I use the wireless system for a year now and I must say that I am filled
I love that it is the autonomy of 17 hours with a standard 9-volt battery (alkaline anyway) but also the scope ... More or less one hundred meters under the conditions ... In addition, as is a system diversity (two antennas) he never answers (once a year ...) and the sound and perfectly rendered especially if you have a good jack RAPCO kind between the receiver and the amp. You can also thanks to the XLR plug the receiver into a mixing live but only if it does not use any other amp ...
Before this one I tried the model of Gibson at Samson j'aiami well as what was the size of the emitters. But I was disappointed because in the shop and I tried it stalled several times when I was two meters from the amp ... and the battery was new ... So even if the system is slightly larger Shure I preferred ...
Nine it is € 370 but I think that if you want to have his gear there must be a minimum ...
Finally with the experience I would do three times rather than the choice ...
