A:AnswerYes that pretty much sums it up. I did run my optical connection from my satellite box. You could also use HDMI cables in and out of the soundbar.
A:AnswerThe 2.1 means 2 speakers and a subwoofer. The soundbar contains the 2 speakers (right and left channels) and the subwoofer is just the subwoofer.
A:AnswerThere's not much to install on a soundbar. Plug in the power, plug in your input (either optical or HDMI), and that's all. Connect it to your wireless subwoofer using the instruction manual.
A:AnswerThis soundbar has multiple input options: Bluetooth, HDMI, SPDIF Digital Optical, USB, and a 3.5mm audio jack. So depending on what model echo you have, you should be able to use Bluetooth, and maybe the headphone jack if you have the 3rd gen.
A:AnswerYou have to enter your TV setup to set the blue tooth to your sound box. You could also call the manufaturer and they will walk you through the setup. Setup varies with each TV.
