The Harley Benton PowerPlant ISO-2 Pro is a seriously impressive value for the money. It's a great solution for pedalboards with a mix of voltage requirements and a need for clean power, especially for those running a lot of digital or modern effects. If you’re building a mid-sized pedalboard and want reliable, isolated power without spending a fortune, this is a solid choice.

Frequently Asked Questions

They are genuinely isolated, meaning there's no bleed-through or interaction between different voltage outputs, reducing noise and potential damage.
Yes, Output A and B can provide 18V, but remember the 500mA current limit applies – check your pedal's power requirements carefully.
The key difference is isolation; standard supplies often have outputs that can influence each other, leading to noise or ground loops – this unit avoids that.
