一般商品音响器材,由于厂家在设计、用料时考虑成本和性能价格比,不可能全部使用高级音响专用零件,因而音质未达完美程度。因此,广大音响发烧友自己动手,更换对音色有较大影响的元件,改革有关电路,使音响器材改进升级,称之为“摩机”。下面是笔者对“达声DS—2O00N型”组合音响的摩机实践和体会。一、对扬声器系统的改进在整个音响设备中,一般均由声源、前置放大和控制设备、主放大器、扬声器系统四大部分组成。由于技术发展程度不同,各部分对音质的影响也有差异。其中放大电路多年来由于器件多次更新换代,各类型放大器层出不穷,发展比较快,比较成熟,与扬声器和声源相比,各项指标均做得较高。而扬声器系统发展较缓
General merchandise audio equipment, due to manufacturers in the design, materials, cost and cost performance considerations, can not all use advanced audio special parts, so the sound quality has not reached the perfect level. Therefore, the majority of audio enthusiasts do it yourself, the replacement of the tone has a greater impact on the components, the reform of the circuit, audio equipment to improve the upgrade, known as the “motorcycle.” The following is the author of “Dasheng DS-2O00N-type” combination of audio machine practice and experience. First, the improvement of the speaker system In the entire audio equipment, generally by the sound source, preamplifier and control equipment, the main amplifier, speaker system consists of four parts. Due to different degrees of technological development, the impact of various parts of the sound quality is also different. Amplifier circuit which over the years due to multiple device replacement, various types of amplifiers after another, the development of faster, more mature, compared with the speaker and sound source, the indicators are done higher. The speaker system developed more slowly
