ARNINNG!: When the AC Power is on, there is a potential of having dangerous voltage at the output terminals on the rear of
the amplifier. Use caution not to touch these contacts. Turn off the AC Mains disconnect switch prior to making any connections.
IMPORTANT!: QSC recommends that you connect jumpers where the terminals are the same points electrically. Refer to
thru Figure
1. Turn the AC Mains power switch to on. The amplifier starts in the Run mode, or the last mode it was in before power was turned off.
