音壓計使用

btmagic

yes, the master volume should be keep at a reference level for the tone.

幫師兄補充少少, onkyo入門機既master vol. 同pink noise都有關係, 我要開到部機既master vol. 60度先至會接近75db

你指用pink noise時轉動master volume都有影響？

btmagic

唔好意思！問多個問題，我5隻喇叭都順利調至75db，
但隻subwoofer調到盡都係得71db左右，因subwoofer係有源，
原本subwoofer 既VOL 大約11點鐘，係咪要將VOL調大D至1點至3點鐘等？
直至到達81db先個得？！
謝謝！

我本身無音壓計，一直只係用隨機送既mic靠機內的auto setup 校正(好似叫Audyssey 2EQ)，小弟用既係onlyo607，咁唔知同用音壓計校有無分別呢？

多謝各位Ching分享...

我上星期試過做完auto setup再用音壓計測試，基本上都準，有兩隻speaker差2db，subwoofer就只去到69db。我估因為auto setup的結果係會將front同center都set做full range，所以subwoofer單獨的output係細咗。

    To AVmilk Ching about balancing speaker level:

I am a Yamaha Z7 user but encounter problems balancing my speakers' level.  If I turn my master vol to 0db and then adjust each channells output, some channels (front) and subwoofer are outputing so high a test tone level that even if I give the channel a -10db adjustment ,   the SPL reading is always > 75 db.  Maybe there is somehting I don't understand well.  

What if I just leave my master vol to level lower than 0 db e.g -10 db to start off with and make sure each channel ultimately is 75 db.  Is this method ok?
Hope you understand my question and pls kindly advise
