我是剑桥740A功放带前级输出可和一台后级组成双功放 请教怎样选择这台后级

jp

最好同系列的后级，如果找不到，选MYRYAD Z160也是很好的，不过Z160最近又卖完了，据说会有最新的Z162到货，功率仍为50W/声道。

WW0994

MYRYAD Z160每声道50W(8欧) 而我的剑桥740A每声道100W(8欧)这样搭配是否能平衡 据说需要输出阻抗的施配 这是啥意思?请专家讲的详细点好吗?多谢

就是合并机的输出阻抗要和后级的输入阻抗相匹配、同时增益也要匹配，一般来说，合并机的输出阻抗要远小于后级的输入阻抗为佳。所以，最好选回同系列的产品。

怎样才知道合并机的输出阻抗是多少

要看说明书上有没有标注。

说明书全是英文的没法看懂 真心求您给看看这方面的资料给个最理想的搭配方案来推好我即将入手的AE309

你看OUTPUT IMPENDENCE这项是多少？如果没标，就没办法了。
