次世代訊源PK賽及深入分析

[john925]

750D可以顯示96、192及176.4，不能顯示的原因出在使用電腦輸入數位訊號，數位資料流會與其"header information"一起變化，而Headers有3種：Proaudio、Consumer Audio與Pro-sumer

如果沒有這3種，那麼750D就不能Lock，不過好處是有軔體可以升級了
Do you have access to a RS-232 (DB9) to USB cable ?
這句話有人可以幫我翻嗎？是說我用RS-232接到USB? => ???

PS 所我我猜Embla數位輸出沒有Proaudio、Consumer Audio或Pro-sumer的Header，因此沒辦法Lock....:|

======================

The 750D is capable of displaying 96kHz, 192kHz and even 176.4kHz.
This is probably happening because your are feeding the digital signal
from a computer. The reason is simple - digital data streams vary with
respect to where and how "header information" is used - this header
ONLY contains descriptive information about the data stream.
There are actually 3 different types the headers - proaudio, consumer
audio, and pro-sumer (a mix between pro and consumer).

If you were not getting any audio, then there would be a problem - i.e.
the 750D cannot lock onto input digital signal ...

The good news is there will be a firmware update to the 750D available
very soon that fixes this problem. Do you have access to a RS-232 (DB9)
to USB cable ?

可能是要用這條RS-232-USB線，接電腦做韌體更新吧！:^)

好像還真的有這種線耶，我來買一條...

今天試接USB

[Leo Yeh]

電腦自動安裝，Plug and Play，也不需要設定

[Leo Yeh]

錯誤示範將電腦放在750D上 (拍照方便用)
新的SONY電腦不在家，先用老戰友ACER試

[Leo Yeh]

顯示在48kHz，原廠有說USB晶片接收後，其數位會輸出到M-AJiC32進行處理
