firmly into the correct jacks.
Make sure that a cable connects the output jacks on the audio source to the

Check all cables. Make sure they are connected to the “line-out” or “audio-out”
jacks on your audio source device.
Test the speakers using another audio source (e.g., VCR, DVD, portable CD
player, cassette player or FM radio).
Decrease the volume level on your PT6021’s wired controller or the volume level
on your audio source (if possible.)
Try a different sound source like a music CD.
Move your speakers to see if the interference goes away. If not, you may be
able to purchase a shielded stereo cable from your local electronics shop.
