Description
Introducing the Walrus Audio Canvas Stereo Direct Injection Box, your ultimate bridge from stage to front-of-house. This tool is a game-changer for musicians seeking an uncompromised, high-quality audio performance. Its purpose is to convert your unbalanced signals into balanced ones, ensuring optimal interfacing with your recording interface or mixer, and thereby laying a pristine sonic foundation for your musical masterpiece.
It's designed for music makers of all kinds, whether you are performing in the corner of a downtown dive bar or a grand house of worship. Its versatility makes it an ideal solution for instruments utilizing both left and right outputs, such as keyboards or amp-in-a-box gear like the ACS1.
The Canvas Stereo is also a Passive Line Isolator (LI) and Direct Injection (DI) device, expertly crafted to suit your specific needs.

The Canvas Stereo DI box is designed to be the performance tool that goes wherever you make your music.
