Noise Reduction: curiously, not very effective in reducing, but very effective to restore the profondeur.Muni an effective enhancer and exiter well: it can soften or restore fisheries in the mid / aigus.Doté system called Surround 3D sound is in theory, I say yes and no. Yes because it gives depth, but not because it is not enough (as appropriate). There is also a treatment it gives the bass or fishing, or simply increasing the bass, but fishing a lot, but not efficient enough for me.
Let's say the same brand I have the ultra-bass, more efficace.Ceci told me this device is essential for the midrange and treble: none replaces both.
No midi output or digital than analog.
It's simple: as buttons or menus to tourner.Pas of sub menus to get.
Some effects are excellent and indispensable, others were less convinced me (see characteristics).
In my possession for about 10 years: I am very happy in spite of everything to treat acute mediums areas and is the top.Et also give depth. Only the treatment of low, although correct, is not efficient enough for some specific cases.
