The monitor 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's headphone
output to a set of headphones.
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.
