频率均衡器在音响设备中能修饰音色音质、改善器材性能、渲染音响效果,受到音响爱好者的普遍欢迎。现在较流行的频率均衡器有图示式、参量式等,这些电路都能有效地改变声音频谱中高、中、低音的成分,从而满足不同层次的音乐爱好者在不同的听音环境中对不同节目的欣赏要求。但这些频率均衡器都有一些共同的弱点,如线路比较复杂,需要使用较多的集成电路和阻容元件,且容易引进噪声,再如在实际使用时调节较为麻烦,众多的电位器使初用者手足无措,特别是当一些“外行人”调节不当时,放音效果适得其反。为了克服这些不足之处,国外的有关研究机构采集了大量的数据(包括不同的听音环境、不同的节目声源、不同的音响器材、不同的音乐类型、不同的欣赏要求……),并用计算机来作模拟处理,结果
Frequency equalizer in the audio equipment can modify the timbre sound quality, improve equipment performance, rendering sound effects, audio enthusiasts generally welcomed. Now more popular frequency equalizer graphical, parametric, etc., these circuits can effectively change the sound spectrum of high, medium and low bass components to meet different levels of music lovers in different listening environments for different Appreciation program requirements. However, these frequency equalizers all have some common weaknesses. For example, the circuit is relatively complicated, more integrated circuits and RC components are required, and noise is easily introduced. In addition, the adjustment is troublesome in actual use. A large number of potentiometers make early Users are overwhelmed, especially when some “layman” is not properly adjusted, the playback effect is counterproductive. In order to overcome these shortcomings, relevant research institutes abroad collected a large amount of data (including different listening environments, different program sources, different audio equipment, different types of music, different appreciation requirements ...) Computer for simulation, the result
