[QUOTE="John Roberts, post: 43108, member: 126"] Re: Question about headroom with dj mixers While this seems to be a pretty common perception, I am not aware of any justification or basis for this belief based on the technology of switching PS. Transformers do not store** power supply energy, capacitors do. Capacitors can be sized marginally for either design approach Funny the 2450 does not seem like an old iron design to me... more like the newer 2U stuff. It's good to know there is a market for heavy old iron... :-) I wonder if there's a similar market somewhere for my old 286 PC? JR ** transformers do transiently convert electrical energy into a magnetic flux in the primary, then back to electrical energy in the secondary, but this magnetic flux is not persistent and the conversion process occurs on a time scale far too short to be meaningful to bass notes.
