Ok so I broke down and bought a power amp and yes it was not a QSC. I had my eye on a new QSC RMK1450 but the owner of the store would not budge on the $450.00US price tag. SO anyway I was at another store looking at their power amps and naturally the store owner says yeah we just had two QSC amps but one just sold the other day and the other one was put on lay-a-way. This is a mom and pop store by the way. Anyhow the 3 sales people begin giving me the run-down on all amps they had (stewarts, crown etc). All of which were out of my 400.00 price range. I tell them that I wanted to pick up a qsc 1450 which has 1400w on a 4ohm load bridged mono. This amp would power my SWR Goliath Senior 6x10cab (1000w rated). They then began the pitch on a Crest Cpx1500 which is 1500w @4ohm bridge mono. So after some haggling and their bashing of QSC and they all instantly became bass players who would swear by this crest amp, I bought the amp. Now my current set-up uses an Ampeg B2R head that I am using as a Preamp into the Crest CPX 1500 via an XLR Cable and then a speakon cable from the power amp to the cab. 1. On my preamp (b2r) how do I set the gain when running into a power amp. When i was just running the b2r i would max the volume then adjust the gain to just before the clip induicators would come on. How would i set the gain on the power amp (crest cpx1500). 2. I was a little dissapointed with my perceived loudness of the cab with the new amp running bridged mono. I definitely noticed a differnce in the lows (shaking the floor) but to me the midrange and overall loudness did not seem to improve. Could this just be me? 3. Finally, the one thing that surprised me was how hot this amp got. The top of the amp was not to the touch. Not hot enough to burn your hand but the b2r i had never even got warm. Is this typical? Should I be concerned abouth this. The amp has a 5 year warranty. I know I probably should of got the QSC but my income tax money was burning a hole in my pocket! Any help on the set-up of this combo would be appreciated!
