I'm curious about the hookup designations on the 770. All three front channels seem to be on one side of the amp while the surrounds and center are on the other side. This is different than the model 7200 which has the right and left channels on opposite sides of the amp. Is there a reason Outlaw chose to indicate where each channel should be connected and why the change from the 770 to the 7200 if they are basically the same amp with different faceplates?
