I hope this is the correct place to ask this question. I recently purchased the O2 amp and have been confused by the power supply it requires. It needs AC power at about 15v and it seems very rare to have an electronic device that requires AC rather than DC (I've never had one anyway). So, first question,
Why would this device be designed to use AC power input rather than DC like all my other devices?
I've been thinking about this, then realized that when it runs off the 9v batteries it is running of of DC power, since the batteries are DC. So second question,
How does it use DC power from the batteries if it requires AC for the plug?
I obviously don't know a lot about electronics. It could be that the amp converts the batteries to AC somehow, but that doesn't answer the first question. Any help would be appreciated as I'll be thinking about this and wondering until I find the answer
