Question about Behringer Pmp3000 16 Channel Audio Mixer
I am running unbalanced
You don't say which QSC Amp. Assuming it is one that can only drive down to 4 ohms you are going to have to run a pair of the jbls in series for each channel of one amp (making the impedance 8 ohms for the pair) and run the other pair from the channels of the other amp. Running unbalanced is not a problem except for interference but you don't say what the source is. If you have more than one output (aux or sub bus for example or poss even a monitor output if you're not using it) it may be beneficial to take one amp from there as you will have some control over the relative levels from the mixer. Otherwise you'll just have to parallel the amps.

Those specs would be right - I have this same board but the amp was fried by a previous owner. I pulled the amp board out and tossed it and use the mixer now to drive an external amp. Great board. This amp is rated at 1200W "peak", bridged into an 8ohm load. That would equate to about 900W RMS bridged into 8ohm or 450 per side into 4ohm loads per side. You can't daisy chain all 4 speakers....impedance would be too low. You can run two of your 8ohm speakers per side - that results in a 4ohm load per side for the amp. That would give you amp delivery of 450W per side. Your speakers are rated to handle more than that so you're fine. For the record.....you could run one speaker per side no problem....just lower power output.
