Line out一定要接耳擴,直接聽聲音一定不好,功率不夠,只是聲音大聲罷了。
是我的耳擴和耳機等級不夠嗎?
借個測試圖讓您參考

上面也有很多連結,
裡頭討論都直接講明了,
當然您聽得高興就好
......恕刪
恩......雖然我沒有X5,不知道他是否的有這個問題,不過那個圖表好像有點問題......
32歐姆的阻抗對lineout來說太低了,他無法提供大量的電流做為低頻的長時間輸出(半週期長)是很正常的。
且原po也寫道:
Zephyron 寫:Its true that lower impedance will cause a rolloff on the X5's lineout, and high impedance solves the problem, but folks tend to use them with earphones or headphones in portable situations that in general, have a not so high impedance (e.g IEMs, the highest of which is the Shure e5c so far, with 110 Ohms). Even through the line in of an amp (maybe say a 92 Ohm impedance adapter mini-to-mini cable), the bass rolloff is audible.
The X5's lineout is flawed anyway, so its best to just use the headphone out to do the amping.
How much load does one need when one's on the go anyway?
建議樓主還是自己測試一下會比較好。
另外,我是新手,剛到貴寶地請大家多多指教,如果有錯也請多包含。
