| [#163] 唱片最後嗰首超衰聲點搞? 現在巧多新制作懷舊唱片， A / B内圈盡頭足夠可以貫錄多兩首歌曲， 但！支唱針以經進入完成。 當然A / B兩面的歌曲容量，係會減小一至兩首歌曲， 以前80s'的唱片二面係十幾首歌曲，密麻麻， 新制的LP 係小咗3-4隻歌，內圈就濶咗。 最後修改時間: 2022-03-30 01:38:59 |

| [#161] 唱片最後嗰首超衰聲點搞? 近十年巧多新制作唱片LP黑膠碟生產功敍以經冇行内圈， 由以往A / B 各7-8首歌曲， 減至5,6,7首歌曲，内圈係濶咗小小， 禾買巧多新LP , 留意到新舊唱片巧大分別。 |

| [#158] 唱片最後嗰首超衰聲點搞? 見猛波兄 post 左張 SAEC WE-308SX 既 ad 出黎，見到個定價，當堂嚇左一跳。 不過小弟而家就用緊 SAEC WE-407/GT 。同廠但不同型號。 |

| [#156] 唱片最後嗰首超衰聲點搞? Yes, this is the one I've been using for years. Cost me only $30 hehe. A very sweet girl's voice will guide you thru the process on track 2 The vertical and horizontal resonance tests are also very useful. More sensitive than the HFN&R disc IMHO.  |

| [#155] 唱片最後嗰首超衰聲點搞? May I ask which Ortofon direct cut test record are you using (0001 ? 0002 ?) and which track to check azimuth please ? The below picture is 0001, is it that one ? Thank you sir ! :format(jpeg):mode_rgb()/discogs-images/R-4314437-1388508002-9914.jpeg.jpg) |

| [#154] 唱片最後嗰首超衰聲點搞? More In the real world, there is always some crosstalk but minimizing it maximizes channel separation and maximizing channel separation maximizes soundstage width and soundstage symmetry. So we want the stylus to sit perfectly centered in the groove. Were the stylus perfectly aligned with the cantilever, cantilever perpendicularity to the record surface would guaranty minimum crosstalk and correct setting of azimuth. But as we described in our discussion of SRA, styli are rarely set correctly in the cantilever in terms of SRA and that's also true with azimuth. Usually the stylus is canted slightly to one side or the other, thus, cantilever perpendicularity to the record surface is no guaranty of correct azimuth setting. Also, what are the odds that the coil assembly will be perfectly aligned and symmetrically placed between the 45/45 angle of the record grooves? Not great. And for cartridges where the motor is a complete assembly that's affixed within a separate body, what are the odds of that being symmetrical? Not great! And that's why it is virtually impossible to correctly set azimuth by eye or with a mirror or with a balancing beam. So how do you do it correctly? Electrically. Now that does not mean putting the channels out of phase with each other, summing to mono and adjusting azimuth until the signal "nulls" out a is suggested on some test records. That does not adjust azimuth! That simply balanced the outputs of the channels. It does not guaranty that you've minimized crosstalk and maximized separation, which is what you're really trying to do. |

| [#153] 唱片最後嗰首超衰聲點搞? 睇吓Stereophile個Michael Fremer點講 http://www.analogplanet.com/content/crazy-little-thing-called-azimuth-part-2 睇清楚啲佢都話係靠compare crosstalk唔係用左右電平來set azimuth的 其實最快靚正平都係我用開隻Ortofon direct cut test record，尤其係set 啲單點臂幾分鐘搞惦唔洗搞到身水身汗 |

| [#152] 唱片最後嗰首超衰聲點搞? FOZGOMETER AZIMUTH RANGE METER 要$2xxx，平貴見人見自，不過我一直都有推薦比朋友同借比人試，外國的 權威評論亦極高。 當調整Azimuth時，可能只調節+-1度，讀數已有改變，所以使用時要求是耐性。 http://www.musicdirect.com/p-1278-fosgate-fozgometer-azimuth-range-meter.aspx 最後修改時間: 2015-01-24 12:32:58 |

| [#150] 唱片最後嗰首超衰聲點搞? 孟波兄，如果純粹用左右電平是否平衡作調校，真的不可作準，我在最靚情況下，量度出左右差距 140mV 可能是碟問題，可能是放大器問題，可能。。。太多可能，最重要耳仔收貨就得 :P 不過要常量度做先有個參考點及日後自己參考用  最後修改時間: 2015-01-24 11:10:18 |

| [#149] 唱片最後嗰首超衰聲點搞? 當你調正好Azimuth之後，個唱頭可能歪埋一邊，我的調較是看錶上讀數作準，否則一係唔好用。 最後修改時間: 2015-01-24 11:06:48 |

| [#146] 唱片最後嗰首超衰聲點搞? 如果純粹用左右電平是否平衡作調校，但大部分有獨立出世紙的高級唱頭，看到左右的輸出也不是完全相同的，或者線圈架和針尖角度製造時有偏差，應以何者作準？ |

| [#145] 唱片最後嗰首超衰聲點搞? 好多時玩黑膠，在調較上都忽略了Azimuth，大部分人只會用肉眼去睇。其實就算有儀器去量度，在調整上亦要花上不少功夫及時間才能調到達至右左平衡，當你真調正好Azimuth之後，會發覺聲音的空間感更立體及提升，這亦是玩黑膠其中之樂趣。 最後修改時間: 2015-01-24 10:41:15 |
