Query: Digital Audio Converter

We just upgraded to the Direct TV Genie; but was amazed to learn that it did not have a Optical Audio output on a single Coaxial output. Our audio system uses an Optical Audio selector to drive our surround sound as well as outdoor speakers.The C2G converter was the perfect answer to our problem. It is one of the few on the market; but maintains a competitive price. It works great, however it does require its own power supply, I simply used the switched power output on the back of my surround sound amp; when its on the C2G is on.
