Have the system and sent to get set up, the following shortcomings have come to light: - The calibration via Microphone not been possible - The subwoofer is buzzing, even without sound - The ARC connection to TV no incoming beam of the sound signal from the TV was from possible even though all settings were made accordingly. I assume that this is a Produktfehrler. I send back the item and give the system a new opportunity in the form of a reappointment. What has also struck me: the amplifier has a trigger connector, the subwoofer is not. On cable trigger connector at both ends there - I do not know if this should be so ....
