  • If the main unit is powered off, the wireless subwoofer will go into standby mode and the STANDBY LED on the rear of the subwoofer will turn red after blinking in blue several times.
  • If you use a device that uses the same frequency (5.8 GHz) as the Soundbar near the Soundbar, the interference may cause some sound interruption.
  • The volume of the Soundbar is too low or muted. Adjust the volume.
  • When any external device (STB, Bluetooth device, mobile device, etc.) is connected, adjust the volume of the external device.
  • For the sound output of the TV, select Soundbar (Samsung TV: Home → Settings → Sound → Sound Output → Select Soundbar).
  • The cable connection to the Soundbar must not be loose. Remove the cable and securely connect it again.
  • Remove the power cord completely, reconnect it, and turn the power on.
  • Initialize the product and try again.  
  • Check whether the LED indicator on the rear of the Subwoofer is on in blue. Reconnect the Soundbar and Subwoofer if the indicator is blinking in blue or solid red.
  • You may experience an issue if there is an obstacle between the Soundbar and Subwoofer. Move the devices to an area away from any nearby obstacles.
  • Other devices sending radio frequency signals in proximity may interrupt the connection. Keep your speaker away from such devices.
  • Remove and reconnect the power plug.
  • If no sound is detected, please check the connection between the speaker wires and metal clamps. The exposed metal wire parts need to make contact with the metal part of the clamps.
  • Having the wires inserted too deep, causing the clamp to make contact only with plastic casing of the wires will cause no sound.
  • The original volume of the content you are playing may be low. Try adjusting the Subwoofer level.
  • Bring the Subwoofer speaker within 3 metres of the Soundbar. Some Subwoofer speakers may not have a strong enough signal to work far from the Soundbar.
  • Install the latest firmware update.
  • If there are any objects between the Soundbar and Subwoofer speaker, it could cause a problem. Please reposition these to a place without such an object.
  • There may be sound jitter or delays when the Subwoofer and Surround Speaker are far away from the Soundbar. Please place them near the Soundbar.
  • There may be sound jitters or delays when the Soundbar is near an instrument or electrical device that can cause radio interference. Place the Soundbar far away from such devices that can cause radio interference (e.g. wireless router).
  • Change the TV network connection status from wireless to wired.
