Professional audio equipment has a good understanding of the functions and use of various equipment, has professional theoretical knowledge, accurate listening ability, strong debugging level, and emphasizes the ability of fault diagnosis and troubleshooting. A professional sound system with reasonable design should not only focus on the design and commissioning of electroacoustic system, but should consider the actual sound transmission environment and carry out accurate on-site tuning. Therefore, the difficulty lies in the design and commissioning of the system.

音響系統(tǒng)的追求目標(biāo)是得到理想的聽音效果，如在家中可欣賞到影劇院的音響效果。但家庭又不同于影劇院，因此對欣賞不同性質(zhì)的音響，要求的聲學(xué)效果也不一樣，對流行音樂、古典音樂、輕音樂等要求能正確還原各種樂器，對欣賞影片，要求有音效的現(xiàn)場感、包圍感等。

The goal of sound system is to get ideal listening effect, such as enjoying the sound effect of cinema at home. However, families are different from cinemas. Therefore, they require different acoustic effects for appreciating different types of sound. They require correct restoration of various musical instruments for pop music, classical music and light music. For appreciating films, they require a sense of scene and encirclement of sound effects.

可能很多人都是在音響領(lǐng)域里面聽到過，對此還很陌生。這要從音箱的分類來談起，音箱按照用途一般可分為主放音音箱、監(jiān)聽音箱和返聽音箱幾種。主放音音箱一般用作音響系統(tǒng)的主力音箱，承擔(dān)主要放音任務(wù);返聽音箱又稱舞臺監(jiān)聽音箱，一般用在舞臺或歌舞廳供演員或樂隊(duì)成員監(jiān)聽自己演唱或演奏聲音。而監(jiān)聽音箱呢，是用于聽音室、錄音室等制作音頻節(jié)目時的監(jiān)聽使用。它具有失真小、頻響寬而平直、聲音結(jié)像好、對信號很少修飾等特性，因此能真實(shí)地重現(xiàn)聲音的原來面貌。

Many people may have heard it in the field of professional audio, which is still very strange. This should start with the classification of speakers. Speakers can be generally divided into main playback speakers, monitoring speakers and back listening speakers according to their purposes. The main playback speaker is generally used as the main speaker of the sound system to undertake the main playback task; Return listening speakers, also known as stage monitoring speakers, are generally used on the stage or in song and dance halls for actors or band members to monitor their singing or performance. The monitoring speaker is used to monitor audio programs in listening rooms and recording studios. It has the characteristics of small distortion, wide and straight frequency response, good sound image and little modification of signal, so it can truly reproduce the original appearance of sound.

說到這里，我們需要額外解釋一下音染這個詞。音染是將聲音本質(zhì)、原聲受到了額外的干擾，出現(xiàn)了多余的聲音，或者改變了聲音的原貌。監(jiān)聽音箱的本質(zhì)就是盡量杜絕音箱對聲音造成的音染

At this point, we need to explain the word Yinran. Sound dyeing is that the essence of sound and the original sound are subject to additional interference, resulting in redundant sound, or changing the original appearance of sound. The essence of monitoring speakers is to try to eliminate the sound pollution caused by speakers
