音响设备对各种器材的功能和使用都十分的了解，具备的理论知识、精 确地听音能力、极强的调试水平、强调故障诊断与排除能力。一个设计合理的音响系统，不应只关注电声系统的设计与调试，而应该考虑到实际的声音传播环境，并在其中进行精 确的现场调音，因此说难点在于进行系统的设计和调试。
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.
音响系统的追求目标是得到理想的听音效果，如在家中可欣赏到影剧院的音响效果。但家庭又不同于影剧院，因此对欣赏不同性质的音响，要求的声学效果也不一样，对流行音乐、古典音乐、轻音乐等要求能正确还原各种乐器，对欣赏影片，要求有音效的现场感、包围感等。
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响领域里面听到过，对此还很陌生。这要从音箱的分类来谈起，音箱按照用途一般可分为主放音音箱、监听音箱和返听音箱几种。主放音音箱一般用作音响系统的主力音箱，承担主要放音任务;返听音箱又称舞台监听音箱，一般用在舞台或歌舞厅供演员或乐队成员监听自己演唱或演奏声音。而监听音箱呢，是用于听音室、录音室等制作音频节目时的监听使用。它具有失真小、频响宽而平直、声音结像好、对信号很少修饰等特性，因此能真实地重现声音的原来面貌。
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.
说到这里，我们需要额外解释一下音染这个词。音染是将声音本质、原声受到了额外的干扰，出现了多余的声音，或者改变了声音的原貌。监听音箱的本质就是尽量杜绝音箱对声音造成的音染
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
