Our TV is connected to a lot of audio system at home. I actually do not dare switch the TV on without asking my husband or daughter's assistance because of the complex connections my husband did.
My husband loves to tinker with electronics and gadgets so it comes as no surprise that we will create a very intricate connection of home theater system speakers in our living room.
I really appreciate the great surround audio when we watch on the big screen but how the whole system works is a great puzzle to me. Maybe I'm just not the kind of person who understands all these audio/video complexities.
