The XL2 version is an update to the XL1 that will be shown later on the floor -- it's the big sister to the XL1 media center system with a built-in HDtuner.
Its multiroom audio capabilities are similarly extensive with Powered Zone 2 and 3 capabilities, multiple DC triggers, bidirectional RS-232, and Onkyo's exclusive Universal Port for connection of an optional iPod Dock and HD Radio tuner.
DirecTV paired its HD interface with the five tuner, RVU ready HR34 Home Media Center DVR back in March, so what will it do next to take advantage of the multiroom boxes with five tuners and massive hard drives?
