Check that all the PA devices such as an amplifier
and mixer are off.

Connect the supplied AC power cord to the CU.
NOTICE • Be sure to use the supplied AC power cord. Using an AC
power cord other than the supplied one may cause
problems such as damage to the CU, which can be very
dangerous.
• Be sure to connect the AC power cord into a properly
grounded wall outlet. Improper grounding can cause
electrical shock.
