6 Troubleshooting and Warranty
6.2 Warranty
StudioLive ™ AI-Series Loudspeaker
Owner’s Manual
Loudspeaker has hum or buzz.
Nearly all hum and buzz problems are related to cable grounding. With
the loudspeaker at low volume, remove input and output cables, one at
a time, until the noise disappears. Try replacing the suspect cable.
If you are using two-conductor cables with unbalanced ¼” connectors,
try replacing with balanced cables using TRS or XLR connectors.
Try plugging loudspeakers and the external mixer into outlets that share a common
ground. If necessary, use an extension cord to plug the external mixer into the same
outlet as the loudspeaker—but do not run the AC cord bundled with signal cables.
