Q) You say your Powerstation can power the Line 6 Stompbox Modellers (DL4, DM4, FM4 & MM4), yet the Powerstation is 9V DC and they require 9V AC. How does that work?

A) The official Line 6 adaptor is indeed 9V AC, however the pedal (as with most electronic devices) is powered by DC internally. You want proof? Well they also run on batteries don't they, and batteries are DC......!

The Green Adaptor is designed so that 9V DC bypasses the bridge rectifier (which converts AC to DC) on the power input. It works just fine with no problems and no detrimental effect on your pedals. Shhhh.....don't tell Line 6!
