用LPCM會變咗碟機解碼 又有問題呀!
我用BDP同軸 > MD10 (DAC) > intergratedamp 聽歌.
看完Ｃ Ｈing 教路, 將BDP同軸輸出set 去 bitstream, 部DAC 無晒聲出!!{:1_334:}
set 返 LPCM 又無事, 究竟乜事???{:1_347:}
再者有d 明,如係 "碟機解碼" ,咁部DAC 做緊也嘢??
部DAC 上顯示 "MCP 44.1K" , 即係佢收緊 LMCP, 44.1k 嘅信號嗎? (因MD10的手冊很"垃圾", 只係講d 唔睇都明嘅野)
咁究竟係要點駁呢??? 又有問題呀!

I went online and check it out, it seems that LPCM is a digital signal and need a DAC to convert it to digital.
Bitstream is another digital signal but it is widely used for Dolby, DTS encoding and used for multi-channel.While I am not sure if a normally 2 channels CD signal can be conveyedby b bitstream signal ...??
用DAC聽歌?
It all depends on what kind of digital signal the DAC can handle.Philips 9500 recommends PCM output DTS signal if DAC cannot handle DTS- 發送自我的 iPhone 大板凳應用 回復 33# chanwt
首先bitstream唔使關閉,如果BDP用同軸出嘅就係DAC解碼;BDP用rca出嘅就係BDP解碼! Hmmm..thats all clear now!
So the statements ".....軸線會直出數碼信號,再比DAC行D/A,
用Bitstream....."AND"用LPCM會變咗碟機解碼.." were confusing and not totally right!
My MD10 cannot take bitstream signal so must be set to LPCM. otherwise there would be no output!
Thx. Bitstream係比你選擇用唔用BDP去解DTS同DD做PCM。CD本身已經係44.1kHz無壓縮PCM。
