I've used 882s since they came out . Before that , I had used the Rane SM26 ? ( which the Behringer used as "inspiration" for their product ) .
IME, THE 882 is an eminently useful product .

Plugging into ( say channel #5 ) input , breaks the normal ( from the Main L,R input ) , & puts that signal through a portion of one dedicated 4880? chip ( which has a volume control on it ) and sends it back out to the #5 output ( after being buffered ) .

So, one can use the 882 as a 6-in / 6-out line-driver with individual level matching capacity ( as stated in the manual ).

Mind you, when setup like this one still does not get a single stereo ( ganged master ) knob that effects all these 6 output levels at the same time ( which I think is what Pano was pointing out before I opened up my yap ) .
