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 [email protected]

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.
