| As you can probably figure out by the links below I have a vision. I want my audio-system connected to my sources to be able to reproduce whatever the producer intended for me to hear.
| |
|
| |
|
| The are several step to the process. Most are easy to fix with cash and moderate WAF. In order to increase WAF and reduce cash I have been investigating some other possibilities. | | The general idea is to put some stuff about the Audio-hardware of the Dune BD Prime here: |

| Some links to stuff that I'm involved/interested in:
| | The audio section of the BD Prime is relatively simple. |
| | 4 parallel stereo DACs make up the audio from signals passed from the main board. |

Overview
The audio section of the BD Prime is relatively simple.
4 parallel stereo DACs make up the audio from signals passed from the main board.
Hardware
Signals to DAC-board
And the Audio DAC-board itself
