Features
Low Voltage Trigger Module: The PAC TR4 module is designed to monitor low-voltage signal and turn on once the signal rises to above 0.8V DC. This makes the TR4 ideal for turning on an aftermarket amplifier and/or other 12-volt accessory when only a lower voltage signal or speaker wire is available. The module supplies a +12V/2A output which can easily drive multiple amplifiers and/or a power antenna. The TR4 is equipped with a 1-second delay to prevent turn-on noise/pop.
