口碑好的舞臺(tái)音響設(shè)備，不僅具備傳播距離遠(yuǎn)和高音穿透力好的特點(diǎn)，并且音色優(yōu)美、音質(zhì)音效突出，能夠?yàn)橛^眾打造一場(chǎng)悅耳動(dòng)聽(tīng)、酣暢淋漓的視聽(tīng)盛宴，那么關(guān)于
舞臺(tái)音響設(shè)備的選型您了解多少呢？
The professional stage audio equipment with good reputation not only has the characteristics of long propagation distance and good penetration of high pitched, but also has beautiful sound quality and outstanding sound effect, which can create a pleasant and enjoyable audio-visual feast for the audience. How much do you know about the selection of stage audio equipment?
音箱
loudspeaker box
音箱是整個(gè)音響系統(tǒng)的喉舌，因而應(yīng)作為首要因素考慮。音箱選型要從音箱的靈敏度和額定功率著手，確定每個(gè)聲源的功率。由音箱的指向性去分析、控制廳堂聲場(chǎng)，確定每一個(gè)音箱位置、輸入阻抗和輸入功率，計(jì)算音箱與功率放大器間的匹配功率。
The speaker is the mouthpiece of the entire audio system, so it should be considered as the primary factor. The speaker selection shall start with the sensitivity and rated power of the speaker to determine the power of each sound source. Analyze and control the sound field of the hall according to the directivity of the speakers, determine the position, input impedance and input power of each speaker, and calculate the matching power between the speaker and the power amplifier.
功率放大器
power amplifier
為了保證擴(kuò)聲系統(tǒng)總的音質(zhì)效果，功率放大器要有足夠的功率余量，并能長(zhǎng)期穩(wěn)定地工作。同時(shí)所選擇的放大器在提率、減小失真、短路與空載保護(hù)、降低溫升等方面，均應(yīng)有完善的技術(shù)措施。
In order to ensure the overall sound quality effect of the sound reinforcement system, the power amplifier should have sufficient power margin and can work stably for a long time. At the same time, the selected amplifier should have perfect technical measures in improving efficiency, reducing distortion, short-circuit and no-load protection, and reducing temperature rise.
調(diào)音臺(tái)與其它設(shè)備
Mixer and other equipment
調(diào)音臺(tái)是整個(gè)音響系統(tǒng)的心臟部分。它應(yīng)有良好的電氣性能，穩(wěn)定的工作狀態(tài)，平直的頻率響應(yīng)，很小的諧波失真，調(diào)音臺(tái)在功能方面差異很大，這就要根據(jù)整個(gè)系統(tǒng)的功能要求去選擇不同數(shù)量的輸入通道和輸出編組的調(diào)音臺(tái)。
The mixer is the heart of the whole audio system. It should have good electrical performance, stable working state, flat frequency response, small harmonic distortion, and great difference in function of the console. Therefore, different numbers of input channels and output marshalling consoles should be selected according to the functional requirements of the whole system.
節(jié)目源設(shè)備
Program source equipment
節(jié)目源部分包括調(diào)頻調(diào)幅廣播的接收與轉(zhuǎn)播，唱片（含CD唱片）與磁帶的重放等器材和設(shè)備。由于節(jié)目源部分輸入電平低，因此，所有器件和設(shè)備都須保證靈敏度高，信噪比大，失真度小，可靠性好。
The program source part includes the reception and retransmission of FM and am broadcasting, and the playback of records (including CD records) and magnetic tapes. Since the input level of the program source is low, all devices and equipment must ensure high sensitivity, high signal-to-noise ratio, low distortion and good reliability.
傳聲器的選用
Selection of microphone
傳聲器是擴(kuò)聲系統(tǒng)的級(jí)“入口”，自然聲源信號(hào)經(jīng)過(guò)傳聲器聲--電轉(zhuǎn)換后的輸出電壓，經(jīng)調(diào)音臺(tái)與功率放大器兩級(jí)信號(hào)處理與放大，饋給音箱系統(tǒng)，其放大倍數(shù)可達(dá)數(shù)萬(wàn)。
The microphone is the first level "entrance" of the sound reinforcement system. The output voltage of the natural sound source signal after the acoustic electrical conversion of the microphone is processed and amplified by the mixer and the power amplifier, and fed to the speaker system. The amplification factor can reach tens of thousands.
That's all about the selection of stage audio equipment. You can refer to it. For more information, please visit our website http://www.gulfbaader.com Consult!
