ACT-1515X

1000-WATT ACTIVE FULL-RANGE SYSTEM

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.
