Walrus Audio Canvas Mono Line Isolator/Direct Box

The Walrus Audio Canvas Mono line isolator/direct box is built to enhance your signal with clarity and precision, whether you're recording or running live sound. Designed as both a direct injection (DI) and line isolator (LI), this passive unit converts unbalanced signals into balanced outputs, ensuring seamless connection with mixers, live PA systems and recording interfaces. Perfect for guitar rigs, bass, keyboards, digital amp modelers or acoustic setups, the pedalboard-friendly design integrates effortlessly into any signal chain. With its transformer-isolated output and flat frequency response from 20Hz–20kHz, the Canvas Mono delivers clean, distortion-free audio for noise-free routing and gain staging, allowing players to craft pristine, professional-grade tones.

Custom Wound Transformer Ensures Pristine Signal

The Canvas Mono features a custom-wound transformer that minimizes total harmonic distortion (THD) while maintaining a flat frequency response for accurate, transparent tone. This ensures that your sound remains clear and undistorted, even when handling high-gain pedals, digital multi-effects units or nuanced acoustic pickups. Whether routing a digital amp modeler, re-amping a bass DI or sending keys to a mixer, the Canvas Mono offers transformer isolation for consistent signal integrity, making it ideal for both studio DI recording and live noise-free routing.
