Problem: The sound quality changes…
• Repeat the steps in the previous troubleshooting section above before continuing to the
next steps.
• Disconnect the signal cable at the monitor’s input connector. 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, tweeter, or both) is at fault. It's also possible that the problem lies
elsewhere 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, please contact KRK technical
support.
Problem: The monitor hisses, hums, or makes other objectionable noises…
• Ensure that the power cord is connected snugly into the IEC socket on the rear of the
monitor.
• Check the connections between the signal source and the monitor. The Exposé XLR input
connector is a completely balanced system. If you're connecting an unbalanced output to
the monitor, be certain that you're using Pin 2 for signal and have Pin 1 and Pin 3 tied
together at the source end.
• Refer to the Voltage Select Switch for the AC Mains information of this manual to ensure
that the AC mains is properly matched to the operating voltage requirements.
• 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 use the same circuit.
