Walrus Audio Canvas Power HP Adapter

Walrus Audio Canvas Power HP — Isolated Power for Modelers and Pedalboards

The Walrus Audio Canvas Power HP is a slim isolated pedalboard power supply built around a single 3A (3,000mA) output for current-hungry devices like the Quad Cortex and HX Stomp. Three additional 9V 500mA isolated outputs cover analog pedals without crosstalk, while a 24V pass-thru links the unit to other Canvas Power supplies from one wall outlet. This supply is the right choice for hybrid rigs that mix a flagship modeler with analog stompboxes. At 25.5mm tall, the chassis slides under most pedalboards and ships with C-style mounting brackets and an IEC cable. Assorted 2.1mm and 2.5mm DC cables in standard and reverse polarity are included.

What Sets the Canvas Power HP Apart

Built on a modern switch-mode supply architecture, each output is individually isolated and heavily filtered to keep ripple noise below audible thresholds. The 3A port switches between 9V and 12V on the fly.

Output Configuration — Power for the Thirstiest Modelers

The headline feature is the single high-current output no standard 500mA brick can match.

• High-Current Output: 1 × 9V/12V switchable, 3A (3,000mA) — runs a Quad Cortex at full 12V 3A
• Standard Outputs: 3 × 9V DC, 500mA isolated — clean power for analog pedals
• Link Port: 1 × 24V DC pass-thru — relays power to additional Canvas Power Link units

Chassis and Mounting — Built to Disappear Under the Board

The slim profile fits beneath elevated pedalboards.

• Dimensions: 133 × 54 × 25.5 mm — fits under most pedalboards
• Weight: 186 g (0.41 lbs) — light enough to mount under a board
• Power Brick: 48W, 24V DC 2A — compact external brick with IEC cable

Cabling and Connectivity — Ready for Any Pedal Out of the Box

Walrus Audio ships a curated set of DC cables.

• Included Cables: 3 × 18" straight-to-right-angle DC, plus 2.1mm standard (yellow), 2.1mm reverse (white), 2.5mm reverse (red), 2.5mm standard (blue)
• Connector Type: 2.1mm barrel — industry standard
• Per-Output Protection: Auto shutoff per socket — wrong-cable detection protects the rest of the rig
