Hi Anton, when I use high pitch test my circuit IC Pad, I have to put it close to my ear to hear the sound. My impression is that I should hear it like one foot away. Does it mean that either my cable or IC Pad is not functioning correctly?
嗨，安東，當我使用高音測試我的電路 IC Pad 時，我必須將它靠近我的耳朵才能聽到聲音。我的印像是我應該在一英尺之外聽到它。這是否意味著我的電纜或 IC Pad 無法正常工作？
