Walrus Audio Canvas Power 15

A modern power supply designed for today's pedalboards

The Canvas Power ( "Power" version ) has a clear goal: to offer a modular multi-output power supply that meets the real needs of current pedalboards, often loaded with digital pedals, loopers, reverbs, and current-hungry delays. Its "clean, silent, and isolated" approach emphasizes stability, interference reduction, and neat integration under the pedalboard, while allowing system expansion via 24 V daisy-chaining with additional modules.

Who is this power supply ideal for, and in what situations?

This power supply is aimed at guitarists and bassists who want a reliable pedalboard for stage, rehearsal, or studio use without compromising on silent operation. Thanks to its numerous isolated outputs, it is especially suitable for mixed setups (analog + digital pedals) and musicians who want to minimize ground loops, hum, and background noise. It's also a relevant solution if you like to evolve your pedalboard over time: you keep a solid base and can expand the power supply via the 24 V linking system.

Key features: stability, modularity, and clean integration

15 isolated outputs for a silent pedalboard

The heart of the system relies on 15 isolated outputs, each capable of delivering 500 mA. This architecture helps maintain stable power and prevents certain pedals (notably digital ones) from injecting noise into the entire chain. The result: a cleaner, quieter pedalboard that's easier to manage on stages where mains power isn't always ideal.

Two switchable variable voltage outputs to broaden compatibility

In addition to the 9V outputs, the Canvas Power includes 2 switchable variable voltage outputs, allowing you to select between 9V (500 mA), 12V (375 mA), or 18V (250 mA). This is particularly useful for pedals that require a specific voltage or for those that gain headroom and dynamics when powered at 18V.

A design optimized for mounting under pedalboards

The power supply is designed to fit under most pedalboards, with mounting brackets compatible with many elevated Pedaltrain models or similar pedalboards. The included cables are also optimized for neat wiring: right-angle plugs on the pedal side to avoid strain, and small, low-profile plugs on the power supply side to facilitate routing and organization under the board.

24 V modularity and USB-C charging

The Canvas Power goes beyond simple distribution: it offers a 24 V input and a 24 V output to connect additional modules via "Canvas Power Link." It also features a convenient USB-C port to charge a phone, tablet, clip tuner, or guitar transmitter (with an appropriate connection), avoiding the need for multiple chargers around your setup.

Clear indication of available power reserve

A LED power meter allows quick visualization of the charge/consumption status (levels at 100%, 50%, 30%, 10%). A real plus for keeping control of your power supply, especially when adding a new pedal or reconfiguring your pedalboard.
