弟日前買台marantz sr-8000(水貨),因為心裡一直毛毛的(電壓問題,peak燈,source direct),去原廠網站www.marantz.co.jp問了些問題...

1.能在110v使用嗎?
2.CD類比輸入時PEAK燈一直亮有何影響?
3.source direct時,PEAK燈為何又不亮了?
4.source direct時hdam還在工作嗎?

原廠網頁要求填入的資料因為我不懂日文亂寫一通,問題也用英文寫...兩個工作天我就收到回覆,不得不佩服日本人的敬業精神...在這邊跟許多網友學了那麼久,今天總算有所貢獻了

We have received your inquiry with many thanks.

Please be informed of our comments for your inquiry is as below;

1. Does Japanese 100V version work well at 110V?
According to our engineer, it will not be a problem if you drive SR8000 by 110V max.
However, in all of the countries, the actual voltage will not be stable, maybe +/-10%, against the rating AC voltage.
Therefore, we will not be able to guarantee the products under your circumstance.

2. The peak indicator lighting when using analog CD Input?
At the analog CD input, the Analog input signal is converted to Digital signal, then supplied to DSP board.
There is a limited input level that is fixed by Dolby standard for this circuit.
Therefore, the indicator is lit on when the level is close to this limitation.
It is only way to turn on "ATT (Attenuation)" to avoid this when you use Analog CD input.

3. The peak indicator when Source direct mode is chosen?
At Source direct mode, the signal bypass the DSP board, and it will not touch with any limitation of DSP signal level.
Thus, it is normal if there is no peak indication at this mode.

4. Bypassing HDAM circuit?
It is not possible to bypass HDAM even Source direct mode since HDAM is one of our key point to decide the sound quality.

We hope you understand our explanation, and wish you enjoy pure surround sound life with our products.
