The TRIGOFF is a device designed to delay the deactivation of an amplifier or power antenna when the radio is turned off. This will eliminate the turn-off 'pop' that can sometimes be present when amplifiers are added to existing sound systems. If you hear a loud 'pop' through your sound system when you turn the system off, you will need this device.
The TRIGOFF is an electronic triggering device encased in a small plastic enclosure measuring 3 inches X 1-1/4 inches. Color-coded wires are used for the input and output connections.
