Hi Diki.

Your just assuming they remove the switch which is not the case at all. There is an automatic switch inside and there is a cross bar system in place that also prevents popping of the speakers and overload.

The Switch sounds like some sort of magnet relay and there is a second or so delay from the time you supply power before the internal switch kicks in and before my 9024's power up.

It's a really good system and something that's very popular in Recording Studio's. Many Rack Mountable Power Conditioners offer this very same function. You just plug into them and leave everything you own switched on. When you switch on the Rack Strip, it then powers up everything in one go.

Very cool feature that eliminates the risk of a surge when powering up lots of things at the same time.

Regards
James
