I bought a Harmon Kardon avr125 and it has two outlets on the back, one is 100w unswitched and the otehr is 50w switched. Can anyone tell me what that means? thanks.

Anything you plug into the switched outlet will turn on and off with the power button on the receiver. Anything you plug into the unswitched power outlet will see power all the time.

depending on which type of unswitched connector it is (I have an HK receiver too) you usually plug your CD player/DVD player/etc. into the switched and the TV into the other (if you trust the reciever). It's conveinent to have the TV switch a receiver, but some of them completely cut power so every time you turn it on you have to reset everything...and that's annoying.

I remember have a cable box a while ago...and it switched the TV with an outlet, but the TV never lost total power (i.e. I never had to reset the time). I wonder if there is a difference

No, no, no, no, no. Don't go plugging a television into a receiver accessory outlet. Any monitor is going to exceed the whole 0.8 or 0.4 amp rating of the outlet.

Most definetly a TV or Monitor should have it's own outlet not one on a receiver. They draw a lot of power on start up. Those switched and unswitched connections are ok for plugging in EQ devices or DVD, Tape decks and CD playrs but thats about it. I don't use them I plug everything up into power strips.

I've never actually plugged my TV into the receiver (b/c I don't trust it)....but here's the question....

do the switched outlets provide any power when they are "off"? I rememeber an old cable box that seemed to provide enough power for the TV To not lose it's memory....

I guess it would depend on the make.

I can plug in a telsa coil to the switched outlet on my receiver.

Good for you! I can plug a tesla coil into the non-switched outlet on mine.

I'd imagine most televisions have a battery that will last at least a couple days. Otherwise the outlet wasn't switched (or you always left the cable box on).

Well since the tesla coil obviously requires AC power, I like to shut it off when I am not listening to lite jazz on my receiver.

My reciever specifically says not to plug in a TV or monitor, would a ps2 be ok to plug in?

Yes.
