Walrus Audio Canvas Power 22

A Modern Response to Current Pedalboard Demands

With the rise of power-hungry pedals (compact multi-effects, digital reverbs and delays, preamps, advanced modulations), the power supply is no longer just an accessory: it determines noise level, stability, and reliability of the entire signal chain. The Canvas Power ( "Power" version ) follows this logic by prioritizing a performance-oriented approach: isolated outputs, comfortable current reserve, and extension possibilities to support pedalboard evolution without starting from scratch.

Who Is This Power Supply For and In What Uses?

This power supply is aimed at guitarists and bassists who want a silent and stable pedalboard, whether in rehearsal, studio, or on stage. It is especially suitable for dense setups (multiple digital pedals, high-consumption pedals, or mixed analog/digital) where a basic daisy chain power supply can generate hiss, interference, or dynamic loss. Its format, designed to fit under most boards, facilitates clean assembly, protects wiring, and frees up surface space for pedals.

Key Features: Isolation, Power, and Flexibility

22 Isolated Outputs: Cleaner Signal and More Reliable Setup

Each output is isolated and capable of delivering 500 mA, a decisive advantage for reliably powering demanding pedals. Isolation helps limit ground loops and induced noise, while preventing one pedal's behavior from affecting another's power supply. The result: a quieter, more predictable pedalboard that is easier to troubleshoot if issues arise.

Two Variable Voltage Outputs to Adapt Pedal Behavior

The Canvas Power includes 2 switchable variable voltage outputs, useful for pedals compatible with 12 V or 18 V, or to seek more headroom depending on the effect type. The three voltage/current settings allow adjustment according to needs: 9 V (500 mA), 12 V (375 mA), or 18 V (250 mA).

24 V Daisy Chain: An Evolving Pedalboard

A 24 V input and 24 V output allow connection of additional "Canvas Power Link" modules. This is a practical approach if your pedalboard expands: you maintain a coherent architecture while increasing the number of available outputs without disrupting wiring.

LED Indicator and USB-C Port: Daily Control and Convenience

A LED power display indicates the level (100%, 50%, 30%, 10%), useful for monitoring available margin. A USB-C port simultaneously allows charging compatible devices (phone, tablet, clip tuner, guitar transmitter), a very handy feature on the go, on stage, or in rehearsal.

Included Cables and Under-Pedalboard Integration

The package includes an appropriate number of cables to power one pedal from each output. The supplied cables are designed for clean wiring: right-angle plug on the pedal side and extra small plug on the power supply side to optimize space under the board. Mounting brackets are included for installation under most elevated Pedaltrain models or similar boards, along with an external power supply unit (24 V, 4000 mA, 96 W).
