Re: Question about headroom with dj mixers
Sorry, I meant to say try the pair of amps on one sub as an experiment.
You may already have power supply issues with the three circuits you have on the new rig. The old subs on one PLX amp, were more efficient, using less AC. One of the trade offs was a higher low freq. corner on the old subs. Going lower uses up a lot more power.
At this point, I'd double check all my cables for correct polarity, check the subs to make sure they're all hooked up with the same, find someone to tweak the settings on the rig with the Driverack(measured with Smaart say), get the gain structure sorted out, and experiment with the high pass on the subs.
With less efficient subs and not enough power for them, even going back to the four original MP418S subs on the 750 amps would be something I'd consider to get back some of the lost SPL in this club.
Best regards,
John
