not sure if this is the same thing but i had a prob with my mixer when i got my 1210's. since i got them the mixer sound levels aint quite right when compared to what they used to be for my old dex. At the moment my master is at about 10 and the gains r around 3. which is ok but the sound levels on the mixer aint quite on the 0db mark. i do however, need better speakers. at least then i can bang the gains up without the crap speakers i got now blowing up lol.
