Noise/Hum
• Check the signal cable between the
mixer and the loudspeaker. Make sure all
connections are secure. These problems
usually produce crackling noises or hum.
• If you are using two or more TH-15A
active loudspeakers, try plugging them all
into the same AC outlet panel or outlet
strip. The purpose for this is to connect
them all to the same earth ground point
and reduce the possibility of creating a
ground loop.
• If connecting an unbalanced output
to the TH-15A balanced input, make
sure the shield is connected to the
unbalanced ground and to pin 1 of the
XLR.
