macmini ching,

hv u try 2 channel music with Z7 ?

macmini

No, I haven't try. But I don't use AV Amp for both music and AV. No good result at all, even you pay HK$4xxxx or above in AV Amp.

昨晚又再set過套機，本來想測6個位，但太夜唔想disturb 鄰居，所以只做左三個位

First of all, my speakers are as the following:
Front: Klipsch RF52
Centre: RC52
Surround: RS42
Surround back: RS10
Prescence: Whafedale 10.4 surround
Subwoofer: SVS PC-12NSD

首先用auto setup run一次，大約20分鐘，再用SPL測下每個channel既音壓，adjust下距離，就到戲肉。  搵隻熟悉既BD，聽下聲，我自己會用concert 同 movie 呢類碟黎試。  我的聆聽空間約200sq ft.

之前睇過百事佬同其他ching既教學，因為不同牌子speaker同room size，所以因應來調節。

每先選擇manual curve，再行PEQ

1) Front L & R: 1khz + gain by 2db， 同16khz再推gain到5.5db
2) Centre，大致如上，得 1khz 會加3db, 16khz唔變
3) Prescence L & R: 62.5hz加大2db，1khz加2db，16khz加2.5db
4) Surround L & R: 62.5hz加2.5db, 157.5hz 減1.5db, 1khz + 1db， 16khz +2db
5) Subwoofer: 62.5 & 157.5 Hz 各加2db

Speaker configuration:
Front: small 80
Ctr: small 90
Surround: 100
Surround Back: 110
Subwoofer: Base - front+swf

之前覺得空間感太大，少又一份真實感，所以改改佢：
Liveness: -1db 變成 0.9
DSP: - 1db 變成 0.9
Room size: -2db  變成 0.8
所有delay值不變

after adjustments, 發現所以channel既聲音溶合相對之前自然，speaker再隱形，特別中置既聲音多一份鬆容。  Overall，detail多左，聽到再多弱音和殘響，多較似我o係 showroom試既感覺 (test with 南京，南京 MKV 版本)。  以前覺得十仔d量太多，就算speaker level 減 3db，d聲都係混濁，調教EQ有好太改善。

因為要一個完全安靜既環境，所以由1點玩到5點半先收工，而家好
