About the PAC TR-4 Trigger Module

Buck Pomerantz

Manage your 12-volt system's on/off switching

PAC's TR-4 Trigger Module uses a low-voltage trigger circuit — as low as 0.8 volts — to switch on its output circuit so that a 12-volt signal can turn on all your system's processors and amplifiers. The trigger is sensitive enough to sense even the DC offset in a receiver's output signal, so you can use this electronic relay to turn on your system without needing to run a wire to the fuse box. The TR-4 features a 1-second delay when switched on, to eliminate any potentially damaging amplifier turn-on pops or crackles.

Note: This is a low-current, 2-amp, electronic component suitable for switching a trigger circuit. It should never be used directly on an amplifier or receiver's power wire. Warranty: 1 year.

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.
