Look at page 102 schematic of the 1.2 TL
Isn't the ground of one channel simply grounding the "dimensional" channel?
If the amps grounds are common, how are we getting the true dimensional sound meant for the SDA series?
Look at page 100 on the older SRS model, this one is actually sending opposite L and R channels over the cross connect wire.
Have we been duped on the later 1.2 TL series?
