A shortcircuit overload to the power supply can occur if the central pin in the coaxial cable connection to the receiver is bent or crushed against the connector during installation; it can also occur any time the user disconnects the source from the receiver.
Solution: PolySwitch devices.
PolySwitch devices help limit the flow of dangerously high currents during fault conditions and reset back to normal operating mode once the fault condition is removed.
