This product is primarily a graphic equalizer 31 band analog twice (what fun) both channels. It also possde limiter per channel which can rgler rduction the magnitude of the gain "threshold" (no other rglages for the limiter, 4 LEDs indicate the work of the limiter).
Each channel knob to a possde rgler the level of a vumtre consists of 8 LEDs, a switch to see the level of input / output on vumtre, a switch to "activate" or not the equalizer on the channel. For each channel can also defines a attenuation / increase of + / - 6 dB per band or + / - 12dB per band.
Gnrateur a pink noise will make the legalization of rglages using a spectrum analyzer. The equalizer also has a subwoofer output and a knob rglant the level of this output.
And finally a strong function INTERESTED (a major reason for my purchase), the feedback-detection for cahque channel. In conventional operating mode of each fader strip possde a red LED that lets you know we put o fingers in the dark. Mode-detection feedback LEDs s'teignent and intensity varies with the volume of each band. So for the DTECT frquence that causes arsen just push a little microphone and the gain of the master. At the onset of feedback from the LED fader frquence causing the feedback, begins to shine more than others (that trs net). Just then the attnuer frequencies. Of course we can not always eliminate completely the feedback but it can considerably delay its coming.
In dpart I did not really believe the APRS and then I confess that I have test t bluff by the effectiveness of the System.

Level connections are the entries in 6.35mm jack or XLR output also including the subwoofer.
The unit is rack-mount, in fact it is possible to dvisser the two steel plates cahque ct DSIR if you do not use rack and save space.

UTILIZATION

The device is very simple to use, in 10 minutes we realized the principle of each function. The long stroke faders allows greater precision (at dtriment congestion, 2U).
Unfortunately it is a mania in Behringer, the knobs and faders are not really sturdy, it's not the top in terms of comfort, I do not like for example the knob of SETTING THE level of input e that possde notches, so a lower precision (they are small especially the knobs).

The book is about him trsrduit (a few pages) but adequate and clear. A table of correspondence between rcapitulatif instruments / voice and frquences is useful.

SOUND QUALITY

I use this unit to the sound, I find myself often in rooms with poor acoustics and quality j'espre dsormais opportunity to correct it (well as best possible).
In terms of sound quality I have nothing to say except a lightweight snap (sometimes) when using the switch activation / disabling of the legalization (ca priori is not a PBS is used as that in the rglages). When the device saturates must rush to lower the level of clicks to avoid strong, fortunately the limiter should avoid this kind of dsagrements, it works quite effectively and fawn with a rglage one (very quick set up).
I can not really comment on the sound quality of the device as a given that my Systm sound quality is pretty bad and I could not compare with other products equivalents ).

OVERALL OPINION

Well, except for knobs that are a little LGERS the rest is really nice. I love the design and reporting quality behringer price is really excellent. Feedback from the dtecteur m'vitera dsormais lot of trouble. This is not a high-end course, but for a price like this is really trs INTERESTED, especially from small functions that are associated very useful.
In short a good product for those who do not wish to make a fortune in this type of equipment but all the same who seek something serious.
