Hi - I'm perceiving a lower output volume than I would expect from my system, and am wondering if it has to do with the way I've set it up or whether the SST module (type unknown) may have something to do with it. The amp is a CE 2000 in stereo mode, with one side feeding parallel JBL M-Pro MP215's, and the other side feeding a JBL MP418S subwoofer. The source is a Mackie 1604 board; the master output is usually around 0 dB or slightly less. In the signal chain are an Alesis 31 band graphic EQ (the EQ master is not set for any attenuation) and a very old Tapco EV-18 crossover. The crossover frequency is approx. 125 Hz. The amp sensitivity is set to 1.4V. The system sounds fine, but my experience with other amps of similar power is that I needed to keep the output level controls fairly low to keep from blowing the band out of the basement. With this system, I can turn the level controls on the CE 2000 to about the "2" position before any significant feedback starts to occur, and even at that level the volume is not unreasonable for the basement. Is there something about my setup that might cause this? Also, I don't know if an SST module is installed, and if so what type it is. I bought the amp new with no other sST hardware. Could it be that the combination of my setup and an installed SST network could produce lower output? Thank you!
