用LPCM會變咗碟機解碼

chanwt

又有問題呀!
我用BDP同軸 > MD10 (DAC) > intergrated  amp 聽歌.

看完Ｃ Ｈing 教路, 將BDP同軸輸出set 去 bitstream, 部DAC 無晒聲出!!

set 返 LPCM 又無事, 究竟乜事???

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???

since no ching wanna clarify my query.
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 conveyed  by b bitstream signal ...??

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

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!

chanwt

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。
