Press the Power button on the wired controller.
Disconnect and then reconnect the power adapter to both the wall outlet and
the subwoofer.
If the power adapter is plugged into a surge protector, make sure the surge
protector is switched on.
Connect the wired controller to the subwoofer.
Plug another device into the same jack on the wall outlet to ensure the outlet is working.
Verify that the grey-colored DIN connector is firmly inserted into the DIN
connector jack on the subwoofer.
Ensure the pins are aligned between the plug and jack.
Remember, the arrow should be facing up.
Verify that the subwoofer’s AC power cord is plugged into both the wall
outlet and subwoofer.
Verify that the Power button has been pressed and that an EQ LED is illuminated.
Turn the rotary knob to the right to raise the system master volume.
Check volume level on the video gaming system or alternate audio source
device, and set at mid-level.
Connect audio cable from the audio source. Check plug connections on both
the subwoofer and audio source. Make sure these signal cables are inserted
firmly into the correct jacks.
Make sure that a cable connects the output jacks on the audio source to the
input jacks on the XA3021’s subwoofer.
Test the speakers with another audio source.
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 XA3021’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.
Adjust the bass level on the wired digital controller or subwoofer.
Try a game, movie or song—anything with more prominent bass tones.
Some low hum may be detected when your speaker system is powered on without
an audio source playing, or when the volume is set at an extremely low level.
If you are using a surge protector with your XA3021 speaker system,
disconnect and plug the power adapter directly into an AC wall outlet.
Move your cables. Check to ensure they are making a clear connection.
Disconnect your stereo cable from the audio source. If the loud hum goes
away, lower the volume on the audio source.
Adjust the bass level on the wired digital controller or subwoofer.
Verify that all cables are connected properly and are making a clear connection.
Decrease the bass level on the wired digital controller or subwoofer.
Because the subwoofer IS NOT magnetically shielded, it may cause distortion if it
is placed too close to your monitor/TV. Move the subwoofer so it’s at least 2 feet
from your monitor/TV.
