TROUBLESHOOTING
LED DOES NOT LIGHT UP
Verify that the unit is plugged into the power outlet. If
plugged, check if the power outlet is active and
supplying the appropriate AC voltage.
Inspect the power cable. Never use one that has been
altered in any way.
Make sure the subwoofer's MAIN POWER switch is ON.
Inspect the fuse (pg. 5).
LED LIGHTS UP BUT STAYS RED
Make sure that the POWER switch is either set to ON or
AUTO position.
Check if signal is present at the RCA. The LED should
turn blue when signal is detected and produce output.
If the LED remains red, then the problem is at the source
of the audio cable:
Troubleshoot the RCA cables by temporarily
connecting them to the stereo left and/or right of the
source unit. The subwoofer can be heard if the cables
are good.
If the cables are confirmed to be okay but there is still
no output when connected to the SUB OUT of the
receiver/processor, check the subwoofer setting at
the source. Once again, make sure that the
subwoofer's POWER switch is either set to ON or
AUTO.
HUM NOISE
Keeping the subwoofer on, unplug the RCA cable or speaker
wires from the subwoofer. If the noise goes away, then the
problem is coming from the source. There are 2 options to
solve this problem:
Make sure that all other units in the system are grounded
together (~18 - 22 AWG wire), with the exception of our
subwoofer.
Grounding the loop isolator (on the RCA side) and the
cheater plug (on the AC supply side) may be a
temporary/quick solution. However, we highly
recommend using the first option above.
If the noise is still present even though the RCA cables are
unplugged, then try changing the AC outlet.
If the hum noise still persists at this point, please contact an
Earthquake Technician by phone (US Toll Free 1-800-576-
7944) or e-mail [email protected].
