For some reason the soft on protection circuit has failed. it is not a simple fix and would require the amplifier module to be removed from the speaker to assess the damage.

If you use 1/4 inch cables they MUST be TRS cables (balanced lines). Guitar cables that do not have the third contact (ring) will have buzz and hum. Use either XLR or TRS cables. Also power the speakers and mixers from the SAME receptacle as the speakers.
The JBL EON 305's are 8 ohm speakers. The PMP5000 wi;; produce 400 Watts per side into a 4 ohm load (600 Watts peak). Into your 8 ohm speakers, the peak current will be halved while the voltage remains the same so you ACTUAL power per side is 200 Watts. It is hard to know how much you expect to get out of the amp. This power would fill a venue of at least 2000 sq ft. If you need more sound, try borrowing another 8 ohm speaker for each side and parallel them with the EON's as a test. That will double the power and add 3 Db more of sound. Your main slider should be around unity typically. This amp is a class D switching type (very efficient) and runs on +/- 70 volt rails. giving about 45 volts RMS output. At 4 ohms, this is just over 10 amps giving 450 Watts... at 8 ohms this is around 5 amps or 225 Watts.
Please read my tip on Fixya about the ground hazard of channel A when using 1/4 inch cables out of the PMP units... essentially the BARREL of the connector from channel "A" is the HOT,... NOT the tip of the PLUG. Ground the barrel IN ANY WAY AND YOU FRY CHANNEL "A" AMP !!!
