发帖数: 351 | 1 刚买了Sonus Faber (second hand). When I listen to some CDs(正版), 高音喇叭近听有咝咝噪音, 特别是当CD中只有中低音. When DVD is turned off, but receiver is on, there is no 咝咝 at all.
When I use TV, especially listen to talk show, there is no 咝咝噪音 at all.
Please help me where is the problem?
My setup:
------------
DVD player: Panasonic DVD-RV65 (old, but it has 24bits), connected to
Receiver using digital optical.
Receiver: Denon AVR3805
The speaker line is cheap.
How to solve it? Did I buy a bad speaker or receiver? Is it because that the
voltage power is not enough for receiver ? Or is it because of the cheap-
made speaker line?
BTW, It is so beautiful to play Mutter's violin, there is no 咝咝噪音, and
it is so sweet and pure. 我得特别表扬一下SONUS FABER，弦乐太美了。
Thanks a lot | A***o

quote: 如果在正常工作状态下产生的，主要集中在中高频上，说明功放的某些元器件
随着时间的推迟，出现不稳定的状态，产生的热噪声！
其实这也不难解决，只要将功放外壳接地，就可杜绝此噪声的干扰，还你宁静。。。。
。。试试看！！！
另外， 晚上回家再试一下单独给功放接电. 我现在电视，电脑，功放，DVD，游戏机都
接在一个有backup能力的接线板上（一根线）。 不知道是不是电压不足。
因为有时WII游戏机开不了机，换个单独的插线，游戏机能工作。可能接线板不好，
black friday's garbage.
any other thoughts? You advices are appreciated. | f*******e

Between the songs, there is no 咝咝噪音 at all. I think that we can exclude
the speakers.
Perhaps DVD player or receiver? | i*d

噪音时有时无，而且那receiver设计就电源地悬空。

发帖数: 82 | 10 还是觉得应该换个地方试试这张碟。不能过分信赖CD。
很多年以前买过一盘卡带。听到中间总发现有个地方出现极短暂的停顿。拿到音像店去
换，工作人员也听出来了，但直接看电平输出，又没发现问题。换了一盘也一样。大家
猜测是母带就有问题。
