Jose...
A VERY IMPORTANT thing on the PA2XPRO.
Out of the box (in the store) the MASTER EQ is OFF!

So, You must go to Global mode, Master EQ and turn it on and adj it to your sound system/room.

Then, assuming a good sound system in sterio..it sounds AWESOME!

Mine sounds very PRO quality with the 2 Mackie HR824 monitors I use.
