    This is something i have not noticed before with my B-Max into my 1602. When i have the amp set in paralell mode, one GS112 plugged into each speaker output, i notice that when i have just one channel gain turned up the speaker sounds normal, but when i turn up the second channel gain to match the first, i have net loss of volume and especially bass response in both. :confused: :confused:

    Turn either channel down and the remaining channel returns to normal. I also tried this in stereo mode using a splitter out of the BMax. Same result. Is my PLX going bad or is this normal??
  2. It might not be a problem with the amp. Sounds like there might be phase cancelation between the two cabs. Did you check to see if the cabs are wired out of phase to each other?
