P
roblem: The sound quality changes...
• Repeat steps in the previous troubleshooting section above before continuing to
the next steps.
• Disconnect the signal cable at the input of the monitor. With power on, place your
ear close to each driver (tweeter/woofer) and listen for noise (i.e., a slight hiss or
hum). If there's absolutely no sound whatsoever, it could be that one or more of
the drivers (woofer or tweeter or both) is at fault. It's also possible that the problem lies
some where in the electronics.
• Play some non-distorted source material at a low volume. Carefully cover the
tweeter (to block the sound) without touching the diaphragm. Is the woofer producing a
clean sound? If there is not a clear tonal quality or any sound at all
then the woofer probably needs to be replaced.
• Cover the woofer so you can hear mostly the tweeter. Is the tweeter producing a
clear sound? If there is not a clear tonal quality or any sound at all then the
tweeter probably needs to be replaced.
• Once you have a better idea of what may be at fault then call us and speak with
someone in the service department. They will help you determine the best solu
tion to correct your monitors. The service department can be reached at 954 316-1580.
Problem: The monitor hisses, hums or makes other loud noises...
Here are some suggestions that will help you eliminate these undesirables from your
system:
• Make sure that the power cord is plugged snugly into the IEC socket on the rear
of the monitor.
• Check the connections between the signal source and the monitor. The
Neutrik® Combo connector is a completely balanced system. If you're connecting
an unbalanced output to the monitor, be sure that you're using PIN 2 for signal
and have PIN 1 and PIN 3 tied together at the source end. This can be done by using the
appropriate cable or adapter.
• All audio equipment should use the same ground point. Check all other devices
using the same AC output in the building like dimmers, neon signs, TV screens,
and computer monitors. These devices should not be using the same circuit.
