Have a linear supply 800va transformer with 83v after rectifier, 12v smps 5a for the signal power. Have my se input to hot and cold tied to agrnd. Cannot get any sound. Do I need to have mute or standby connected. This is on a Icepower 500a hanger module. Purchased from Parts Expresss and tech support is no help. Im at a loss as to why its not working. Have my main power on + on the cap and black wire to neg on the cap. Anyone with experience wiring these willing to help would be greatly appreciated.
