Hallo there... I was looking for a power supply for my Line6 DL4, but, the only one I've found is the Line6 PX2 (due to the HIGH quantity of amperes required by the unit). But... I was reading the features of this power supply and it reads: The PA-9 can power up to three Line-6 Modelers while still having power remaining for other effect units. I wander: how can a 1.7A power supply power up to 3 Line 6 Modelers (still leaving energy for other pedals) if each one of these needs 1.2A to work?! Maybe Line 6 wrote on the back of its pedals that they require 1.2A only to sell THEIR power supply?
