Rockboard POWER-block-ISO16 Power Block Iso 16

A Power Supply Designed for Modern Pedalboards, at the Heart of the RockBoard Ecosystem

The Power Block ISO fits into RockBoard's "pedalboard-ready" approach: a compact, organized, and reliable power supply designed to meet the real demands of stage or studio setups. The idea is simple: gather numerous isolated outputs, serious filtering against interference, and coherent current distribution to avoid the proliferation of small adapters and unwanted noise that appears when chaining too many non-isolated power supplies.

Who It's For and What For: Guitar, Bass, Studio, Stage, and Rehearsals

This power supply for effects pedals is aimed at guitarists and bassists who use multiple pedals simultaneously (drive, modulation, delay, reverb, tuner, switcher, etc.) and want a clean, silent, and quick-to-set-up pedalboard. It is equally suitable for studio use, where background noise is immediately noticeable, and for the stage, where reliability and protection against incidents (short circuits, faulty cables) make the difference.

Thanks to its numerous outputs and USB port, the RockBoard Power Block ISO is also a relevant choice if you have a hybrid pedalboard: analog pedals plus one or two more power-hungry digital pedals, while keeping the possibility to charge a nearby USB accessory.

Isolation, Filtering, and Flexibility: Total Control of Your Power Supply

Isolated and Filtered Outputs to Limit Noise

The principle of an isolated power supply is essential on a pedalboard: each output is separated, which helps reduce ground loops and electrical interactions between pedals. The Power Block ISO adds advanced anti-interference filter technology to maintain a cleaner signal, particularly useful with high gain, compressors, or chains including digital pedals.

The external transformer also contributes to reducing interference, especially those related to low frequencies, while keeping the main unit compact on the pedalboard.

Voltages Adapted to Your Pedal Collection

In addition to its dedicated 9V outputs, the Power Block ISO offers 4 switchable outputs allowing you to select 9V, 12V, 15V, or 18V as needed. This is ideal for pedals that benefit from increased headroom at 12V, 15V, or 18V, or for specific effects requiring a particular voltage.

The 2.1 x 5.5 mm connectors with negative center polarity correspond to the most common standard on effects pedals, simplifying daily cabling.

Ready for Real-World Situations: Safety, Visibility, and Useful Cables

Each output features an individual LED and short-circuit protection, a real advantage for quickly diagnosing an issue on the pedalboard. And with the supplied Y-cables (voltage doubler and current doubler), you can more easily organize your power distribution according to your setup while maintaining a clean assembly.
