上禮拜從朋友手上接手sta-9 接前級dac使用
第一天短時間用沒事
第二天放假長時間用 大概8個小時左右的時候
發現sta9裡發出明顯的恩恩恩恩恩恩聲
(音樂還是能正常聽)
https://youtube.com/shorts/J8oQFcuFk_4?feature=share
嚇到先關機 再開機還是一樣有聲音
後來關機個3~5分鐘再開就沒聲音了
然後我把線材拔掉 只剩電源線
機器打開去睡覺想說做個測試
大概5個小時後又出現恩聲
怕繼續使用會故障就送去內湖給進音彷檢測
說明長時間使用下有異音
但維修師傅檢測兩三天 說他上班開到下班
機器也在高負載情況下 都沒聽到機器有異音
上面影片有給師傅看過
他說他覺得是變壓器的聲音
還說有聲音是正常的
我就說可是異音聲音很明顯欸
但他那邊檢查不出問題
我就請他先寄回來我在使用看看
(師傅說明天寄)
想請教各位大大影片中的聲音是正常的嗎?
朋友用的時候沒遇到問題
有懷疑是我家裡電壓問題
但我其它設備都沒問題
量電壓也都是110v左右
還是我乾脆直接請師傅換個變壓器?
