Yes, the enclosure will have plenty of other 'computer'-type boards in it - DLCP, DLCP control, and a couple of switch mode supplies, but I guess the difference is that those are designed by Hypex to be good with audio, whereas the RPi isn't. But I can easily test it out and decide whether there's anything audible.
Interference issues aside, has anyone experimented with a hub on the USB input?
They all have to pass the same EMF tests. The processor used by the RPi uses tecniques such as clock frequency spreading to minimize emissions (as it is used in mobile phones and other applications sensitive to EM noise).
My pack of 5 push buttons arrived this morning, so here's what I envisaged for the RPi control panel - a mirror image of the DLCP control button layout. The central button is missing for now as the buttons come in packs of 5, and for testing purposes the function of that button will be taken by the push button function of a rotary encoder that I'm experimenting with.
I ordered these initially to use for measuring purposes to design the DLCP face plate, but between ordering them and receiving them I began to play with controlling the RPi via push buttons, and now I quite like the idea of having a physical interface in addition to all the software control options. The button caps come in a variety of colours - I bought yellow just for something different, but I may go for orange as I'm planning to screen print a nice big colour version of the orange Hypex 'waveform' logo on the faceplate.

An externally hosted image should be here but it was not working when we last tested it.
I'd be very surprised if there was any noise within the audio spectrum emitted from a Raspberry Pi. Same with good switch mode power supplies. Noise above 100KHz will have no impact on audio performance.
Well it says in the post
Ah, so playing "10 questions", are we? What is the prize?
Here come the 3 first ones...
So it is two different pictures of a Meanwell RS15-5 power supply. From the output of the power supply I assume? What is the difference between the two pictures? And what is the relevance to the discussion?
