I ordered this amp set / Karaoke Christmas and after having profited well, I judge coherent, functional and of good quality. Wired microphones are heavy and provide a quality feel. The wire length is sufficient and the on / off switch is convenient and well located. The main housing can accommodate two external sources cinch and has a front USB port for direct playback of a USB key: practical and well thought out with the navigation buttons located just above. The microphones / outside sources settings are soft and very pleasant to deal with, I just wish that the input level of external sources is a little weak, not gain adjustment to compensate. Only son to link the speakers are a little weak, I would have appreciated a slightly larger diameter and length is limited if one wishes to deport them as I did. The connectors on the speakers benefit from being changed; they are a bit lighter. I said that I also use this package to disseminate a video player audio when I watch a film that is excellent, the bass is well rendered it's a pleasure! Finally I note a small flaw: no LED indicating the operation of the device (a switch, it is quickly forgotten ...).
In conclusion, I recommend this set for a successful karaoke experience and quite lovely!
