  2. Locate Audio: Range in the menu.
You would like the best audio qualityChoose the Narrow option.
You have a stereo audio system connectedChoose Normal or Wide.

Poor Audio Quality

Try the following fixes for issues with poor audio quality:

  • Check the Music Choice or DMX digital light indicator:
    • If it blinks, check all connections from the wall to the MC or DMX converter.
    • If the light is solid, check all audio connections from the MC or DMX converter, through the stereo and out to the speakers.
  • Check to see if there are worn selector switches, volume knobs, or tone controls as these can cause poor audio quality.

If the audio problem persists after taking these steps, contact your Cox cable customer service representative for assistance.
