What to do
• When connecting a microphone to the F1 Model 812 Loudspeaker, make sure the INPUT 1,
SIGNAL INPUT switch is set to MIC.
• Check to make sure that all system connections are secure. Lines that are not completely
connected could create noise.
• If using a mixing console, external source or receiving input from the F1 Subwoofer, make sure
the INPUT 1 SIGNAL INPUT switch on the F1 Model 812 Loudspeaker is set to LINE.
• For best results, use balanced (XLR) connections on the system inputs.
• Keep all signal-carrying cables away from AC power cords.
• Light dimmers can cause hum in loudspeaker systems. To avoid this, plug the system into a
circuit that is not controlling lights or dimmer packs.
• Plug the audio system components into power outlets that share a common ground.
• Check cables at mixing console inputs by muting channels. If the hum goes away, replace the
cable at that mixing console channel.
