TA7796P组成的均衡器前几期的我们完成了2×35W带音调控制的卡拉OK组合机的制作。为了对高低音信号进行更细致的修饰处理,使音色更完美动听,本期将在以上制作的基础上,加上五段均衡电路,使设备的档次在原基础上又上一个台阶。多频段图示均衡器也称图形均衡器,这种音调调节电路是将音频的全频信号(20Hz～20kHz)或其主要部分,分成多个频段,分别进行提升和衰减,以便根据需要对频率特性进行细致的调整。这除了可以改善音质、音色以外,还可以提高信号传输质量,如通过调整降低磁带放音的本底噪声,消除卡拉OK演唱时
Equalizer TA7796P composed of the previous period we completed the 2 × 35W with karaoke OK tone control machine production. In order to bass and bass signals for more detailed modification process to make the sound more perfect, this issue will be based on the above production, coupled with five stages of equalization circuit, so that the grade of equipment in the original foundation to a higher level. Multi-band graphic equalizer also known as graphic equalizer, this pitch adjustment circuit is the audio frequency signal (20Hz ~ 20kHz) or its main part, divided into multiple bands, respectively, to enhance and attenuation, in order to be on the need for frequency Features detailed adjustments. In addition to improving the sound quality and sound quality, it also improves signal transmission quality, such as reducing the noise floor of tape playback and eliminating karaoke performance
