COMMON CONNECTION FOR
THE ACT-1515X
BASIC TROUBLESHOOTING
1) POWER ON/OFF SWITCH DOES NOT
LIGHT - Check your source of AC Mains power by plugging
in something you know is working into that same outlet.
Check the firmness of the connection of the AC Power cord
in both the wall and the IEC panel mount socket. Unplug the
AC cord and check the fuse for continuity with a multimeter
or ohmeter. If fuse is blown, replace it with the same type
and size, and then plug AC cord back into the wall outlet. If
fuse blows again, or Power on rocker switch fails to light,
service is required.
2) NO SOUND - Is power present? Is the Signal LED
lighting up? Are the cables firmly attached and plugged into
the correct jacks at each end? Are the level controls up high
enough? If the signal source (green LED) does not light try
first changing signal cables and check the mixer for signs of
signal at the output. If all the above is not in question, the
unit requires service.
3) BAD OR PARTIALLY MISSING SOUND - If
the bass is weak, it is likely one or both woofers are blown.
If the highs are very muted, it is likely the compression
driver is blown. If the midrange is muted, it is likely the top
woofer is blown. If the distortion does not seem to get worse
with increasing level, the amplifier alone may need service.
4) INTERMITTANT SOUND - It is possible that you
have a bad cable or connector socket. It is also possible that
this is a damaged speaker or amplifier.
5) LOUD ANNOYING HUM - You may have a
ground loop. Double check all connections and cables. A
miswired cable can significantly increase hum. If all else
fails and you can insure the amplifier chasis and metal
speaker parts will not be touched or closely approached
during use, try lifting the Earth ground with the rocker
switch (#8).
To reduce the risk of fire or electrical shock, do not expose this unit to rain or excess moisture. Do not operate your ACT-1515X(F) in or
near a pool or other standing water. In the event the powered speaker comes in contact with the water, an electrocution hazard may occur.
Do not bypass or defeat the grounding or polarization means used on the ACT-1515X(F) amplifier. Make sure all blades on the polarized
grounded power plug are fully inserted into the AC mains power receptacle. Ensure the power cord is not stretched, pinched, chafed, or
otherwise damaged. Ensure the power cord is routed safely and secured to avoid the possibility of someone tripping over it.
