I have an Ampeg B2R and a Crown XLS 402. Ive got it hooked up and it works, but its not done right. As of now I have a mic cable running from the balanced output of the B2R into the input of channel 1 on the power amp. From th eoutput of channel 1 on the power amp I rigged up an old cable to the two posts into my cab. Now, I really want to connect it correctly and use both channels. The problem: My B2R has a 'power amp in' and preamp out' jack, but I cant connect it to that becuase of the mic cable required for the power amp input. Then there is the two inputs for the power amp, do I just use some king of Y cable? Should I connect it through the "power amp in" "preamp out" or like I have it? I know my description is horrible, so if needed I will take a picture later tonight.
