John, Because after power off, the fans are powered by the charge in the KPA500 capacitors discharging, I do not think that is a requirement - but not a bad idea in any case. 73, Don W3FPR On 2/1/2017 7:53 PM, John Marvin wrote: I know this thread is supposed to be closed now, and

I know this thread is supposed to be closed now, and hopefully this would be obvious, but you should also wait for the fans to stop before "pulling the plug". You should always turn the KPA500 off with the switch (or the KPA utility) first, wait for the fans to stop, then you can use the back

It's been that way with PC's and Mac's for 15 years. Your PC is not truly "off" when you hit the power switch. That is the ATX specification. To start a PC all that happens is the shorting of two pins on the motherboard with the switch. There is power on the motherboard until you reach behind

Dave, Perhaps you want to turn on your amp manually each time. But what you may have missed is that 7 watts is doing more than just detecting whether the power switch on the front is used or not. When the KPA500 is "off" the RS-232 connection on the back is still live, and there is a

"Incredibly wasteful" - Seems like a little bit of an overstatement. That's only 4.968 Kilowatt-Hours a month assuming it is idling 24/7 for 30 days. For me, that'd be about $0.49 in electricity. At $0.22 a KW-Hr, it'd still be under a buck per month. If this is still "incredibly wasteful"

Leave it to an environmentalist (I'll spare the engineers) to advocate the spending of thousands of dollars in redesigning something that can be fixed with a quick trip to a local hardware store for a $25 (or less) master kill-switch. Kent, K9ZTV There is one thing about the way it works

While without reference to quantities I certainly agree with the sentiment, but to be focused on a night light level power is kind of like swatting at gnats while pidgeons are flying around in the kitchen. Does your attic insulation need replacing. Are all of the light fixtures in your house

I recently added a KPA500 kit for my home station. It went together just fine, and overall I love it. There is one thing about the way it works that bugs the engineer and environmentalist in me. Before I bought the PA, I thought I'd be able to turn it on/off entirely using the ON button on
