The RockBoard ISO Power Block V6 is a multi-power supply for effects pedals with 5 isolated transformers and highly filtered 9V DC power slots and a single 18V DC link output to connect multiple ISO Power Blocks V6 in series for larger setups. The advanced filtering technology used in the 9V DC power slots prevents high-frequency noise. Built with individual slot short circuit protection, connected effects pedals are protected in case of a short circuit. With a designated LED for each power slot indicating the slot is working correctly, you can quickly identify any problems without losing power to the rest of your rig.
