Connect all sound sources to the appropriate inputs i.e., microphones,
keyboards, CD players, karaoke machines. The supplied microphone is ideal
for vocal.
When ready to operate, plug the AC cord into the power source.
Make sure that the unit is turned off before connecting to the AC power
source to avoid possible loud transients which can damage your speakers
or your ears. Before turning on, connect up the speakers and all inputs and
outputs desired and turn down the Master Volume.
