I use this system since June 2007.
What is most significant is the purity of sound, ease of setting, the remote control system, and reduced feedback compared to a conventional system. Very significant, too, the ease of transport. Once a row, it does not take place.
This is somewhat detrimental, is the lack of stereo, but for use in stage, bar, which is fine, especially for a rock band and a major use for singing.
I tried many systems. The entries range often have a disastrous, and those with a good sound are expensive.
The value for money is excellent.
After the experiment, I am not at all disappointed. This system is ideal for sound to a single voice or instrument, for rooms up to 200 people. His power is very good, and the qualities praised by the manufacturers are real, especially the fact of hearing the same sound as the public. Strictly speaking, Bose ment just saying that there is no feedback. There's always when the microphone fell just in front. But it is much less.

A purchase so if you can afford and if we want to make a use as described in this notice.
