Recent devices offer interesting video or audio connectors, but never in sufficient numbers. This article helped me connect the audio from my Apple TV and TV demodulator single optical input on the home theater. However a small sheet with a small scheme could have avoided me struggle to understand why I had no sound on the home cinema. In my case, with 2 outputs for an input, think off was a source for the second sound source arrives at the home cinema. If the two audio sources are illuminated the home cinema does not know what source it must process. Otherwise I am happy with the product, its price and delivery time.
