Digital Audio In Explained
Digital Audio In
OK. Let’s say the sound you want to hear over your speakers isn’t actually coming from your console or Blu-ray player.
Let’s further say it’s coming from the TV itself – say, you’ve used your TV’s smart feature to dial up Netflix or a sports event. That means that, essentially, it’s your TV that will need to send sound to the receiver. But how does it do this?
The answer is in something called ARC (Audio Return Channel). It’s a feature of most modern HDMI systems that allows the TV to send audio back to the receiver. Sometimes, however, a TV won’t be compatible with ARC. You’ll need to check the details of whichever model you are using, but if this is the case, it means you need to break out the big guns. And by big guns, we mean optical cable, which is a special type of thin cable with a tiny transparent dome on each end, that in this case is used to send audio back and forth. That’s what you’ll be plugging into the TV audio port.
No optical? No problem. Use a coaxial cable, or coax, connecting it from the coax out on your player. Coax cables have a single pin surrounded by a metal ring, and carry digital sound.
You can also use the Digital Audio In section to connect a set-top or satellite box, an old TV without an HDMI connector, or a DVD or Blu-ray player. Chances are, you probably won’t have to worry about this particular section of the receiver. At least, don’t start messing with it until you’re absolutely sure that your HDMI cable/ARC isn’t happening.
