[QUOTE="Geoff Doane, post: 145638, member: 1155"] Re: Comparing amplifier specs - gain 860W into 4 ohms is 58.65V 58.65V / 1.1V is 53.32 or a voltage gain of 34.5 dB So your DSP gain and limiters (if you're using them) have to be set 2.5 dB lower than they are now. GTD Oops, sorry, I looked the QSC sensitivity, not the B. Running it again, I get 58.65/.775 for a gain of 75.67, which my ancient TI calculator tells me is +37.58 dB. So gain needs to be roughly 5.5 dB lower. [/QUOTE]
