Unfortunately, the device is kept very minimalistic on these features also. Equalizer function is only available in the form of Treble / Bass value. On the rear panel there is NO connection options. Anyone who wants to connect an external audio source must do that via the front jack. Pretty ugly as a permanent solution.
In addition, one should look at the device before buying exactly. In operation light on the front panel behind the clear plastic surface plastic strange formations in blue. I like that at all, and only through the complete dimming the entire front can this blue lights off.
Especially bad is the quality and the sound of the supplied boxes. From which comes a puny speaker cables and they do not have clamps or similar where you could connect your own cable. The speaker cord is puny concerns what length and diameter. Will buy myself on occasion definitely better boxing! Until then I push the one-dimensional sound on the speakers.
Actually I'm not satisfied with the purchase. Comparable products of a quality brand can easily cost three times and more. However, I recommend each buyer the unit to look at closely. Namely, just exactly what it says. Who has speculated on a stereo input at the back of bad luck. Also suitable middle class boxing you can not forget to order if one is a little more demanding on the sound quality. Speakers JBL Control One can I highly recommend.
