The sound quality changes...
• Repeat the steps in the 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, tweeter or both) is at fault. It’s also possible that the problem lies somewhere in the electronics.
• Play some
• 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 solution to correct your monitors. The service department can be reached at
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 RoKit G2’s XLR and TRS connectors are a completely balanced system. If you’re connecting an unbal anced 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.
•Refer to the Connecting Your System section on page 6 of this manual to ensure that the AC mains is 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 such as dimmers, neon signs, TV screens, and computer monitors. These devices should not be using the same circuit.
