Hi all,
I'm at a loss to figure out what's wrong with my Hypex NC500mp build but I'm not getting any sound from it. I have a balanced input that I've verified works fine through my Crown D75 but when I swap in the NC500MP I get nothing. These units have the built in power supply and I"ve checked and rechecked the connections I've attached a picture of my test build and here is the data sheet Hypex NC500MP data sheet
I have 120v at the power input and I hear an audible click when the amp turns on. The amp generates a bit of heat when left on but isn't hot at all. Am I correct to assume that if the unit triggered one of the protection circuits it would not get hot at all? I don't measure any DC on the input but I do see -4.6v on the speaker output with no source connected. Does that indicate a problem? Any ideas where I should look next?
Thanks for the help
Jim
