I have an audio mixer which can run on two 9V batteries in series. I'd like to run it off a single 12V supply.
- Can I use two 12V-9V DC-DC converters both running off a 12V battery?
- Will the connection to the 12V battery short the 9V series connection?
The mixer is a Behringer 1002b, the AC input adapter is 16V and 3V.
When I test with batteries I get 18V across the power switch
