The ISO Power Blocks 6, 6+, 10, and 16 are multi-power supplies for effect pedals and provide up to 16 electrically isolated, highly filtered power connections and a 5V USB connection. The multi-power supply is designed to provide noiseless power to up to 16 effects pedals simultaneously, even with different operating voltages.The advanced filtering technology of the power slots effectively eliminates high-frequency noise. Separate short-circuit protection for each power slot protects the connected effects pedals from damage in the event of a short circuit. Separate LEDs indicate short circuits for each slot separately. Should a short circuit occur, only the affected power slot is switched off, leaving the rest of the effects rig operational.
