Voodoo Lab Pedal Power X4-18V Expander Kit

A Modern Expander in the Pedal Power Ecosystem

The Pedal Power X4-18V Expander Kit follows Voodoo Lab's philosophy: offering a reliable, silent power supply designed for the road, while remaining easy to integrate under a pedalboard. Its compact format and "extension" approach allow you to expand an existing setup without reconfiguring everything, instantly adding additional isolated outputs where needed.

It can be plugged directly into an X-LINK port of a Pedal Power 3 or Pedal Power 3 Plus, or powered from a 12 Volt output capable of supplying 400 mA (depending on the host power supply). It is also designed to operate via the AC output of the Pedal Power 2 Plus, a solution that increases output isolation capacity and available current intensity.

For Which Guitarists and Pedalboards?

This power supply is aimed at musicians who want a solid foundation for a compact pedalboard, as well as those who already have a central power supply and wish to add clean outputs without stacking power strips or noisy adapters. The two 18 Volt outputs are particularly useful for pedals that benefit from increased headroom (overdrives, preamps, compressors, certain EQs), while the 9 Volt outputs meet everyday needs.

It suits both battery-powered pedals and more demanding digital effects, thanks to an appropriate current reserve and an architecture designed to limit interference. It is a relevant choice for concert pedalboards, demanding studio setups, or "fly date" rigs where reliability and silence are non-negotiable.

Key Features and Noise-Reduction Design

Hybrid DC Transformer: Stability and Silence

The Pedal Power X4-18V is based on an innovative DC transformer topology incorporating quality components, with a performance-oriented approach. The goal is clear: to provide a stable power supply capable of handling load variations without degrading the signal, while limiting parasitic noise that can appear with some entry-level switching power supplies.

Linear Regulation and Optimized Filtering

Voodoo Lab relies here on linear regulation combined with computer-optimized advanced filtering. Practically, this aims to reduce hiss, whistling, and interference, especially when multiple pedals share a confined space and power supplies are close to audio cables. The expected result is a "noise-free" power supply that respects transients and dynamics, including with sensitive digital effects.

Simple Extension of an Existing Power Supply

The X4-18V can serve as an additional power supply to extend an existing system. In "expander" use, it adds 4 isolated outputs to a compatible Voodoo Lab power supply, allowing for example to separate digital pedals from analog pedals, or to reserve the 18 Volt outputs for specific effects without compromising the rest of the chain.

Worldwide Compatibility

Designed for mobile musicians, it operates on mains voltages worldwide, from 100 Volts to 240 Volts AC. A real advantage for playing abroad, touring, or simply anticipating a change of environment without needing to change the power supply.
