The 1 Spot Pro XP5 is a tiny little powerhouse which allows you to add 5 more isolated outputs to your CS11.  Each output provides 9Vdc of studio-clean power and can handle at least 500mA of current draw per output.  Measuring 88x88x30mm (3.46x3.46x1.18”) and weighing only 333 grams (11.75oz), it can be easily attached to a pedalboard using only Vel-Cro.  Because of its low profile, the XP5 can be mounted under most pedalboards or be used as a pedal riser on top of a board.  With 2 linked input jacks, you can power a second XP5 or XP8 by simply connecting a DC cable.
