Isolated power is the best way to protect your signal path from unwanted noise and interference. The Big Joe Power Box provides eight Isolated, noise free, 9v DC power outputs: six 100mA and two 300mA. Various switch combinations allow 12V and 18V outputs options. Two of the outputs also feature variable (VAR) voltage controls to simulate worn out batteries. An AC courtesy jack for pedals requiring AC only is provided in the back, and multi color LED's for each of the eight outputs makes it easy to see the voltage selected for each output.Features:Eight (8) isolated 9v DC power outputsSlide switch to convert to two 9v outputs to 18VSlide switch to convert four 9v outputs to 12vSlide switch to convert two 9v outputs to variableRegulated and unregulated outputsMulti color LED output voltage indicatorsAC power output jackWhat’s Included:1- Big Joe Power Box1- Power cord4- Connector Cable, 5.5mm X 2.1mm, male/male, short4- Connector Cable, 5.5mm, x 2.1mm, male/male, long1- Adapter Cable, 2.1mm, reverse polarity, female/male- red1- Adapter Cable, 2.5mm, reverse polarity, female/male- green1- Adapter Cable, 3.5mm, reverse polarity, female/male -blue2- Battery Snap Cable, 9 volt adapter, black
