Locate the control panel for the Audiobahn A275HCX amplifier. This control panel is where the main power source is attached. Next to the fuse, there is a small (less than 1/4 inch) red button with tiny writing above it that says, "Reset." Push in the "Reset" button using a safety pin. The button is too small to push with fingers; this is done as a precaution to keep users from accidentally resetting it.

Replace the fuse. Remove the fuse, this automatically stops the unit from receiving power. Replace the fuse with a new one. Fuses are cheap and replacing is good maintenance. If a replacement fuse can't be found, put the old one back in to restore the connection. The brief loss of power can reset the unit.
