You're right, the Outlaw 1070 receiver has no second zone. This was its fatal flaw for me. To get a second zone with Outlaw you have to move up to separates such as the 990 prepro, and there's no need for you to do that with all of the quality receiver options out there.

How does the 3806 compare to the 2807?
