    If I get the 722k, is there any lines that run to the 2nd TV? And if so, do they run from the dish or from the 722?:confused:

    The 722K has 2 sets of outputs - TV1 has all the bells and whistles - HDMI, component, TOSLINK, as well as composite, while TV2 has only composite A/V and RF outputs.

    So if you want to use the 722K in Dual mode, you will need either an RF cable between the 722K and the 2nd TV, or pull 3 cables for the other connection (composite video / analog audio).

    You need a black coax cable that runs from the 722 to the other tv...you can only watch in standard def on tv2.

    The most common method for connecting a Duo receiver in a pre-wired house is to use a pair of diplexers and send the TV2 signal back up the sat cable feeding the receiver. The second diplexer, located at the main junction, separates the TV2 signal back out again, and it is hooked to the line that feeds the TV2.

    If you are running new lines, you may do it the same way, or you may hook a cable directly to the TV2 output and run it straight to the TV2, say, when the TV2 room is right on the other side of the wall from the TV1 room.


    This pic is a little clearer, except that it shows the TV2 signal being split with a 1x3 splitter to feed 3 TVs instead of just one. Obviously all 3 of those TVs will have to watch the same show.

    A lot of my RG6 cable is white, and some is even blue. With two RG6 going to each location, I wanted an easy way to tell them apart.
