There are several ways to get sound to an Amplifier:

• if the Amplifer is HDMI compatible: connect as follows:
  • Connect the TV Box to the HDMI input of the amplifier
  • Connect the Amplifier HDMI Output to the TV
• if the Amplifier is not HDMI compatible you can use the Electric S/PDIF output from the TV Box but the Amplifier needs to be Dolby compatible
• if the Amplifier is neither HDMI not Dolby compatible, you may use Audio output from your TV Set (optical S/PDIF, RCA...)
