If you don't want to go through the process of converting AC to DC, run a BlueRail 5 amp board and Tsunami 4400 sound card (not the Blunami 4408) using the Blunami app. Only down side is you do not get the menus @BOB WALKER mentions above. You have to know your CVs. But the BlueRail 5 amp board supports AC track power.
