I hooked up my Samson AirLine Wireless system to my Voodoo Lab Pedal Power ISO 5 using a 9V Battery Snap Cable (PPBAT-R) and it worked perfectly.
I used the battery snap instead of using the DC INPUT 12 VDC on the AirLines Pedal. I believe that calls for a center positive connection but the Samson AirLines manual was not clear about that. And it would have definitely needed the 300mA output.
But the bottom line is I used one of the three 100mA outputs using a Battery Snap Cable and it works perfectly
