Why there are two power inputs?

The 5 V is for signaling ( which relay will be activated? ) the other one 12 V for relay supply. It goes to the relay supply.

There is a connector on the other end to allow multiple strips to connect. However the power supply and driver module will limit the number you can connect. Two shouldn't be a problem, but not more than three.

You can use either one, also the 2nd one can be used to extend power to another device.

Jay, I'm sorry but I don't understand your question. What do mean by a "second power supply"?

Theres a small Input button under the monitor next to the power button that lets you switch between your different inputs.

One is for power, another is for battery charging, and the last if for low battery.

They both need to be plugged in on the same circuit. If you have them both plugged in then throw the circuit breaker for that circuit they should both turn off. Just be careful of what else may be on that circuit. Hope that helps.

there is a US male (input) plug on the unit, and a US female (output) recepticle - makes no sense to use both at the same time - this unit is an adapter, not a transformer.

I am pretty certain you don't have to connect two loads. If required, you could wirenut both loads together and have both switches control the same load, then when you are programming it you can change the function of the switch.

You have two separate wire connectors for accessories instead of one. One switch for two items

For power it has one ground and one power. For the speaker out put it has 2 positive and 2 negative

Yes. 2 Power In, and 1 Power Out. Select A, B or Both inputs. Pretty simple switch.This is a good quality part- I was very satisfied.

That's correct. I am using four of these to power four Raspberry PIs. Yellow/Red are the 5V out side and Black/Red are the input side.

I wish one of them were passive and they sold them in pairs. Both are active, meaning 2 power supply.

there are two XLR-1/4" combo inputs infront and 2 L/R 1/4" outputs at the back

My guess is the second set acts as a backup unit for extended run time or if one circuit should happen to fail, the other will take over.

Both outlets turn on simultaneously. There is no separate control for each outlet.
