This is an excellent remote power controller that has a power trigger which you can plug into your preamp and upon turning on the preamp, will turn on the outlets and thus whatever component is plugged into that outlet. Its a very useful feature where you don’t need to turn on the rest of the units and can turn them on by just turning on one component, in this case, the preamp. The four switched outlets will only work when the trigger is connected. It also offers AC filtration and is not current limiting.
Cosmetically, the unit looks good. Some minor scuff marks here and there but nothing major. Unit will be securely packed for safe shipping.
