Hello I'm buying lately and its little wonder j'avous trs be satisfied with this product. Double amplification and limited compressor, noise gate, two input microphone and a sound that thunders. Usually I used two basic box + 2 JBL 900 MR2 and my surprise the two B412DSP Sufis are the work of the rich base and treble trs transparent and versatile. I have 4 dja B300 but it has nothing to do with the new Bravo model Behringer and for the price I love this product and I recommend everyone and anyone who is looking not only extremely good sound which may limit the budjet.
