誤打誤撞下 新手調教十仔 phase 及 距離 分享.

papercut

我發覺前罝eg 9尺，將subwoofer set 多12尺（9+12=21尺後）再set phase,效果明顯聽到左右大細聲唔同!所以我覺得set subwoofer個距離，係因你個前置距離+多12尺去set,而唔係因subwooer實際距離去set.

     In the instance of Home Theater processors, there is an easy method. We can take advantage of the somewhat flawed concept of "speaker distance settings" to perfectly fix the sub timing issues. Simply set ALL the top speakers ( L C R Ls Rs) to 7 feet where they belong, and set the sub distance to 18-19-20 feet.Now, because all consumer equipment operates backwards (!!!) you are introducing 10 msec delay TO ALL THE TOP SPEAKERS. Now you can fine tune the phase control on the sub to add a bit more delay to perfectly match the mains and the results should be spectacular. My test CD and the two different procedures to accomplish this are all carefully explained here:

我既 set 法係 當 LCR LS RS 係 7呎. 佢叫你將 十仔 DISTANCE 較到 18-20呎.

我羅個中間數 19呎除 7呎 = 2.71倍   再乘 番你 前置同皇帝位距離.

我用呢個方法去較又真係 好左.

咁其實係咪睇前置左，右距離就夠？因為後置同前罝離皇帝位距離唔同...

    當然各聲道同一距離梗係最好啦，但大部份屋企都無可能，

所以amp入面至有distance調整呢個function.

十仔最緊要同前置in phase.

即係無論隻十仔擺幾遠都唔洗理？

    試左！我個前左9.2尺+前右9尺=18.2尺／2。攞中位數=9.1尺，再X2.71=Subwoofer set 24.6尺。
跟住播80hz聲，再較phase，坐係皇帝位聽到D頻係正你前面出，咁就攪掂la!!!!!

    補充一句，subwoofer係正前面,唔一定係set phase 0!
因為我set 左2次(叫我阿爸幫我扭phase,我坐皇帝位聽），一次由0-180,另一次由180-0去set,2次得出個結果一樣！！！都係set左去90過d,around 115

希望幫到大家

我的speaker 9', subwoofer 10.5', 用22.5 set distance, 80 set phase, set 完校果比以前好好多，thank you!
