From the little brother of this device I have a four piece. Now I ordered the big brother for the first time. This speaker convinced me even more, as the small edition. The sound is better and louder. Two wireless microphones are better than one. This unit also has antennas for the microphones. The extra supply via 12V is another bonus point. A screw allows the tripod adapter lock the missing in the smaller version. First use was a discussion in which it arrived only on language. Worked fine. Second operation was a small party with 30 people reported and a laptop as a source. Were somehow 100. No problem for the speaker of the 30 people. He stood on a tripod. The thing turned louder and increases the tripod slightly. Worked behaviourless The third application was then an event in which I assumed the slots on the mixer drohten.Ich the presenters of the evening have had moderate over the loudspeaker with the radio microphones. The speaker then served as a monitor of the language. Through the Mixed out I needed only one stereo channel on the mixer. The subsequent after-show party went solely on the box. All The Best. As monitor, sports ground PA, for solo entertainers and for smaller events, this product is ideally suited. Also works on Bluethooth and you can take the part also.
