KTV济南音响设备配置要把握的功放、音响、话筒这三个要素，前面也都提到，无论配置形式上如何变化，也都在范围之内。

The three elements of the KTV Ji'nan audio equipment, audio power amplifier, the microphone, the front also mentioned the configuration, regardless of how the form change, are also included in the scope of.

济南音响功放的选择。KTV功放分为合并式KTV功放以及前后级分开的组合，按照话筒效果类型分为传统ECHO和DSP。其实传统的ECHO也是早期的DSP处理器，限于当时的技术需求及成本控制，性能不高，应用范围受到较大局限。早期设计的合并式KTV功放功率一般都比较小，配套的音响都是灵敏度较高的小功率音响，最容易出现的问题是回授啸叫(飞唛)，原因是大音量工作时功率储备不足，造成严重信号失真，再加上高灵敏度的音响失真回馈，失真被循环放大，导致回授啸叫(飞唛)。原则上，回授啸叫(飞唛)的主要诱因是失真，减少失真就可以减少回授啸叫(飞唛)的几率，但不能说绝对不会回授啸叫(飞唛)，只能说在可用增益范围内，当增益足够大的时候也会导致回授啸叫(飞唛)。也就是说，KTV的KTV功放要尽量选择大功率的。但是，功放的功率越大，音色感觉越硬，通过实际经验每通道8Ω300W以内的都可以选择。

Ji'nan selection of audio power amplifier. KTV power amplifier is divided into combination of split and merge KTV power amplifier and level, in accordance with the microphone type is divided into traditional ECHO and DSP. In fact, the traditional ECHO is early DSP processor, limited to the technical requirements and cost control at the time, not high performance, application scope is limited. Early in the design of combined type KTV power amplifier are generally small, supporting sound are low power audio high sensitivity, the most prone to the problem of feedback Xiao Jiao (Fei Ma), reason is the lack of power reserve volume work, causing serious signal distortion, coupled with the high sensitivity of the acoustic feedback distortion, distortion is cycle of amplification, resulting in feedback (Fei Ma Xiao Jiao). In principle, the feedback Xiao Jiao (flying mark) of the main causes of distortion, distortion reduction can reduce the feedback Xiao Jiao (flying mark) probability, but can not say absolutely not feedback Xiao Jiao (Fei Ma), can only say that in the available range of gain, when the gain is large enough can also lead to feedback howling (Fei Ma). That is to say, the KTV KTV should try to choose high power amplifier. However, the greater power amplifier, tone feel hard, through actual experience within each channel 8 300W can be chosen.

选择功放与济南音响 http://www.jnzqyx.com/ 的搭配非常重要，音响的阻抗、灵敏度和功率都会影响到功放的选择，一般原则是灵敏度高的音响功率相应配小一点，功放功率2倍于音响功率即可，灵敏度低的济南音响功率相应配大一点，功放功率2.5～3倍于音响功率即可，这样配置相对比较稳定。功放的音色最难鉴定，不是文字能够表达的，这也是最难的部分，也是让众多厂商能够生存的道理，音响世界很难有绝对王者，全在于个人的理解和选择。小于18平米的房间基本上一台设计优良的传统ECHO效果KTV功放足以胜任。但是，出于经营管理需求，当你把音响效果看成一项产品来对待，传统ECHO会造成音响效果的不确定性，每个客人的效果调试要求可能让管理者永远无法把效果确定在统一的位置上，也会让DJ疲于奔命。使用带有DSP处理器功放的第二个理由是，传统的ECHO效果处理芯片频响范围窄(小于8KHz)，采样频率低，在要求大功率输出的环境下就显得混浊无力，不能打远，穿透力不够。

Selection and collocation of power amplifier and the Ji'nan sound is very important, acoustic impedance, sensitivity and power will affect the power of choice, the general rule is that the corresponding sound power with a high sensitivity, power amplifier 2 times in the sound power, sound power sensitivity of Ji'nan low rate corresponding with a power amplifier, 2.5 - 3 times the sound power can be, this configuration is relatively stable. The most difficult to identify the sound power amplifier, not words to express, this is the most difficult part, but also for many companies to survive, the world of sound is difficult to have an absolute king, is full of personal understanding and choice. Less than 18 square meters room basically a good design of the traditional ECHO KTV power amplifier capable. However, for business management needs, when you put the sound effects as a product to treat, the traditional ECHO will cause the sound effect of uncertainty, debug each guest effect may allow managers to determine the effect of never in a unified position, also can let DJ exhausted. The use of DSP processor with PA second, traditional ECHO processing chip frequency range (less than 8KHz), low sampling frequency, at the request of high power output environment becomes turbid weakness, not far, lack of penetration.
