Walrus Audio Canvas Power HP

A Power Supply Designed for Today's Pedalboards

With the rise of digital pedals and hybrid setups (analog + digital), power supply quality has become a central link in the sound chain. This modular multiple power supply meets this need with isolated and filtered outputs to maintain a stable signal and a comfortable energy reserve, even when several sensitive pedals share the same pedalboard.

Its "high power" approach clearly targets modern setups: where a standard PSU may reach its limits (noise, voltage drops, dynamic loss), this model focuses on clean, quiet distribution adapted to power-hungry pedals.

For Whom and What? From Home Studio to Stage

This power supply is aimed at guitarists and bassists who want a reliable, quiet, and easy-to-deploy pedalboard. It is suitable for both home studio use (where background noise is immediately noticeable during recording) and stage use (where power stability and build robustness make the difference).

It is particularly relevant if you use one or more digital pedals, complex modulation effects, stereo delays/reverbs, or any device requiring high current. The very high-capacity switchable 9 V/12 V output also allows confidently powering "high current" pedals that often cause issues with more conventional power supplies.

Isolation, Silence, and Current Reserve: Key Points

4 Isolated and Multi-Filtered Outputs

Each output is advertised as isolated and multi-filtered. Practically, this helps prevent the behavior of one pedal (consumption peaks, interference, digital noise) from contaminating the power supply of others. The result: a more stable, cleaner pedalboard and better-controlled background noise, especially with high gain settings or complex chains.

Very High-Power Output for Power-Hungry Pedals

In addition to the three 9 V outputs at 500 mA, the fourth output offers a switchable 9 V/12 V mode with a rated capacity of up to 3000 mA. This is a real advantage for powering pedals with high energy demands without compromising the rest of the pedalboard, while maintaining clean and isolated distribution.

Cabling Designed for Pedalboard Integration

The included cables are designed for practical installation: right-angle plugs on the "pedal" side to better follow the edges of the pedalboard and reduce mechanical strain, and small plugs on the "power supply" side to optimize space. The presence of cables with normal or reversed polarity, as well as 2.1 mm and 2.5 mm connectors, facilitates compatibility with different pedal formats.
