(jù)傳輸方式和信號(hào)處理方式的不同，公共廣播系統(tǒng)可分為以下幾類:傳統(tǒng)的方法模擬功率信號(hào)通過音頻線路傳輸?shù)浇K端揚(yáng)聲器，而房間里的功放則用高電平傳輸?shù)綋P(yáng)聲器，一般為100V或70V，其優(yōu)點(diǎn)是線路損耗少，負(fù)載連接方便，只需揚(yáng)聲器用降壓變壓器和線路連接即可。
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(shù)控方式意義上的數(shù)字可尋址公共廣播音響信息系統(tǒng)通過音頻信號(hào)、控制相關(guān)信號(hào)和通信技術(shù)都是在數(shù)字域內(nèi)進(jìn)行的，具有時(shí)間較長(zhǎng)的傳輸距離和較好的傳輸教學(xué)效果，特別是音頻信號(hào)和控制以及信號(hào)主要集中在雙絞線傳輸中。
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(shù)字音頻廣播系統(tǒng)，不同于傳統(tǒng)的模擬音頻、FM、尋址和無線電廣播信息系統(tǒng)，流媒體(IP)智能發(fā)展數(shù)字廣播管理系統(tǒng)能夠完全兼容，無需額外布線，可以有效使用企業(yè)現(xiàn)有的校園網(wǎng)或內(nèi)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(jù)設(shè)置一個(gè)獨(dú)立的IP地址，通過多層交換機(jī)，通過主機(jī)之間可以發(fā)現(xiàn)任意控制各終端的設(shè)置和播放，還可以在終端上選擇自己所需的節(jié)目研究?jī)?nèi)容。
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(jì)算機(jī)科學(xué)技術(shù)，本系統(tǒng)幾乎我們可以兼容所有的音頻數(shù)據(jù)格式，采用了IP技術(shù)，廣播電視節(jié)目主要內(nèi)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(jié)目服務(wù)內(nèi)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(tǒng)的基于模擬或數(shù)字的智能廣播系統(tǒng)，能夠?qū)崿F(xiàn)企業(yè)基于我國(guó)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?qū)χv、終端語音等功能，支持廣泛的流行應(yīng)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(tǒng)可按其功能和使用性質(zhì)分為以下幾類:這是一個(gè)基于商業(yè)和行政管理的語言廣播。適用于寫字樓、商業(yè)大廈、事業(yè)單位、大專院校、車站、碼頭、機(jī)場(chǎng)等場(chǎng)所。商業(yè)廣播通常由主管部門管理。
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教育為主的具有服務(wù)工作性質(zhì)的廣播系統(tǒng)，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(tǒng)是為滿足火災(zāi)等緊急事件中指導(dǎo)人員疏散的要求而設(shè)計(jì)的。通常，此廣播系統(tǒng)與前兩種系統(tǒng)結(jié)合使用。在進(jìn)行系統(tǒng)組合設(shè)計(jì)時(shí)，應(yīng)根據(jù)應(yīng)急廣播系統(tǒng)的要求確定系統(tǒng)。
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(tǒng)隸屬于擴(kuò)聲音響系統(tǒng)類目中，好的公共廣播音響系統(tǒng)解決方案涉及合理，正確的電聲系統(tǒng)設(shè)計(jì)和調(diào)試，良好的聲音傳播環(huán)境(建聲條件)和精確的現(xiàn)場(chǎng)調(diào)音三者佳的結(jié)合，三者相輔相成缺一不可。更多相關(guān)內(nèi)容的了解就來我們網(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.
