The RockBoard ISO Power Block V10 is a mulit power supply fort effects pedalsthat offers 10 transformer isolated and highly filtered power slots - 8 x 9 volts (isolated) with a max. current output of 150 mA each, und 2 x 18 volts (isolated) with a max. current out put of 400 mA each - for separately powering a total of up to 10 effects pedals simultaneously without any noise. The advanced filtering technology used in each of the power slots prevents high frequency noise. Through individual short circuit protection for each slot, connected effects pedals are effectively protected in case of a short circuit. Individual LEDs indicate short circuits for each of the 9V outputs. In case of a short circuit, only the affected slot is being turned off, so undesturbed use of the rest of the effects pedals is guaranteed.
