I'm going to start a project on a controlling speaker array and I need to control the signal's polarity fed into each speaker. I want to make a 'router' or 'controller' to make it easy, so I don't have to change all the wiring when I want to change the polarity distribution.
I googled some keywords and found H-bridge IC. But I'm not sure if that is compatible with AC signal. Besides, I'm afraid of controller size, because I need the controller for speaker ARRAY including many speakers, at least 9.
So, anyone who has an idea how can I solve the problem would be appreciated, very much. Now I'm thinking about kind of multi-channel connector that I can assign the signal to each port. (e.g., (+) signal to 1,3 port and (-) signal to 2,4 port)
Thanks for reading, I'm waiting for the advice. Have a nice day!
