Did you already submit a support ticket? Generally support questions should be sent there — we don’t check forum posts frequently. When measuring voltage, make sure you are measuring between COM and a zone port (it’s a common mistake to measure from GND to a zone port). Also, since this is DC-powered controller, you should measure DC voltage, not AC. I doubt if the controller is broken — we double test every controller before shipping and the chance of DOA should be very small.
