I built an 8 channel API-312 clone with a linear PSU inside the same chassis. It worked great but I’m starting to notice EMI in the channels closest to the PSU. I would like to swap out the toroidal for one of these:
3-Rail Switch Mode Power Supply +/-16v and +48v
I have read that switching PSU’s require high frequency noise filtering versus the low frequency filtering required for a linear PSU. Does anyone know what methods are commonly used to do this and does this apply only to the PSU or should filtering also be applied to the individual channels as well?
