I am wondering if you could e-mail me the schematic for the v3000plus, as well. I am having troubles and would like to try chasing down the problem.
The input signal from the mixer is maxed, and even with the gain attenuators cranked all the way up, the amp does not achieve max output as indicated by the FP LEDs.(impossible to drive to clipping!) Tried all settings - Both channels, Sub xover, HP filter DIP switches, and mono/stereo - same symptom with all settings.
Yes the problem is the amp - ran the same signal to a different amp and performs as expected.
Any ideas of what to check first?
