同一对音箱,有朋友试过分别接两种不同阻抗输出,对比过声音的不同吗?
请朋友们说说体会,谢谢,

胆机输出变压器的4欧和8欧输出是用来与相应阻抗的音箱搭配,以至达到最佳声音效果的。

试过都是对应较好听

谢谢各位朋友,4欧与8欧两种输出,如果与音箱的阻抗不配,也不会造成伤害吧

Short answer: Must try both 8ohms and 4ohms taps, hear which one you like.

Long answer:
Output transformer is used to match tube with speaker impedance.   Connect to the right tap can yield minimum distortion and maximum power transfer from tube to spk.

However, spk impedance is not constant across the whole frequency spectrum; a nominal 8ohms speaker may have impedance range from 4 to 10ohms.   A nominal 6ohms spk may have impedance range from 2 to 8ohms and so on.  So you never know which tap give min distortion and max power until you really hear the result, or use equipment to measure the actual output.

功放4欧的输出要比8欧的输出可匹配的音箱品种相对要多
