Just plug it in, follow the onscreen instrctions and it will, by the magic and genius of sony, make the sound from your TV come to life. It has made blueRay films 10 times the exeriance, and PS3 games seem more real than ever before, all from one little black box.
Hook it up to some nice speakers (i reccomend B&W or Scandyna) and you will not regret the expense.
All in all sony's best bang for the Bucks AV reciever.
