An isolated power supply designed for a noise-free pedalboard
The RockBoard ISO Power Block 9 IEC is a multi-output power supply designed to provide a stable and clean foundation for your effects chain, whether you're rehearsing, performing live, or recording. Thanks to its isolated and highly filtered outputs, it helps preserve the dynamics and clarity of the signal, even with power-hungry digital pedals. Its compact form factor fits easily on most pedalboards, while the status LEDs per output simplify daily monitoring. In case of an issue on one line, the short-circuit protection allows the rest of the setup to remain powered without shutting everything down. With its switchable voltages, it adapts equally well to overdrives and compressors as to delays, reverbs, and multi-effects, and the USB output adds a convenient solution to power a compatible accessory.Technical specifications

Questions frequently asked
How many pedals can the RockBoard Power Block Iso V9 IEC power?
This power supply has 9 outputs: 3 fixed outputs at 9 V DC / 500 mA and 3 switchable slots, totaling 6 DC outputs detailed in the specifications. A USB-A output at 5 V / 2000 mA is also included for a compatible accessory.
Are the outputs isolated to prevent pedalboard noise?
The isolated and highly filtered outputs help preserve signal clarity in an effects chain. Short-circuit protection ensures the power supply to other lines is maintained in case of an issue on one output.
What voltages are available on the switchable outputs?
Three slots can be set to 9 V DC / 500 mA, 12 V DC / 375 mA, 15 V DC / 300 mA, or 18 V DC / 250 mA. The voltage is selected according to the electrical requirements of each pedal.
What cables and polarity does this power supply use?
The DC connectors use 2.1 x 5.5 mm barrel plugs with center negative polarity. Nine flat RockBoard power cables of 60 cm length are provided.
What are the dimensions of the RockBoard power supply unit?
The aluminum enclosure measures 195 x 88 x 35 mm and weighs 591 g. Status LEDs per output make it easy to monitor the power supplies on the pedalboard.
