The RockBoard Power Ace IEC Connector Cable provides the perfect extension cord from the RockBoard MOD to a multi power supply.  Connect your IEC mains adapter cable to the front IEC port on your MOD.  The Power Ace IEC Connector Cable then connects the back of the MOD with your multi power supply’s IEC socket without having an unnecessary long cable cable underneath your pedalboard.  This way you won’t ever have to fiddle around underneath your board when setting your rig up on stage!
