RuneAudio Forum

I currently use runeaudio with a rasperry pi and some active speakers in my sons room to play audiobooks at night.

I've decided to try creating a 1 box solution.

The only issue I have is I'd like to have just a single lead going to the box, but I need to power the TA2020 amp AND the raspberry pi, so what I think I would need is something that could provide 5a at 12v for the amp and 2a at 5v for the pi, does such a thing exist? I guess the simple (but crappy) alternative would be to put an extension lead inside the box and just run 2 seperate plugs off it.

Does anybody have any suggestions?

Would something like: http://www.dx.com/p/t60-5-12-12v-5a-5v- ... U981fnF-So work?

If it would, would I need to do something to reduce the 8a from the 5v supply?

This power supply contain inverter and inverter is not good with use DAC, exception for specialy power supply with hash voltage at 300Khz

But for Digi output this powersupply is good

Well to begin with audio will just be from the built in jack on the pi, but eventually I would probably add a DAC, so if that supply is no good for that are there any other options?

Would using something like http://www.monacor.co.uk/products/carfi ... nr/212420/ between the pi and amp help at all?

I've build a System like this and now i've got some interference noise.
Is there any solution for killing them? Maybe with a cap?
