幾經辛苦終於整好隻線電,有兩組5v比raspberry pi,9v比router,
咁駁好router 同raspberry開聲又嚇一跳三隻字,干,硬,化{:6_200:}
當中攪左小小調整,將router拔走改善左好多,
無咁干,同化,(可能係干擾影響),
跟住修改退耦電容,本身用隻RIFA,
膽機好多時用到,但係唔夾線電,
換上"東和"再加WIMA再試係佢啦!!{:6_181:}
結像更出,動態更大,人聲厚度適中好有好有感情,
好多時由"開關式"電源轉做"線性"電源音效有機會過厚同暗,
現在剛剛好亦實現當初使用LAPT高頻線性放大功率管做輸出既想法,
當然CLC濾波都要記一功啦,連台灣KECES都用就知有幾堅,{:6_174:}
-----警告行MPD裝置線電不能與ROUTER共用-----------
-----其實我已經係兩組獨立都唔掂,一組個D自己捻-----
再講多次人聲真係好靚 IN MY LOW FI SYSTEM{:6_193:}
唔用線電係你既損失,記得搵隻靚o野{:6_142:}
又一高手 {:6_193:} 多謝師兄加分,
純粹自娛玩下,並非什麼高手,師兄過獎{:6_211:} {:6_193:}厲害! Raspberry Pi is simple and beautiful.Did you try playing DXD or DSD128 and see if Raspberry Pi CPU fast enough to handle high resolution records?Thanks. odysseyhk 發表於 2013-8-6 22:08 static/image/common/back.gif

picoreplayer 只試到24/192,其他唔清楚{:6_123:} zoneaudio 發表於 2013-8-6 22:16 static/image/common/back.gif

Good to hear 24/192 working great. Let me know if I can help you test DSD and DXD. 漏左小小秘技未講,線電不能裝置要5V就比5V,
要多小小例如5.2-5.5,因為要預埋線材既損耗,
好似Raspberry Pi仲要過粒限流fuse(圖)
如果正正5V去到A點得番4.8V左右,
再到B點已經是4.5V足足低左10%,
而圖紙好清楚標示B點是5V

C-Hing, this's a top secret !it worth for $5,000. {:6_193:} 估唔到支 fuse 可以降到 0.3V !!!
