View Full Version : AV Receiver Question: Opitcal In
05-20-2011, 01:42 PM
I have a Sony HDTV, an HD cable box, a KLH 5100 AV Receiver and a 5.1 Bose Speaker system. I ordered an optical toslink cable that should be coming next week. I hooked up the sub to the speakers and the sub to the receiver. On the receiver it has an optical in and my HDTV has an optical out. How does the receiver know where the audio source is coming from? On the back they have square frames like DVD In/Out, TV In/Out, VCR In/Out, etc. For the Optical In, it's just a frame by itself along with a Coaxial in. How does it know?

Depends on your connections. If you hook the Optical out from your HDTV to the Optical in on your Reciever, then you will have the sound of your TV on your receiver.
You would just select that channel on your reciever to play from that optical source.
If you had a DVD player would hook that up digitally then listen to that sound source when selected if available.
BTW.. is this the back of your receiver?
If so, then you only have one optical in jack. You only have one optical in, therefore it automatically knows that it is active if you are using it all you have to do is make sure your receiver it set to the mode that plays on the optical in channel.
Of course you can't hook both your Optical and your Coaxial at the same time. You have to pick one or the other as your "digital in". I'm sure your receiver has a channel called "digital" or something like that. I'd check the manual if you have it to confirm this.

Yes that's exactly what it looks like in the back. Thanks DF. So if I have everything hooked up to the TV like my xbox and a dvd player, then the optical from my hdtv to the receiver will play through the speakers.

That should work as long as your TV can handle all the inputs and has the optical output.
Usually, the DVD player would get hooked up directly to the receiver, but since you only have one input, going to the TV first is your best option for this kind of setup.
