Hi all. I have to admit up front that I know staggeringly little about wiring, electricity, etc. I have soldered before, but just to connect some insulated wires together... I also know that I need a sanity check before trying something like this out...
I have a particular piece of audio gear, an XLR converter for some microphones that I use to record test sessions - one of these: http://www.beachtek.com/dxa6vu.html
It takes 9v batteries for the phantom power that goes to the microphones, but the problem is that it goes through them like a kid in a candy shop. I get about 2.5 hours out of a single battery when powering two microphones. With the amount of sessions I do, this is becoming expensive. And if I forget to change the battery, it inevitably dies in the middle of the next session.
As the converter does not have a plug for a power adapter, I was thinking about making one myself. This is the sanity check part as the device costs about $400 to import from the US (I'm in Australia) or almost $800 to buy here.
I was looking for something that I could just buy outright, but I can't seem to find anything... Probably a bit too niche of a need. So I came up with the following plan instead:
1) Get a 9v AC/DC wall adapter... they have one there that is 9v, 500mA output only with the exchangable tips that you can flip around + and - on...
2) Get a pack of the little leads that you plug a 9v battery into, they come with the red and black wires already attached...
3) Get a connector from one of the bins that you can unscrew to attach the 9v connector wires to... One that fits one of the exchangable tips in the package of course...
4) Connect the 9v leads to the connector, keeping the polarity the right way around (I'm going with the guess that this does matter) and plug it into the 9v AC/DC adapter...
5) Somehow get the 9v connector in the right position in the device (it goes into a little sliding tray), plug it into the wall and turn it on...
6) No expensive smelling smoke...
In my head this works. But I also don't know this stuff as well as you folks here do - so I'm probably missing something terribly obvious which would result in a bad day.
Can anyone let me know if this will work, or if I have to adjust it in some way? I'm also interested in what I might be able to do to test it before I plug it into expensive equipment...
Thanks much for your time.
