PAC® Programmable Universal Low-Voltage Trigger Module, TR4

The TR4 Universal Trigger Module from PAC® Audio accepts a voltage as low as low as 0.8 volts then provides a 12 volt turn-on lead with a 1-second delay to turn on an amp or subwoofer in your car audio system. The 1-second delay eliminates pops. This accessory can be used to provide a delayed turn-on signal for virtually any installation need. The TR4 turn-on trigger can also provide remote startup for multiple amps or power antennas in a car and is also compatible with most amp installations where a remote is needed.
