Skin a not from the chair

The Panasonic was it because of its compact dimensions, the suitability as a foot for the TV and for the barely tolerable price.

The interior of the box is easy. HDMI cable into the correct socket on the TV, enable ARC there - done. The box comes with the TV on and off can be controlled by the volume control of the TV remote control and it finally produces a sufficiently loud sound.
So far, everything is fine.
The Box has Fresh unpacked, as the factory settings now obviously inevitable, strong bass-heavy sound and roars and rumbles neatly in front of him. Unfortunately, there is no equalizer or something, but individual sound parameters are hidden behind marketing cryptic names and you have to try around for quite a while, until you have a less bassy setting with clear dialog found.
Unfortunately, the sound is generally not very intoxicating and can compete in any way with the playback on a stereo. Since the actual TV sounds better, but just too quiet.
That is why only three points.
