Running ac and dc power together

Greetings everyone, noob here from downunder.

I have a question about a small installation I am helping a friend with.

It's in a very cramped space with no power outlet so we decided to use components run from plugpacks located in the next room with leads going through the wall cavity as one bundle.

All good but now I realise that some of these plug packs are ac and some dc, but all low voltage.

Finally to my question - could there be interference from the mix of ac and dc lines particularly for the turntable and phono box?

If this was easy I would just try it out but the installation really is a nightmare plus the walls are asbestos.

Thanks for looking, mouse
