It is not trs powerful, it is not possible for it to do the 50 W ad.
At low, it is limited by the size of the speaker.
I would say it is not suitable for playing music. It can connect a microphone and use it for amplification in a small room (<40 people) or even better, as fixed in a language classroom, for example. The teacher no longer has that connect the mp3 to disseminate audio clip. For this purpose, the price can be justified, but even when it is not given (133 Thomann).
