日前購入了Yamaha RX-V685
原因是因為他有兩個HDMI out
一個HDMI out是去電視, 另一個我原本打算夜深人靜的時候, 接到我的Sony 無線耳機看片(本身是可解碼DTS/AC3等等的訊號)
當我用電視撥放Netflix 帶有AC3 的影片時
電視 HDMI ARC 將聲音送到擴大機 HDMI Out 1 (帶ARC)時, 擴大機可以順利收到AC3 的信號並且由自身喇叭撥放
但, 當我利用HDMI out 2 將這個來自電視ARC 的AC3 轉送去無線耳機擴大機時, 卻只剩下兩聲道
我懷疑是否RX-V685把來自ARC的聲音降級成2聲道輸出給HDMI 2了~
我希望的是, 由耳機擴大機自行解碼環繞音效
說明書上找不到任何相關資訊
不知道有沒有前輩清楚這部分?
Multi-room Video with a Home Theater Revceiver
上面這個文章裡面提到:
Another potential problem with using the receiver's zone 2 audio outputs is that many home theater receivers will only output analog audio sources to a second zone. Only higher-end receivers can sync audio from zone 2 outputs with zone 2 video.
另外在一個討論區中,有人提到以下:
Note however, that if you watch the same source in both places, the main zone will be down mixed to 2CH stereo if that is the only audio signal that the 1st floor TV can receive.
不完全清楚是否就是你的情況,僅供參考。

oh...
這個敘述的確很像是我的問題~但也不知是否符合
因為我的耳機擴大機是接在擴大機的HDMI out 2, 不曉得是否就是這裡提及的 "Zone 2 audio", 因為擴大機有另一個功能是multi zone, 用的並不是HDMI out 2.

這點就不是很像我的狀況
因為main zone就是擴大機本身,接收來自電視ARC的環繞訊號,解碼是一定沒問題,而我的耳機擴大機本身支援各式環繞格式, 因此不會是這原因被擴大機down成2聲道

因為我的耳機擴大機是接在擴大機的HDMI out 2...(恕刪)
在上面連結的文章裡有提到:
Put your old receiver to good use
If you want even bigger sound, you could connect a spare receiver with a pair of speakers to the second TV. If your new multi-zone receiver is replacing an older model, this is a great way to get some use out of your old one.
(這句話 -->) Just a few multi-zone receivers can output multi-channel audio to a second zone. ...
給我的感覺是第二個 HDMI 輸出多聲道,並不是個理所當然的功能...
這段說明是用另一個擴大機來接在 Zone 2,
跟你接耳機擴大機是一樣的狀況。
