Category : Technical Assistance: MXSP-SB252 Soundbar TV Speakers

Why does the MXSP-SB252 Soundbar lose its sound?

Please turn the volume up of the source device, for example TV, set top box, etc. and re-adjust the sound of the unit to trigger the auto-on function.


Why is there no sound coming from the MXSP-SB252 Soundbar?

Please turn off all the sources and disconnet all cables.
Once you have disconnected all the cables, switch the Soundbar on again.
Once the  MXSP-SB252 Soundbar is working, please re-connect all the cables - you should hear the sound coming through. 


I connected an HDMI cable from the ARC socket of the MXSP-SB252 Soundbar to the ARC socket on the TV. However the sound has stopped although everything is showing?

This may occur if the connections have not been applied properly. Please make sure that the you have followed the steps below:

  • Step One: Please confirm the connection - TV(HDMI-ARC connection) to MXSP-SB252 Soundbar(HDMI-ARC connection).



When I connect the MXSP-SB252 Soundbar to the set top box directly via an optical digital cable, why do I have to turn off Dolby Digital?

Unfortunately the MXSP-252 Soundbar does not support the Dolby and DTS decoder, so please change the Digital Audio Output format to PCM for TV, player and set top box.
