I'd like my Samson sub amp to switch on and off with my receiver, but I can't plug it into the receiver power outlets because of its power requirements. Does anyone know of a device that would let me switch power from a separate outlet to the Samson based on the power going to it from the switched outlet on a receiver? I envision a box with an outlet on it the Samson power cord would plug into. This box would then plug into the power outlet on the receiver and into a separate wall outlet. When the switched outlet of the receiver had power, the box would switch on power from the wall outlet to the Samson. When the receiver turned off, it would cut power to the Samson. Are there any other ways to accomplish this? Thanks!
