請教 pre out 問題。。。
自己都搞到亂哂龍。。。{:6_168:}其實以下幾種接駁方法有咩分別？（定我自己搞錯？！{:6_136:} ）
1. Bdp > (hdmi) > AV amp > pre out (rca) front > 2 channel amp > front speaker
2. Bdp > 7.1 audio out (rca) front > 2 channel amp > front speaker ( 其餘 channel 全部經返 bdp >( hdmi) > AV amp )
3. Bdp > 7.1 audio out (rca) front > AV amp > front speaker ( 其餘 channel 全部經返 bdp > (hdmi) > AV amp )
4. Bdp > 7.1 audio out (rca)All channels > AV amp > All speakers
想問其實有無駁錯？會唔會有解唔到碼既問題？
其實 Bdp 既 7.1 audio out 幾時先會用到？定係多數只會用響 front speaker ? 本帖最後由 wklie 於 2017-1-4 12:04 編輯
Assuming we're talking about video only (not SACD, etc.):
I think 1 makes the most sense.
I do not recommend 2 / 3 / 4.Setup 4 may make sense only if your BDP supports a new audio format that your AV Amp does not, even then it is not likely to be better, unless your BDP has really good analog parts. 1. Bdp > (hdmi) > AV amp > pre out (rca) front > 2 channel amp > front speaker
>>>you are using the av-amp to decode, also via the av-amp to calibrate each channel but for the front, av-amp only act as preamp, the 2ch act as poweramp.
2. Bdp > 7.1 audio out (rca) front > 2 channel amp > front speaker ( 其餘 channel 全部經返 bdp >( hdmi) > AV amp )
>>>bdp to decode and av-amp can't calibrate synchronize all speakers, i don't think it will work as good as #1.
3. Bdp > 7.1 audio out (rca) front > AV amp > front speaker ( 其餘 channel 全部經返 bdp > (hdmi) > AV amp )
>>>will it work? i doubt it.how to set the av-amp to accept rca(for front) and hdmi(for the rest) at the same time.
4. Bdp > 7.1 audio out (rca)All channels > AV amp > All speakers
>>>you are using the bdp to decode, but can you calibrate each channel?
最正常做法
Blu-ray Player HDMI>>>>AV Receiver
L/R RCA >>>2 channel Amplifier RCA input
AV Receiver L/R RCA Pre-out>>>>2 channel Amplifier AV Bypass

師兄，即係二選一做？
如果 2 channel amp 有 bypass 就用 av amp pre out L/R 俾佢？

我就係有懷疑 2,3,4 會唔會 sync 唔到前置？{:6_136:}
同埋 av amp 可能做唔到 calibration ！
所以我自己都有的亂！{:6_168:} wklie 發表於 2017-1-4 11:44 static/image/common/back.gif

我都係指睇戲！（因為我唔會用 bdp 聽歌！）
即係點都係俾 av amp 解左碼先俾返 2 channel amp 出前置係最好！？ 我就咁
BDP HDMI --> AV AMP --> pre out 去Active speaker 同其他channel
BDP RCA --> 2ch --> 2ch Speaker blackcolor 發表於 2017-1-4 12:23 static/image/common/back.gif

師兄，即係二選一做？>>>>>>>兩種一齊用
睇戲時會由Blu-ray經HDMI畀digital畀AV Receiver decode同D/A處理
處理後會由AV Receiver經RCA pre-out畀2 Channel Amplifier推動喇叭
聽歌時由Blu-ray做D/A處理經RCA out畀2 Channel Amplifier推動喇叭
如果 2 channel amp 有 bypass 就用 av amp pre out L/R 俾佢？ 正確
