You can improve X10 performance and conveniently control X10 modules placed on different phases of your home's electrical system by installing the X10 PRO Wired-In Coupler Repeater Amplifier. The coupler/repeater serves as a signal-bridge across split-phase and 3-phase electrical systems, repeating X10 signals from one phase to another.
Devices such as TVs, computer equipment, or anything with a complex power supply can absorb X10 signals. Even if you have a smaller home, but you use a great number of electronic devices, then installing the X10 coupler repeater is a great way to ensure maximum functionality of your X10 system.
