我因此查了一下原廠說明書,發現似乎有印證我的主觀感受。 Harman Volume: This button cycles the Harman Volume function between high, low and off. Harman volume is an advanced digital signal processing technology to control playback volume. It evens out the volume level on everything you watch, improving your listening experience. Once you choose the volume level, Harman Volume does the rest. It helps you avoid volume increase from commercials, volume differences when you change channels or switch sources. It helps you listen to the perfect sound of the dialogs.
