Walrus Audio Canvas Mono Line Isolator/Direct Box

The Canvas Mono from Walrus Audio is a direct box/line isolator designed to remove any resistance between you and your audience by providing a pristine sonic foundation upon which to build your masterpiece. From houses of worship to the dive bar downtown, Canvas Mono is built to be the performance tool that goes wherever you make music. Canvas Mono is a Passive Line Isolator (LI) and Direct Injection (DI) device that converts your unbalanced signal into a balanced signal for direct interaction with your recording interface or mixer at front-of-house. If you’re using an amp-in-a-box (DSP Guitar Rig), like the ACS1, or running an acoustic or bass guitar directly, then the Canvas Mono is your go-to DI. The Canvas Mono packs everything you need from a DI/LI into a standard pedal-sized enclosure designed to look great right on top of your board.

When connecting an unbalanced, high impedance source (Electric Guitar, Bass Guitar, etc), Direct Injection allows the signal to be reduced by -20dB (-35dB with pad engaged) and converted to a balanced signal via the transformer connected to the XLR output. Use the gain on your mixer or preamp to bring the signal up to line level. Use the Line Isolator mode when connecting your unbalanced, low impedance source (Amp + Cab Sim like the ACS1, keys, etc.). The signal will remain full volume and be converted to a balanced signal via the transformer connected to the XLR output. Less preamp gain will be required in LI mode.
