...powered. Tech Help? This is a little floor box to provide phantom power to condensor mics. the piece of equipment is only like $40, but the mics it will power will be $200 and up,so "maybe" answers just dont help unfortunately :/
Ok, to start. I have a wall wart for it.
Input: 120v 60Hz 6W
Output: 9VDC 300mA
+ |----{o-----| - (polarity, obviously)
My question. Can I make little piece of equipment run on a 9volt battery? How long would it last??
Would it be possible to set it up to run off a 9 volt battery, while keeping it possible to plug it in (if I run out of batteries)?
I thought about just soldering in the + and - wires for a 9 volt battery inside the casing, at the same point the wall wart enters the box.
Theoriticly, (if its as simple as just putting a 9 volt battery in) I would be able to plug it in and have it work. Unplug it and add a battery and it would work. But what would happen if I did all this, and I left a battery in it, then plugged it in. Would it zap my equipment? Logic tells me so. Is there a way to make it idiot proof?
