| [#31] 好多cd 都是反相錄音, 聽返正相好多功夫, 有簡單解決 ? Can I clarify if we are talking about out-of-phase or inverted phase..? patrickwong c-hing, thank you for your help..!! but my company block youtube so I will try at home tonight.. thanks again.. ^^ |

| [#33] 好多cd 都是反相錄音, 聽返正相好多功夫, 有簡單解決 ? patrickwong c-hing, yes, it always confusing.... I suppose many c-hings here are talking about invert phase... Let me clarify my position sin.... out-of-phase: If any one CANNOT hear the difference please cut your head.... inverted phase: If any one can hear the difference, I cut my head for you to seat.... XD |

| [#34] 好多cd 都是反相錄音, 聽返正相好多功夫, 有簡單解決 ? For a good hifi system, NOT EXPENSIVE SYSTEM, everyone should hear the difference between 0 phase and 180 phase!! _____________________________________________ hiphopzz c-hing That's the point. Yes, NOT out-of-phase, inverted phase (0 degree to 180 degree). If you are familiar with classical music, your system is well presenting the recording, you can hear this. Even though a non-audiophile guy (my wife) can hear the different. When the phase is correct, first you hear more airy from wood winds, you hear more details from violins, the position of all musical instruments can be clearly identify its position in the orchestra. Many many to prove but my poor English can describe this. So that that I don't know how to type Chinese using PC. |

Sometimes audiophiles get confused. Which is which? Absolute polarity means that a leading edge is heard as a positive pressure wave or compression (higher density), not a negative wave or rarefaction (lower density or decompression). ......" |

| [#39] 好多cd 都是反相錄音, 聽返正相好多功夫, 有簡單解決 ? hiphopzz hing, "inverted phase: If any one can hear the difference, I cut my head for you to seat.." Every time when I press the "Phase" button of my DAC, I can hear the difference. With absolute polarity of the CD, the bass will be more solid, the voice will be more sweet and the treble will be more clear. But you can keep your head for your own use - just joking :=) Happing listening  |

Pls tell me theory behind for inverted phase... Thousand of thanks.. ^^ ...................................................................................................... digitalstereo c-hing, If you are sure there is difference, I really hope we can arrange blind test.. Honestly, I really appreciate if you can help.. Thousand of thanks.. again.. ^^ |

| [#44] 好多cd 都是反相錄音, 聽返正相好多功夫, 有簡單解決 ? digitalstereo c-hing, Thank you very much for your sharing. I read it and briefly conclude 2 points from it. Design of speaker and inserting a unity gain phase inverter The first point may be relevant since different phase of driver. Reversing phase may give more coherent phase. But the second point,I think, is quite unrelevant... Any c-hing can share idea..? ^^ |

It can only tell whether the 'physical connection' of the speakers is correct (check the correct polarity of the speakers). There are many simple ways to check the polarity of speakers (or the systems). No need to buy this expensive device for such simple task. 最後修改時間: 2009-11-12 17:21:39 |

| [#46] 好多cd 都是反相錄音, 聽返正相好多功夫, 有簡單解決 ? hiphopzz hing, yes, I am talking about "inverted phase". I just recall when I did experiment in the U on feedback/control systems, plotting input/output graphs on the motions/signals, comparing the distortion and phase shift of the input/output. People are concerned on the inverted phase because the speaker suppose will push out the cone will become suck in. People claim that they can hear the difference and the sound will be better if the polarity is correct. However, sound is reproduced by a series of vibrations , i.e. in and out motions of the speaker cone. What effect will be on the sound produced with inverted phase? I don't know and have not auditioned it before. If some C-hing has experience on this, please share. What I can imagine (from an input of a simple sine wave and cause the speaker cone to move) is just a time shift of the motion. It is still a sine wave. To my limited knowledge on electronics, different frequency will have different phase shift in the same circuit. So, does it really have effect with just making a 180 deg phase change ? It may also inverted some frequency incorrectly? |

| [#48] 好多cd 都是反相錄音, 聽返正相好多功夫, 有簡單解決 ? 係唔係反相錄音. 一般聆聽都冇問題. 如果冇資料話比你知隻碟既錄音係反相錄音定係正相錄音. 你聽唔聽得出隻碟係乜相錄音. 其實果d 音響器材有指示輸入輸出既相位, 作用係比d 錄音工程師連接器材及混音錄音時張d 相位搞清楚才開工. 確保錄音/混音出來相位正確. |
