ABB CI854AK01 模块

单增益前级的目的在于:将前级想象成一个缓冲器(Buffer)，在英文意义里，Buffer具有隔离、缓冲的作用，亦即不改变讯源器材的信号强度，但以高输入阻抗接收，以低阻抗输出的观念将讯号送出，因此单增益前级便具有阻抗转换的功能。市面上的单增益前级并不多，较主要原因在于增益往往不足，音量开至较大依旧意犹未尽，国产厂商交直流工作室推出的Encore前级，正是单增益前级的具体代表。这部前级使用孪生场效应晶体管做输入，以ZTX双极性晶体管做输出，具有高输入阻抗、低输出阻抗的特性，由于零件较少，因此S/N比奇高，将音量开至较大，耳朵贴近高音单体听不到任何嘶声，音色通透无染，细节呈现自然，是一部价格较其便宜音质较其优异的单增益前级。GENERAL ELECTRIC TED134YT100
