Only one flaw .....

I'll take it straight from the start - The vulnerability of the system are the microphones. Specifically, the radio microphone rushes really very strong. Although you can - if you open the battery compartment - with a small Phillips screwdriver to turn the Gain knob down a bit, but that's not really something. That is also the loss of a star in the rating.

Sound:
Unfortunately, there is to the system is not really a description. The included booklet is limited only to the labeling of the components. So first you live a while with the default sound to you below:
SET UP
> AUDIO
> EQ settings
the system missed an equalizer. (See photo) The stored presets are likely to cover almost every area of ​​music and the sound values ​​really on.
However, the EQ in only when USB and DVD / CD. Audio inputs are not considered.

There are to two remote controls. A small remote control for the video area and a large remote control for audio applications.
Unfortunately, the signal of the large remote control also controls the same time with the video display. If you then press a loud and in consequence the system displays Chinese ..... well ...
I taped the infrared sensor of the video displays with a small black tape. Is better that way.
The other sensor is located on the CD display. So there are two IR sensors.

One tip: If you plays music from USB flash drive or CD / DVD, it makes sense to adjust the volume to 50% to 70% down. In this way, the actual volume control does not respond so sensitively.

If one has all the inputs with signals, you can actually play all at once. So it is nice to mix into each other on the system even.
Anyone wishing to use the Speekerausgange must use powered speakers for it. the blank connected speaker says no Mux.

The display is a nice "nice to have" Of course it is not the best. Iogisch ... somewhere has to come from the price. But the screen is really great for the operation of the plant. Video are well reproduced. Who operates the plant on the battery can simply turn off the display. The operation of the system simply continues.

Important Note: The USB port is no folder again. But what in this form is common. For a complex music collection I would anyway always a notebook or Tablet suggest
During USB playback you can indeed go into the setup - but the menu item "Preference" is not selectable. Only when the playback is stopped, you can control the point.

So: That should have been first for the first ....
