TR-4

The PAC TR-4 Low-Voltage Remote Turn-On Trigger is designed to generate a reliable 12-volt remote turn-on output from low-voltage audio signals. This compact module is the perfect solution for activating aftermarket amplifiers, signal processors, or other audio components when installing systems that do not provide a traditional remote turn-on lead.

The TR-4 senses low-voltage speaker or audio signals and automatically generates a clean 12V remote output, eliminating turn-on pops and ensuring connected devices power up only when needed. Its compact size and simple installation make it ideal for factory radio integration, OEM amplifier bypass installations, and modern vehicle audio upgrades.
