Hi,
what exactly do you want?, if you want full DD or DTS from your blu ray movies you will need an optical cable or digital coaxial cable from your player to your amp.
if you want to improve audio from your tv then an optical lead from your tv to your amp will achieve this.
dont forget if you use this to turn the volume of your tv to zero otherwise it will echo.
forgot to add you will need to go into your blu ray player sound settings and set it up in there.
