驾势双声道后级 CA-2300
 
 
 
 
 
CA-2300两声道后级,拥有每声道300瓦输出
驾势双声道后级 CA-2300


  新Delta系列后级有许多特点,首先是新的微型驱动级电路,原厂说这个新的电路几乎没有噪讯和失真的问题,提供最精确的讯号控制,同时,整个放大的过程是在一块新的6层电路板上进行,大幅缩短了讯号路径。还有新的电源设计,待机状态时仅消耗0.5瓦。

  而最重要的特色应该是Classe的ICTunnel(icy tunnel)技术,这是一套主动式冷却系统,或者是把它看作是一套恒温控制系统,会比较容易理解一些,ICTunnel会帮助扩大机快速达到理想工作温度,并利用感应器和微处理器将温度保持在理想状态,Delta不论扩大机在多严苛的条件下工作。
