Headroom Heaven The Xotic “Voltage Doubler” is a step-up converter that takes 9 volts DC and boosts it to an output voltage of 15 or 18 VDC (max current draw 80mA). Higher voltage levels result in more headroom. When you boost the voltage your find your Xotic pedals will get much more dynamic, more headroom, top end and brightness, less compressed sound. Simply plug in the power adapter to your existing power source, switch the voltage to either 15 or 18 volts and plug into your pedal. The Xotic Voltage Doubler delivers clean, consistent power with the lowest possible noise.
