Operate this device in a room with 12 sqm. Playback is very versatile in this investment and the setting, sound volume and sound! The device looks in product terms of good. Receive the signals at the moment on tv points, but also have a good Empangslage. Cable connection is also possible thanks to the aerial socket, but I need to retest. Commissioning and adjustment of the channels is simple and easy to learn for everyone! For that price, quality and appearance of this plant is perfectly okay! I am very happy with it and can only recommend it!
