Hi forumites, hope someone can help.
I recently bought this Mono, 500W Class D amp module along with the AA-AA11117 volume control.
Im running it off a pair of Laptop supplies in series to get 39v. I also have a preamp that is working OK, but when I apply power to power amp all i get is a constant single tone about 400-450Hz, Disconnecting input does nothing. I have only ran it for a few seconds so i dont destroy it although its not very loud.
Any suggestions?
