XLR line input with volume, an XLR microphone input with volume, EQ usually severe acute medium plus or minus 6 db, a line out XLR, speaker output of additional Speakon, a base area, an inter sector. It is fairly complete. There are feet, corners, etc. grid is needed. The sound is rather soft, not aggressive. The max level is not huge but enough to return. It is short in serious but for me it is rather a quality back. I use it for some time back. We read in another review that it blows, well mine does not blow, just a bit on the mic but it does not get in use.
In short it is quite usable, and when you see the price it is blown!
