Walrus Audio Canvas Stereo

The Canvas Stereo is a Direct Box / Line Isolator designed to remove all resistance between you and your audience by providing a crystal clear sonic foundation upon which to build your stereo masterpiece. From churches to pubs, the Canvas Stereo is made to be the ultimate performance tool wherever you make music.

The Canvas Stereo is a passive Line Isolator (LI) and Direct Injection (DI) device that converts your unbalanced signal into a balanced signal, so you can properly connect it to your recording interface or mixer at the front of the stage.
If you use an amp-in-a-box (DSP guitar amp), or want to connect an acoustic or bass guitar directly, the Canvas Mono is your new bridge to the front of the house. The Canvas Stereo includes everything you need from a DI/LI in a standard pedal enclosure that looks perfect on your pedalboard.

Direct Injection:

Use DI mode when connecting an unbalanced, high-impedance source (electric guitar, bass guitar, etc.). The signal is attenuated by -20dB (or -35dB with the pad enabled) and converted to a balanced signal via the transformer connected to the XLR output.
Use the gain of your mixer or preamp to bring the signal to line level.

Line Isolator:

Use LI mode when connecting an unbalanced, low impedance source (for example, an amp + cabinet simulator such as the ACS1, keyboards, etc.). The signal remains at full volume and is converted to a balanced signal via the transformer on the XLR output. In LI mode, less gain is required from the preamp.

DI or LI?

If in doubt between DI or LI, consult your equipment manufacturer to find out the output impedance of the device you want to connect to. As a general guideline:

• High impedance = anything above 1kΩ → Use DI
• Low impedance = below 1kΩ → Use LI

Troubleshooting:

This is a passive device, so you won't break anything if you connect it wrong, but it can affect signal level and frequency response. This is easy to test because the LI/DI switch is built into the Canvas.
If you lose high frequencies in LI mode, you should probably switch to DI mode.

Features:
