我睇doby公司網址，FH其實唔係atmos之一，FH只係把前置上面聲音，加大以出現的東西 ...

因為FH喺Atmos出現之前已經有，所以唔屬於Atmos入面，但我諗如果將FH喇叭線插去Atmos TF, 唔知個效果好唔好呢？

我都唔識
個人理解如下
ATMOS是多了一度從上而下的聲道

Wadee兄

上述幅圖唔係Dolby Atmos嘅官方圖片，只係Manartz 7702 Manual入面嘅圖，文字所述為

0 This unit is compatible with Audyssey DSX®, Dolby Atmos and DTS Neo:X which
offers an even wider and deeper surround sensation. (v p. 304, 305, 308)
When using Audyssey DSX®, install front wide speakers or front height speakers.
0 Use the illustration below as a guide for how high each speaker should be
installed. The height does not need to be exactly the same.

please refer to p.35, p.38 and 52about speakers placement of Dolby Atmos and DTS: Neo:X

http://us.marantz.com/us/Support/Pages/Manuals.aspx

Dolby Atmos 家庭模式最多可以安裝到34個喇叭，24 speakers on the floor and 10 speakers
producing overhead sound，而文中亦有現時巿面上的機種7.1.2作speaker placement嘅指引，
但兩者擺位係無包括Front Height 及Rear Height。

Please refer to the picture in P.9 and P.15 of Dolby Atmos for Home Theater

http://www.dolby.com/us/en/techn ... he-home-theater.pdf

Dolby Atmos 只有Top Front，Top Middle及Top Rear，無Front Height及Rear Height的。

的確太多制式令人混淆。

如果無睇錯，3030/LX88/5200都好似無左FH插位,只有FW

AAA1

See Onkyo 3030 manual
Dolby Atmos allow 3 type of speakers: a. Front height, rear height  b. Top front, top middle, top rear  c. Atmos speakers
But only 4 pairs of speaker terminals only

小弟未換機
題外話
如果買atmos amp
因家居環境唔玩atmos
咁咪冇得玩FH?

我都未換機所以唔知，唔知係咪預你玩Atmos，放棄左FH, 我都係估下

AAA1

According to Onkyo 3030, only height 1 and height 2/front wide terminal connections
So you need to give up front wide if you connect 4 speakers for Atmos
Also you need to choose the 2 pair of speakers configuration for Atmos
That means you cannot connect FH, RH, Atmos, top front, top middle and top rear at the same time and switch between them without switching the speaker terminals
Hope next generation amp can have more static speaker terminals

Another issue is Dolby suggests using top speaker with more dispersion rather than directional

但我個日問過onkyo
佢答我可以用FH玩
唔知佢意思係咪指效果都唔錯
要再努力研究

我只係指標準嘅擺法，overhead speaker係放喺ceiling唔係前牆嘅高位，當然因家居環境不容許下嘅妥協擺法用front height 當front top係都可以,就好似將surround 同surround back一字排開放後牆一樣。
