想不到第一篇不是心得文,而是奇怪的問題文…
如題,小弟原本服役系統是:2gougo2cmdardas rca轉xlr轉接頭si a14m
因為長年沒使用過平衡,之前在某臉書社團看到無源前級團購就跟了。
(無緣前級是ppa 02b,design by mr k)
原本接上去聲音是都沒啥問題,今天在試音量的時候發現幾個bug。
喇叭原廠建議我用無衰減,但是目前怎麼調都怪怪的,所以現在固定在1/3( -14db的地
方),然後因為好奇我看了一下說明書…才發現前級原廠說明是同時使用rca跟xlr最小輸
入阻抗要20kΩ…可是a14m最小阻抗是10kΩ…這樣是不能使用的意思嗎?
可是hugo2輸出印象只有0.025Ω,實在很難想象經過變壓放大就會到20kΩ,想請問有沒有用
過類似裝備的版友,目前聽起來是沒啥問題,另外想請益因為hugo2純dac模式好像只是音量直接調到紫色,是不是
降低hugo2的音量然後喇叭調整成無衰減比較好,音量用前級調整這樣,以上問題,先感
謝各位版友。
