Troubleshooting
Many problems can be eliminated by re-checking the wiring and
settings of the unit. If a problem cannot be solved using the guide
below, please call the AudioControl team for further assistance, or
e-mail us at sound.great@audiocontrol.com
1. No Sound
a. Verify the Power LED is a splendid green.
b. Verify the Protection LED is Off.
c. Verify the source unit is operating.
d. Check the speaker connections.
e. Check the power fuses on the Epicenter amplifier.
f. Check the ACR-3 (in red-LED mode) is not at minimum.
2. Protection LED is flashing:
a. Check the red protection LED flashing sequence, and compare
the problem codes with this table. This will help you identify
the problem, like having your very own tiny blinking service
technician. (The blue mentioned in the table is the blue glow
from within, near the heatsink area, and not the Power LED.)
b. If the problem code indicates a short circuit, check the speaker
wiring, and check that the speakers are not shorted internally.
c. For under-voltage and over-voltage faults, check all the power
connections to the Epicenter, and check the vehicle power
generation system, loose fanbelt, duff alternator, and so on.

d. For over-heating problems, make sure the Epicenter amplifier
is receiving adequate ventilation.
e. Disconnect all speaker wires. If the protection LED is still flash-
ing, and the unit has cooled, something rather serious has
happened inside the unit. Call AudioControl’s lonely folks in
customer service.
