Hello guys,
I am working on a Crest X-Eight Console (Originally a live console) to build a studio mixing setup around it. I want to add a better Monitor controlling module, that includes a microcontroller and relay switching. I want to power them from the console PSU. Now I would like some advices If the digital circuitry might induce noise into the analog part. The desk already has some digital controlling, so there is a digital ground.
The power rails look like this:
+18 V
-18 V
+12 V (They make 5V from this rail for the digital part, see picture) but also used for analog Op-Amps
+48 V
Now I also need 5V, but the 5V in the desk isn't easy to access. I already brought a cable out with all the PSU Rails, so I need to make 5V from the 12V Rail. I thought a regulator might get pretty hot when powering some relays, so what do you think about these Step-Down Converters? Is that crap?
