The sound quality changes...
 Repeat steps in the previous troubleshooting section above before continuing to the next steps.
 It is possible that the change in sound quality is due to changes in the room or listening position. Low frequencies (bass response) can be increased or reduced by
changes such as furniture and/or large equipment placement. Try moving the speakers or listening area a different position or return the room back to where the
sound quality was acceptable.
 A reduction in bass frequencies may be a result of polarity inversion between the left and right channels or long delays between the left and right channels.
Information in the mix may also be panned differently which will result in differing cancellation. Check the audio source and verify if one channel is polarity flipped
or long delays are being used. Avoid polarity inversion by using matching cables and use one type of input connection only. Do not use an XLR/TRS balanced input on
one monitor and an RCA unbalanced input on the second monitor.
 Disconnect the signal cable at the input of the monitor and adjust the volume control to the minimum setting. With power on, place your ear close to each driver
(tweeter/woofer) and listen for noise (i.e., a slight hiss or hum) while slowing increasing the volume from the minimum setting. It is important that the volume is
slowly adjusted from minimum setting to avoid any spike in sound levels while the ear is close to the driver (tweeter & woofer). If there's absolutely no sound
whatever, it could be that the driver is at fault. It's also possible that the problem lies somewhere in the electronics.
 Play some non-distorted source material at a low volume. Carefully cover the woofer (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.
 Verify the source signal level has not changed or source has changed. This can be tested by connecting the source headphone outputs to a set of headphones and
verifying the sound is not loud or distorted. If the sound is poor at the source (preamp stage) than it is not the active speakers.
Once you have a better idea of what may be at fault then contact our service department. They will help you determine the best solution to correct your issue.
The subwoofer hisses, hums or makes other loud noises...
 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. Make sure all connections are secure and that the cable is not damaged or wired incorrectly.
 If you are using an unbalanced output to balanced cable conversion, make sure it is correct. The shield is connected to the unbalanced ground of the source and pins
1 and 3 of the XLR (or the sleeve and ring on the ¼” TRS jack).
 All audio equipment should use the same ground point. Check all other devices using the same AC output in the building like light dimmers, neon signs, TV screens,
and computer monitors. These devices should not be using the same circuit.
 Verify that the signal cables are not routed near AC power lines or other EMI sources (including wall power adapters and computers).
 Excessive hiss may be a result of an incorrect gain setting before the speaker connection. Verify the source signal is not noisy before connecting the monitors. This can
be tested by connecting the signal source headphone outputs to a set of headphones.
