在寫信問過原廠後得到下列的反饋(GOOGLE翻譯) T8 uses a pure analog design architecture, but analog potentiometers and circuit construction cannot completely eliminate the phenomenon of left and right crosstalk, and a slight weak signal is a normal phenomenon.Thanks for your kind understanding. T8採用純類比設計架構,但類比電位器與電路構造並不能完全消除左右串擾現象,訊號稍弱屬於正常現象,感謝您的理解。
