OK sounds like an universal switcher.... The first one of those I did (last century) was used in a higher end monitor mixer, that was low volume and higher priced so it made more sense. Now I suspect the cost of a universal PS are much lower, probably low enough to standardize on just one PS for all products.
For some inside baseball, when I was researching the desirability of using universal PS in Peavey products some of the international distributors didn't like the idea... Especially the distributor for South America who had both 120V and 240V countries inside his territory. He was worried about gray market transhipping, where say a big dealer in a 120V country could sell goods unofficially into the 240V country and vice-versa harming the integrity of the different dealer's exclusive territories.
I am afraid to even think about how tangled up it is now...
When we started making drums in China, we discovered that some had walked out the factory back door and ended up in Italy of all countries... Trust but verify or in other words don't trust.
