How to incorporate Rakk DAC2 to Mood Indigo pre

98.234.230.223

I have a Mood Indigo pre and would like to incorporate a Rakk DAC2 to the existing chassis. Any advise on where to begin is appreciated.
Thanks in advance.

Your first decision is: do you want to upgrade the electronics in the Mood Indigo? John Tracy chose to do so and his unit is shown here: http://www.raleighaudio.com/tracy.htm John used the Mark I RAKK dac 12V power supply and stood it on edge. The Mark II draws more current than the Mark I so its power supply is physically larger, precluding setting it on edge. I don’t know if there is room to lay it flat, you would have to verify that. You would also need a separate 12V control power supply.

Assuming that you don’t want to upgrade the electronics, you would need to use a Passive Output board for the RAKK dac. The existing 12V supply may have enough juice to run the RAKK dac; at the very least, you would need to remove the HV bias on the 12V common and reference it to ground. I have no idea how it would sound and would recommend using the RAKK dac Mark II 12V power supply for the RAKK dac and leaving the existing 12V supply for control and filaments.

In any event, whichever way you choose to go, your first step is to make paper templates of all of the parts and shuffle them to see how you want to lay out the project.

  Hi, I just wanted to add that the RAKK DAC I power supply that I used was modified with a larger PS transformer and extra filter caps as seen in photo. The DAC does occasionally loose lock and experience drop-outs. This could be due to loss of regulation in the shunt regulator used with the original PS. The latest series regualated PS could be implimented on two perf-boards and be mounted vertically as I did. The circuit is not too complex and forgoing the PC board would not be too much of a pain. -JT

    Good point John, thanks for sharing it. I was wondering what those extra capacitors on the perf board were for - now I know.
