Item Type: Guitar Effect Pedal Power Supply AC to DC Adapter Input: AC 100-240V at 50 / 60Hz AC to DC Adapter Output: DC 18V / 4000mA DC Power Supply: 9V 500mA (x6) 9V / 12V / 18V 1000mA (x2) Input: DC 18V / 4000mA LED: Blue LED indicator lights up, green goes out, red stops Conversion Cable: Approx. 3.5mm / 0.1in Plug: US Plug Package List 1 x Power Supply 1 x AC to DC Adapter 8 x DC Cables 1 x Power Cord 1 x 3.5mm Conversion Cable 1 x Polarity Conversion Cable 1 x User Manual 1Up to eight effectors can be connected, the eightway output designed is full isolated, each has a shortcircuit protection function, and two 9V/12V/18V voltage switches. 26 isolated DC outputs 9V 500mA, 2 isolated DC outputs 9v/12V/18v switchable voltage 1000mA 3Full isolated power supply that supports large current output, the current marked by the power supply is the peak current, and the device cannot exceed the set peak power 4The 8 outputs of the power supply are internally negative and externally positive. If the polarity is opposite, please use it with a reverse polarity line. 5FCLC (Foldback Current Limiting Circuit) can provide protection against power shortage and overload, and it is a full regulated power supply even under full load. 6The LED5 at each exit indicator indicates the mode and whether the pedal is faulty (when the LED is red), the power will enter the selfcalibration mode, and automatically restart about 2s after disconnecting the pedal in question.
