I had been looking for a controlled via USB socket, as a "substitute" that my new A / V receiver has not switched AC outputs more. But this has been hiding on the back a USB port, which is actually intended for a Bluetooth dongle and is switched. This works great with the bar! If the receiver is concerned, the outlet peripherals (DVD, CD, console) to and well on after a few seconds with a little relay-click again. When switching capacity are given something about 2000W. VDE GS or is not it, but at least one CE. The bar looks neat processed and even comes with a small "operating instructions".
