Canvas Stereo Passive Line Isolator + DI Box (2025)

Walrus Audio Canvas Stereo

Whether you're playing lush, wide synth pads or guitars with rich stereo delays and want to be sure the venue is getting the best signal possible, Walrus Audio's Canvas Stereo is the DI box and line isolator for the job. Totally passive and packed into a pedal-sized box, Canvas contains two custom-wound transformers for delivering pristine audio to front of house or your audio interface. Simply patch your instrument into the 1/4" unbalanced inputs, and you'll get clean, balanced signals from the XLR outputs.

The versatility of Canvas shines through with its ability to function as either a DI box or line isolator. The concept is similar, but DIs are optimized for high-impedance source, like acoustic guitar or bass, while LIs work great with synths or amp modeler outputs. For further utility, there's also siwtches for -15dB Pad, Sum functionality with the Thru jacks, and Ground Lift. Get your stereo audio signals prepared for the outside world with Canvas Stereo by Walrus Audio.
