Original guide adapted from a post by citrus3000psi.
This guide assumes the DAC in your Dreamcast is a PCM1725.
Required Materials
- Pep Audio 1.2 PCB
- If using TOSLINK:
- TX178A (TOSLINK port)
- TOSLINK PCB by citrus3000psi.
- If not using a TOSLINK port, you will need your own jack.
Installation
- On the top of the motherboard, solder wires from these four legs on the DAC to the matching pads on the Pep Audio board.
DATAon motherboard toDATon Pep Audio PCB (notDATA!).BCKon motherboard toBCon Pep Audio PCB.LRCKon motherboard toLRCon Pep Audio PCB.MCLKon motherboard toMCon Pep Audio PCB.+5on motherboard to5Von Pep Audio PCB.GNDon motherboard toGNDon Pep Audio PCB.
- Connect the output jack:
- If using a TOSLINK port, connect +5V and GND to it. Also connect
DATA(notDAT!) on the Pep Audio PCB to theInon the TOSLINK PCB. - If using your own SPDIF port, connect
DATAon the Pep Audio PCB to the data pin and GND to GND.
- If using a TOSLINK port, connect +5V and GND to it. Also connect
- Partially reassemble, snaking the board past the metal shield as shown below:
- Mount the output jack on the case. Example completed install:
