In order to improve the sound quality, make sure that you observe the following guidelines:

• Check the quality of the incoming signal on the TV with a different source like DVD or VCR.
• Splitting the signal will make it considerably weaker. If you use an antenna cable splitter: connect the antenna directly to the TV without the splitter.
• Check your cables and cable-connections.
   
  • Make all your cables as short as possible.
  • Use high quality antenna cable.
  • Connect the plugs well into their sockets.
