Connect the detachable power cord (included in the packaging with the subwoofer) to the power receptacle, and plug the other end of the power cord into an AC outlet. 3.Fan Vents Do not obstruct the ventilation openings of the subwoofer. Fans move air over the heatsinks to cool down the power transistors. If these vents are restricted, then the subwoofer may overheat and shut down. Make sure that the AC power is matched to the AC power indicated on the rear panel (to the left of the IEC receptacle). Disconnecting the plug's ground pin is dangerous. Don't do it! 4.XLR Inputs Balanced XLR female connectors are provided for the left and right inputs.

As such, the loudspeakers should also be turned off first, followed by the subwoofers, then the mixer. This will reduce the possibility of any turn-on or turn-off thumps and other noises generated by any upstream equipment from coming out of the speakers. Owner's Manual 9
