成部機共要四組電壓
+5V for Digital Video board
+15V for BD drive motor
+15V for DAC analog board
-15V for DAC analog board
(After the LM317 and LM337, the output for Op-amp is +/- 12V, therefore you can use AD8620)
電流量度參數:
3 組USB 不接任何野
衹播放Blu Ray 碟
5V for video board--> 1.5A (no HDMI connected, just BD playback)
+15V for BD drive --> 0.2A normal, 1A peak(播播下突然按Stop)
+15V for Analog DAC board (入面再有LM317 轉+5V)--> 0.2A
-15V for Analog DAC board--> 0.02A
Estimated power consumption:
5V for video board 5x2-3A = 10W-15W
5V for USB port x 3, 5x0.5Ax3=7.5W
+15V for BD drive (Avg current), 15V x 0.5A = 7.5W
+15V for Analog audio, 15V x 0.2A = 3W
-15V for Analog audio, 15V x 0.02A = 0.3W
Total loading power = 10W+7.5W+7.5W+3W+0.3W = 28.3W
Assume efficiency of the switching mode power supply is 75%, then
28.3W / 0.75 = 37.7W input power, which is close to OPPO provided figure of 35W power. 作者: bigboyhk 時間: 2012-11-29 00:24

有些是可以預告的:
開關電源, 你點摩都係開關電源, 除非.........……但犠牲了Standby power consumption.Audio Video 獨立R-Core
7.1音道解碼輸出, 如果閣下是用HDMI 作音頻輸出, 7.1 Analog 是浪費的, 不如………塞一個2.0靚DAC入去吧,再加埋TE8802 USB 輸入,再做踐格野,借TEAC 個software 來用, 可以玩DSD over PCM, Super Ram buffer for Audio playback( 就像PC的JRIVER 一樣), 這個要TE8802 硬件low level driver, 我當然知點改。
BDP-105 雖然有USB入, 但解吾解到DSD, DoP, Ram playback 仍然是未知知數。
